linux based


First of all, Linux audio is a bit different than Windows. There is no Killer application like cubase, which has all the features you need builtin (although Ardour is the one application which tends to get near) . Nevertheless, Linux audio is really powerful beause of the audio and midi I/O routing capabilities. Basically, you can build stream chains between programs, routing the signals as you like. So the possibility to combinate programs IS Linux audio. This is accomplished through JACK. The Jack audio connenction kit does its magic upon other technologies like ALSA, OSS4, pulse audio. All have their place, some do the same thing; Many things to know (and to explore) here. See Background technologies. Generally, if you click an application in audio, jack will be started in background for you (except for the ones that do not need it) You can also start jack (via jack control) before starting any audio applications. This gives you more control. Samplerate, etc.

the apps are divided in three goups

Have you ever wanted to take the audio output of one piece of software and send it to another? How about taking the output of that same program and send it to two others, then record the result in the first program? If so, JACK may be what you've been looking for.

JACK is a low-latency audio server, written for POSIX conformant operating systems such as GNU/Linux and Apple's OS X. It can connect a number of different applications to an audio device, as well as allowing them to share audio between themselves. Its clients can run in their own processes (ie. as normal applications), or can they can run within the JACK server (ie. as a "plugin").

JACK was designed from the ground up for professional audio work, and its design focuses on two key areas: synchronous execution of all clients, and low latency operation. More background information is available.

PulseAudio is a sound server for POSIX and Win32 systems. A sound server is basically a proxy for your sound applications. It allows you to do advanced operations on your sound data as it passes between your application and your hardware. Things like transferring the audio to a different machine, changing the sample format or channel count and mixing several sounds into one are easily achieved using a sound server. > Wiki > Pulseaudio

Automatically change Sound Input Output device, have to plugin my USB Audio adapter ( 4300054 Gigawire USB Audio Adapter) for audio input because has a combo-input-output port for voice. After I do this, I have go open Sound Settings and manually select the USB Audio adapter for Input and Output, if I do not, the system default remains selected., Is there anyway, I can make Ubuntu to automatically select the USB Audio Adapter as the default as soon as I plug-in?, There is pulseaudio module-switch-on-connect that enables automatic switching of an audio device on connection. To test if this works we may issue the following commmand in a terminal:, pacmd load-module module-switch-on-connect, On success we can add the following line to our /etc/pulse/, load-module module-switch-on-connect, to always load this module on every login, resp. restart of the pulseaudio daemon.

Media streaming Open and unencumbered media streaming solutions:


a place for various audio related libraries being developed for the Praxis InterMedia System that may be of more general use.

A common guiding principle of these projects is that they provide the simplest possible API based wherever possible around standard Java classes.

JNAJack is a minimal object-oriented wrapper to the JACK Audio Connection Kit API. It uses Java Native Access (JNA) rather than custom JNI to interface with the underlying Jack API, simplifying development and deployment (no compilation required!). Unlike JJack, the other Java binding for Jack, the aim of this project is to support direct (OOP) access to the Jack API from Java (and nothing else). Most important aspects of the audio API are included. MIDI and transport support will be implemented in the future.

If you're just looking to write an audio client for JACK in Java, you are recommended to use the AudioServers API below, which abstracts out the complexity of working with the JACK API, and means that your client can work with any AudioServer implementation.

AudioServers, The aim of this project is to provide a simple client-server callback model for audio IO, providing a minimal API that removes the need for audio processing code to have any knowledge of the underlying audio library. The release includes server implementations providing low-latency JavaSound support (with configurable timing mechanisms) and Jack support through JNAJack., Have a look at Getting Started with the AudioServers API, or have a look through the JavaDoc

mp3 oder m4a

Der nackte Vergleich von einer 128kbit/s mp3-Spur mit einer m4a-Spur wird wohl qualitativ zugunsten des AA-Codecs ausgehen. Dennoch kann man mithilfe des LAME bei der Codierung von mp3 noch eine ganze Menge rausholen. Beispielweise kann man sogenanntes Joint-Stereo einsetzen, welches Kompression deutlich verbessert (-> Wikipedia erklärt). Auch durch variable Bitrate im Bereich von...bis besteht die Möglichkeit, die Kompression gezielter einzusetzen und so die Qualität noch zugunsten von mp3 zu verbessern.

mp3-Dateien würde ich ausschließlich mit LAME codieren. Wikipedia schreibt hier:

Auch ist LAME in der Regel langsamer als Encoder anderer Kompressionsverfahren. Die Ursachen dafür liegen zum Beispiel im psychoakustischen Modell und anderen internen Funktionen, die dazu dienen, die Ausgabequalität zu verbessern. Die langsame Verarbeitung kommt also direkt der Qualität zugute.

Unterhalb 128kbit/s ist meines Wissens Vorbis AAC überlegen. Oberhalb 192kbit/s verschwimmen die Unterschiede. Die meisten würden auch oberhalb 192kbit/s keinen Unterschied zur CD feststellen, nach meiner Meinung. > Blog > Entry > The-state-of-firewire-audio-interfaces-support-on-linux

about, DSSI LADSPA Plugins

Rubber Band, is a software library for audio time-stretching and pitch-shifting., it does also include a simple command-line utility program that you can use for simple adjustments to the speed and pitch of existing audio files.

BLOP - Bandlimited Oscillator Plugins, Bandlimited wavetable-based oscillator plugins for LADSPA hosts BLOP comprises a set of LADSPA plugins that generate bandlimited sawtooth, square, variable pulse and slope-variable triangle waves, for use in LADSPA aware audio applications, principally as components of a modular synthesis network. They are wavetable based, and are designed to produce output with harmonic content as high as possible over a wide pitch range. Additionally, there are a few extra plugins to assist in building synthesis networks, like a analogue-type sequencer, sync-square and ADSR envelope.

cmt - Computer Music Toolkit, Computer Music Toolkit (cmt) a collection of LADSPA plugins cmt -- Computer Music Toolkit -- is a collection of LADSPA compatible plugins that any conforming program may take advantage of. Plugins available are: low/high pass filters, echo/feedback delay filters with configurable delays from 0.01 to 60 seconds, amplifies, white and ping noise generators, compressors, expanders, limiters, b/fmh encoders, drum synthesizers, lofi (low fidelity), phase modulator (phasemod) and many more

mcp, LADSPA plugins designed for Alsa Modular Synth MCP plugins implement a set of LADSPA plugins that vastly improve the sound of AlsaModularSynth. Currently they consist of these plugins: * Moog VCF (1-3): Moog lowpass filters that quite successfully emulate the properties of the analogue circuit. Version 3 of these filters is recommended. * Phaser1: A phaser with up to 30 all-pass filters in series. * Phaser1+LFO: The same as above, but with built-in LFO. LFO waveform can be continuosly changed from saw down to triangle and saw up. * Chorus (1,2): Two chorus plugins.

fil-plugins - parametric equalizer LADSPA plugin, Four-band parametric equaliser. Each section has an active/bypass switch, frequency, bandwidth and gain controls. There is also a global bypass switch and gain control. The 2nd order resonant filters are implemented using a Mitra-Regalia style lattice filter, which has the nice property of being stable even while parameters are being changed. All switches and controls are internally smoothed, so they can be used 'live' without any clicks or zipper noises. This should make this plugin a good candidate for use in systems that allow automation of plugin control ports, such as Ardour, or for stage use.

omins - a collection of LADSPA plugins aimed at modular synthesizers, These plugins are provided: Range translator, Formant filter, AD Envelope, DAHDSR Envelope, Hz to V/Oct converter, Comparison, Fast Crossfade, Masher, Multiplexer, Power, Probability Switch, Sample and Hold, Signal Absolute Value, Slew Limiter, Slide, Waveguide Mesh

swh-plugins - Steve Harris's LADSPA plugins, Steve Harris has written a large number of plugins for LADSPA compatible hosts (e.g. GLAME, Sweep and ecasound). The plugins available are: amp, fast overdrive, overdrive (with colourisation), comb filter, waveshaper, ringmod, divider, diode, decliper, pitch scaler, 16 band equaliser, sinus wavewrapper, hermes filter, chorus, flanger, decimater, oscillator, gverb, phasers, harmonic generators, surround encoders and more.

Tom's Audio Processing LADSPA plugins, Tom Szilagyi has written a number of plugins for LADSPA compatible hosts (e.g. Ardour, GNU Sound and GStreamer). The plugins (Equalizer, Reverberator, Stereo Echo, Tremolo, Scaling Limiter, AutoPanner and DeEsser) have been written primarily for Ardour but should work well with any LADSPA host. Homepage:




about, the Disposable Soft Synth Interface or DSSI is a plugin architecture for software synthesizers to be run under Linux. There are currently a few software synthesizers designed for DSSI including:, * FluidSynth-DSSI, a FluidSynth soundfont-playing plugin., * Xsynth-DSSI, an analogue-style (VCAs-VCF-VCO) synth plugin., * hexter, a Yamaha DX7 modelling plugin., * ll-scope, a GTK+ oscilloscope plugin., * Sineshaper, a waveshaping synth plugin., * dssi_convolve, a DSSI wrapper around libconvolve, providing a friendly convolution plugin for reverb effects (among other uses)., * xy-controller-dssi, a GUI controller plugin which translates mouse input into X-Y control outputs., * WhySynth, a synth plugin featuring four oscillators per voice, multiple oscillator, filter, and envelope modes, effects, and more., * Wsynth-DSSI, a wavetable synth written with the PPG Wave and Prophet VS in mind., * nekobee, a synth plugin that emulates the sound of the TB-303 Bassline., These synths can be used directly within the Rosegarden or MusE sequencers without having to patch them via JACK (although you can run them as seperate applications and patch then with JACK if you want). One of the most attractive benefits of the DSSI package is that Linux musicians can use many Windows VST instruments and effects using Wine. The huge benefit to Linux musicians is that because DSSI uses the LGPL licence, it can be distributed as a binary compared to fst-vst which has to be compiled by every user because of the GPL., How to use Windows VST instruments and effects in JAD using dssi-vst,, > Content > Downloads, > Wiki > DSSI

dssi-vst-ladspa wrapper vst for ladspa., dssi-vst exposes a LADSPA descriptor as well as a DSSI descriptor. This change permits you to use dssi-vst to load VST effects in LADSPA hosts, as well as to load VST effects and instruments in DSSI hosts as before. When used in a LADSPA host, the VST GUI will not be shown unless the host supports DSSI-style GUIs for LADSPA plugins as well -- which most do not.

FluidSynth-DSSI, FluidSynth, The FluidSynth-DSSI package contains FluidSynth-DSSI, a wrapper for the FluidSynth SoundFont-playing software synthesizer, allowing it to function as a DSSI plugin. (This was formerly part of the main DSSI package.), > Wiki > FluidSynth

xsynth-dssi, xsynth-dssi package contains the Xsynth-DSSI plugin, a classic-analog (VCOs-VCF-VCA) style software synthesizer with an editor GUI.

dssi-vst, The dssi-vst package contains a wrapper plugin for Windows VSTs that enables them to be used by DSSI hosts running on Linux or similar on i386, using Wine. To use dssi-vst: make sure DSSI_PATH is set appropriately, set VST_PATH to a colon-separated list of the directories containing VST plugins, and start up your DSSI host. The plugin soname is, and each VST plugin gets a label corresponding to its DLL name. So for example, with jack-dssi-host, you should be able to just run jack-dssi-host

hexter (dssi), hexter is a plugin which models the sound of a Yamaha DX7.

Aeolus, Synthesised pipe organ emulator Aeolus is a synthesised (i.e. not sampled) pipe organ emulator that should be good enough to make an organist enjoy playing it. It is a software synthesiser optimised for this job, with possibly hundreds of controls for each stop, that enable the user to "voice" his instrument. Main features of the default instrument: three manuals and one pedal, five different temperaments, variable tuning, MIDI control of course, stereo, surround or Ambisonics output, flexible audio controls including a large church reverb. Aeolus is not very CPU-hungry, and should run without problems on a e.g. a 1GHz, 256Mb machine., Stop and instrument definitions for Aeolus-0.6.x, This package contains definitions of stops and of an instrument, to be used with the aeolus organ synth.

ll-scope, an oscilloscope DSSI plugin The Oscilloscope is a DSSI plugin with a GUI that displays the audio input in an oscilloscope view. It can be useful when working with modular synths, to view the waveforms with at different places in the synth graph




wineasio, wineasio provides an ASIO to JACK driver for WINE., ASIO is the most common Windows low-latency driver, so is commonly used in audio workstation programs. (Wine's built-in JACK transport isn't a Windows ASIO driver.) Note: After install as user run the following command to make wineasio known. regsvr32 wineasio.dll Wine ASIO allows specifying the number of inputs and outputs via environment variables.

qJACK Control

<html><img src="jackctl.png">

the Jack Control Interface. the main application required for music production under Linux. Nearly all Linux music software requires that the JACK server be running before you can use them as it controls the routing of audio and midi data. Note that some audio hardware tends to record much better at 48000Hz rather than the standard 44100Hz of CD audio. The sampling rate and bit depth (audio quality) of your audio projects must be set under qjackctl before you start it. The application is set to start Jack @ startup. Also, it will start minimized into tray.

Provides a simple GUI dialog for setting several JACK daemon parameters, which are properly saved between sessions, and a way control of the status of the audio server daemon. With time, this primordial interface has become richer by including a enhanced patchbay and connection control features.

JACK Timemachine

a simple jack app to record the last 10 seconds of audio to the disk and then catch up to realtime and kept recording.

has the advantage that it never clips and can be wired to any part of the jack graph.

The idea is that I doodle away with whatever is kicking around in my studio and when I heard an interesting noise, I'd press record and capture it, without having to try and recreate it. :)


Audio Recorder

Easy-to-use audio recording tool. an audio recorder application.It allows you to record your favourite music and audio to a file. It can record audio from your system's soundcard (via pulseaudio), microphones, browsers, webcams & more. Put simply; if it plays out of your loudspeakers you can record it.

It has an advanced timer that can:, * Start, stop or pause recording at a given clock time., * Start, stop or pause after a time period., * Stop when the recorded file size exceeds a limit., * Start recording on voice or sound (user can set the audio level and delay)., * Stop or pause recording on "silence" (user can set the audio level and delay).

The recording can be atomatically controlled by:, * RhytmBox audio player., * Banshee audio player., * Amarok and other MPRIS compatible players., * Skype. It can automatically record all your Skype calls without any user interaction.

This program supports several audio (output) formats such as OGG audio, Flac, MP3 and WAV.

please bear in mind that you will have to have PulseAudio running to record from sound output (line in or microphone is also working with alsa only.)


a simple but solid recording tool. qarecord works well with both stereo and multichannel recordings, with both ALSA and JACK, and in both 16 bit and 32 bit mode. By using a large ringbuffer for the captured data, buffer overruns are avoided.

MIDI trigger, In addition to the buttons in the GUI, recording can be started and stopped via MIDI. qarecord uses the ALSA sequencer for this purpose.

File naming, A save file dialog appears the first time recording is activated, or through selecting New... in the File menu. If that file already exists, the old file will be renamed (to filename.oldx.wav), where x is an incrementing number. Should the file grow larger than the split limit, the file will be closed and recording will continue in a new file filename.partx.wav, where x is an incrementing number.

Scheduling and priorities, qarecord has one high-priority thread that fetches data from ALSA and one normal priority thread that writes the data to disk. This will work best if the user is allowed to run realtime priority (rtprio) threads, for more information. In JACK mode, the same reasoning applies, but it is handled by JACK. A ringbuffer is used to buffer the data before it is written to disk.

some Options:, --32bit ; If specified, a 32 bit WAVE will be the output format. If not specified, a 16 bit WAVE file will be recorded., --jack ; If specified, qarecord works as a JACK client. If not specified, qarecord uses ALSA for recording., --device ALSA device ; The ALSA device name to use for capture. The default is plughw:0, which means the first soundcard., --rate Hz ; Sample rate. The default is 44100., for more options, see man qarecord.

Note that when recording from ALSA, you cannot choose what to record in qarecord, this has to be choosen in the capture section of an alsa mixer, e.g alsamixer.

sound editors




mhWaveEdit is a graphical program for editing, playing and recording sound files. It is lightweight, portable, user-friendly and handles large files very well.

The program itself has only simple editing features such as cut'n'paste and volume adjustment but it can also use Ladspa effect plugins and the effects provided by the SoX application. It can also support additional file formats besides wav through libsndfile and mp3/ogg import and export through lame and oggenc/oggdec.


via wine. a frame based editor for MPEG audio (Layers 2 and 3).

You can cut, copy, paste or change the volume without re-encoding anything of the file. This makes mp3DirectCut very fast and prevents loss of audio quality, because nothing will be re-encoded. The program enables easiest navigation even on large files and gives you a visualisation of the MP3 audio data. It can handle Cue sheets allowing to split a file at cue positions. Pause detection or Auto cue you can easily divide long files. And you can also directly record and encode an MP3 from your audio input device.

Features:, Non-destructive cut, copy, paste, Volume change, fade, normalize, pause detection, mp3 recording with ACM or Lame encoder, Fast mp3 visualisation and easy navigation, Supports Layer 2 (dvd/dvb audio), ID3v1.1 tag editor · ID3v2 tag keeping, Cue Sheet support, Auto cue (track dividing by time values), Track splitting with filename and tag creation, Trim · Crop · Fast play · Loop play, VU meter, bitrate visualisation, High speed recorder · Command line usage, Unicode support

Sweep operates on various 8/16/24/32 bit PCM files. Other major formats handled are GSM 6.10, G721, G723, NIST Sphere and DWVW

Sweep contains filters and effects you can apply to sound. One of its best features is "scrubbing". The scrub tool provides immediate audio feedback when jumping to specific portions of a file. This is something you will appreciate if you are a DJ.

Sweep also allows discontinuous selections, multiple views of a sound sample and piano-style playback. Sweep has full support for multi-channel files and for multiple levels of undo and redo.

Gnome Wave Cleaner

Sound File Noise Reduction. an application that helps you in getting rid of noise and clicks in audio files. This is most commonly used when translating your old vinyl or old tapes to a digital format, but it can be applied to every soundfile that has a more or less constant noise level.



AutoTuner. an 'autotuner', normally used to correct the pitch of a voice singing (slightly) out of tune. Compared to 'Autotalent' it provides an improved pitch estimation algorithm, and much cleaner resampling. AT1 does not include formant correction, so it should be used to correct small errors only and not to really transpose a song. The 'expected' pitch can be controlled by Midi (via Jack only), or be a fixed set of notes. AT1 can probably be used on some instruments as well, but is primarily designed to cover the vocal range. It's also usable as a quick and dirty guitar tuner.


Reverb. REV1 is a reworked version of the reverb originally developed for Aeolus. Its character is more 'hall' than 'plate', but it can be used on a wide variety of instruments or voices. It is not a spatialiser - the early reflections are different for the L and R inputs, but do not correspond to any real room. They have been tuned to match left and right sources to some extent.

Ardour VST

Ardour Digital Audio Workstation (With VST Support)


via wine. a free, Open-Source, music creation program that offers an easy way to create your own music, fast, and with high quality.

Psycle uses a classical tracker interface (a text grid of notes which are sequenced one after the other), coupled with modularity (plugins) that allow to extend the sounds that you get from it.

It supports three ways to get sound: its own native format, the VST Plugin standard, and recorded .wav samples using the sampler machine.

Notes are entered in patterns, where you can also use commands (plugin specific, or global), as well as automating parameters via the mcm and twk commands.

These patterns are then organized in a linear sequence, which becomes the song order.

Features, - A 64 Tracks Pattern Editor, with up to 1024 lines., - 256 sequence positions., - Audio Routing (machine) view to interconnect the virtual machines in order to apply different effects., - Internal Stereo Sampler unit which supports .wav and .iff files of any sampling rate, 8/16 and 24bits, mono or stereo., - 70+ Native Plugins (generators & effects), most of them open-source and with an easy to use API to create new ones., - Importing of .xm .s3m .it .mod's., - Exporting to wav, as well as recording realtime to .wav n\- Configurable Keyboard Layout, - Midi-In Support ( control Psycle using a midi keyboard, or even a software sequencer), - Themes and skins support, - Support for VST1 and VST2 plugin standard.

Dynamic beat slicing, multichannel audio support, intelligent automation thinning, flexible multiple MIDI hardware device and sysex support, fast controller-to-plugin mapping. Fully automatic plug-in delay compensation (PDC)

REAPER doesn't have track types, busses, tools, or offline processing. Any track can be a bus, and any track channel can be sent anywhere else. Sends are just dragged from one track to another. For Sidechaining, drag a send from the source to the target, select the plug-in knob you want to sidechain, and press a button.

Because REAPER doesn't have track types, you can use an audio gate to write MIDI triggers right on the same track. Or, render a virtual instrument from MIDI to audio as a new take. You can insert MIDI track controls at any point in the signal chain, to control MIDI pan (or anything else) both upstream and downstream of a MIDI plugin.

Every item has handles for fades, snap points, volume, per-take FX, and more, so you can work intuitively without constantly switching tools or keeping track of what mode the mouse is in. firewall VST plug-ins in their own process space to maximize RAM utilization and protect against plug-in crashes bringing down the whole project. A firewalled Win32 VST plug-in can be configured to use up to 3GB of RAM all for itself, without sharing memory space with REAPER or any other plug-in.


freely mix audio and MIDI routing, even within a single track. REAPER's parameter modulation allows you to creatively sidechain midi and audio: drive your synth's cutoff filter with an audio signal, or create midi triggers with an audio gate. You can even script your own JS MIDI processing plug-ins and customized game controller-to-MIDI support.

At the Sounding Edge: A September Trio

Sooperlooper / LADSPA







The LinuxSampler project was founded with the goal to produce a free, streaming capable, open source pure software audio sampler with professional grade features, comparable to both hardware and commercial Windows / Mac OS X software samplers and to introduce new features not yet available by any other sampler in the world.

LinuxSampler was designed very modular, especially (and in contrast to other samplers) it was decoupled from any user interface. LinuxSampler itself usually runs as its own process in the background of the computer and usually does not show up anything on the screen, or at most it can be launched to show status information and debug messages in a console window.

That means LinuxSampler itself is the "engine" of the sampler, it is the software component which performs all the heavy and time critical computational tasks of handling MIDI events, calculating the audio data and sending the final audio data to your sound card(s). The dev team call LinuxSampler the "sampler back-end".

Obviously you need some way to control the sampler. That's where a 2nd application comes into game - a sampler front-end application. A front-end is (usually) a graphical application, visible on the screen, providing the user a set of e.g. menus, buttons, sliders, dials, etc. to allow the user to control the sampler in a convenient way. It merely sends the user requests to the sampler engine (LinuxSampler) and in turn shows the engine's status information on the screen. A front-end does not perform any signal processing tasks, so you can see it as a "face" of the sampler.

Two different front-ends / "faces" for LinuxSampler are provided:

QSampler is a light-weight front-end written in C++, using straightforward native graphical controls of the underlying operating system. That way the appearance of QSampler on the screen is very fast and it consumes very little resources. Due to its utilization of the operating system's common GUI controls, it looks slightly different on every operating system (also dependent of the user's selected theme on his OS). Note however, QSampler does not fully support all features of the sampler engine (LinuxSampler), yet. Most notably the engine's instruments database feature is not yet covered by QSampler.

JSampler is a full-fledged front-end for LinuxSampler, written in Java and currently comes in two flavors: JSampler "Classic" offers straightforward GUI controls whereas JSampler "Fantasia" provides a modern skin based user interface. JSampler supports all features currently available in the sampler engine (LinuxSampler). Also note that even though JSampler is written in Java and slightly more hungry regarding resources (compared to QSampler), this usually does not have any impact on the audio rendering performance of the sampler, since the engine runs completely independently and with much higher CPU priority than the front-end(s).

Supported Sample Formats (loads or saves) include, Gigasampler Engine, DLS Engine, Akai Engine > Product > Linuxsampler by the linuxsampler project > Features

tracker / buzzalike







Psycle supports highsample rates, comes with a selection of internal machines that actually make need for VST (at least free ones) virtually irrelevant, it's very flexible and it's fun to use. And btw it runs on Linux Ubuntu under Wine quite smoothly (just in case).

Free. No nags. No limitations. No annoyances. Nice community. If you're not scared about hex numbers, it may be for you.






sound coding / experimental



see VJ->Puredata

a real-time graphical programming environment for audio, video, and graphical processing. It is easy to extend Pd by writing object classes ("externals") or patches ("abstractions"). The work of many developers is already available as part of the standard Pd packages and the Pd developer community is growing rapidly. Recent developments include a system of abstractions for building performance environments; a library of objects for physical modeling; and a library of objects for generating and processing video in realtime.

All the possible externals and their combinations cannot be put into a menu. You can however and EXPLORE and START these. Explore them in

/opt/pd/lib/pd/extra. The docs for them are in /opt/pd/lib/pd/doc. You can reach the docs and patches (.pd files) through pd, though. In pd, click Help>Browser, it starts in the doc dir. extra folder is linked into docs for convenience. In pd, the documentation is also IN the patches.

START via commandline, e.g. with

pd -lib Gem:py

you start the Gem AND the py external. 80+ externals wait to be discovered. Read their help how they get started, that can be different. pd --help is a place to find out about startup options.

Have attention to the /opt/pd/lib/pd/extras/abstractions folder. Many examples there,some help too.

Also, have a look at /opt/pd/lib/pd/doc/manuals of extra's. And again, Help>Browser is your friend!

Virtual MIDI Piano Keyboard

<html><img src="vmpk-linux.png">

a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player. To do so, connect the other MIDI port to the input port of VMPK.

The alphanumeric keyboard mapping can be configured from inside the program using the GUI interface, and the settings are stored in XML files. Some maps for Spanish, German and French keyboard layouts are provided.

VMPK can send program changes and controllers to a MIDI synth. The definitions for different standards and devices can be provided as .INS files, the same format used by QTractor and TSE3. It was developed by Cakewalk and used also in Sonar.

JACK diagnostic tool.

bitmeter operates at the bare metal of JACK's I/O layer, looking at the 32 binary digits in each individual sample.

There are three main areas to the bitmeter display:, * Statistics, at the top, including the range of sample values and keeping, a count of irregular and illegal sample values such as NaN. The statistics, on the right are cumulative, and should ordinarily read zero., * Sign & Mantissa, a row of 24 coloured indicators showing the sign, (positive or negative) and mantissa of the samples., * Adjusted scale, 40 smaller coloured indicators.

The sign and mantissa statistics are show as coloured indicators which map to bits in the samples processed by the bitmeter, with the left most indicator representing the sign bit, and then the mantissa left to right from most significant to least significant. The colour is based on the percentage of samples in which the associated bit was 1 over a period of 100ms or so. Blue indicates that all samples were 0, a light green-blue for up to 33%, green for 33-66% (i.e. about half), and orange for more than 66%, then finally red if all samples are 1, a possible "stuck bit". Gray is used when no samples touched the associated bit.

The "adjusted scale" shows each sample bit on a absolute scale, adjusted for the exponent of the sample, so that internally the bitmeter records a 280-bit binary real. For simplicity only 40 bits are displayed, the 8 left-most bits are the integer part, and the remaining 32 bits after the marker are fractional bits.

The audio range of the adjusted scale is from about 200dB below FS to 40dB above, which would be excessive for audio work but proves useful in diagnosing problems at a lower level.

The sample rate reported by bitmeter is directly from JACK. It's not used to perform any calculations and is purely informative. .

view and analyze audio files.

With Sonic Visualiser you can:

* Load audio files in various formats (WAV/AIFF, plus Ogg and mp3 if compiled in) and view their waveforms

* Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters

* Annotate audio data by adding labelled time points and defining segments, point values and curves

* Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on

* Import annotation data from various text formats and MIDI files

* Play back the original audio with synthesised annotations, taking care to synchronise playback with the display position

* Slow down and speed up playback and loop segments of interest, including seamless looping of complex non-contiguous areas

* Export annotations and audio selections to external files.

* Sonic Visualiser can also be controlled remotely using the Open Sound Control (OSC) protocol.

<html><img src="sonicvisualizer.png"></html>

Sonic Visualiser is an application for viewing and analysing the contents of music audio files. The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it.

As well as a number of features designed to make exploring audio data as revealing as possible, Sonic Visualiser also has powerful annotation capabilities to help describe what you find, and the ability to run automated annotation and analysis plugins.

Features include sophisticated spectrogram views; multi-resolution waveform and data displays; manual annotation of time points and curves; measurement capabilities from spectrogram and spectrum; playback at any speed; looping and playback of discontiguous selections; ability to apply standard audio effects and compare the results with their inputs; and support for onset detection, beat tracking, structural segmentation, key estimation and many other automated feature extraction algorithms via Vamp audio analysis plugins.

Sonic Visualiser contains features for the following:, Load audio files in WAV, Ogg and MP3 formats, and view their waveforms., Look at audio visualisations such as spectrogram views, with interactive adjustment of display parameters., Annotate audio data by adding labelled time points and defining segments, point values and curves., Overlay annotations on top of one another with aligned scales, and overlay annotations on top of waveform or spectrogram views., View the same data at multiple time resolutions simultaneously (for close-up and overview)., Run feature-extraction plugins to calculate annotations automatically, using algorithms such as beat trackers, pitch detectors and so on., Import annotation layers from various text file formats., Import note data from MIDI files, view it alongside other frequency scales, and play it with the original audio., Play back the audio plus synthesised annotations, taking care to synchronise playback with display., Select areas of interest, optionally snapping to nearby feature locations, and audition individual and comparative selections in seamless loops., Time-stretch playback, slowing right down or speeding up to a tiny fraction or huge multiple of the original speed while retaining a synchronised display., Export audio regions and annotation layers to external files.

The design goals for Sonic Visualiser are:, To provide the best available core waveform and spectrogram audio visualisations for use with substantial files of music audio data., To facilitate ready comparisons between different kinds of data, for example by making it easy to overlay one set of data on another, or display the same data in more than one way at the same time., To be straightforward. The user interface should be simpler to learn and to explain than the internal data structures. In this respect, Sonic Visualiser aims to resemble a consumer audio application., To be responsive, slick, and enjoyable. Even if you have to wait for your results to be calculated, you should be able to do something else with the audio data while you wait. Sonic Visualiser is pervasively multithreaded, loves multiprocessor and multicore systems, and can make good use of fast processors with plenty of memory., To handle large data sets. The work Sonic Visualiser does is intrinsically processor-hungry and (often) memory-hungry, but the aim is to allow you to work with long audio files on machines with modest CPU and memory where reasonable. (Disk space is another matter. Sonic Visualiser eats that.). > Product > Sonic-visualiser-by-centre-for-digital-music-at-queen-mary-university-of-london

supports a number of different types of meter, rendered using the SDL library and user-editable pixmaps.

SCO - Scope, A rendering of an oscilloscope display., It has a basic trigger function, but there is no timebase control. It renders one pixel per sample, so it will probably be next to useless at 96KHz, Scope

JF - "Jellyfish" Meter (aka. Goniometer), A jellyfish meter is a stereo scope display, it can be used to spot phase and mono compatibility problems., Some charateristic problems can be seen, eg. a signal with a stronger left channel is seen as a shape sloping to the left [\], more right slopes to the right [/], and dead mono is a vertical line [|]., The meter below the scope display indicates the degree of stereo correlation between the channels, a value of +1 means that it is perfectly mono compatible, and -1 and that the channels are in anti-phase (so they will cancel out if mixed)., If someone has better examples, please mail them to me, there are probably tutorials online.

DPM - Digital Peak Meter, Conforming to IEC 268-18:1995 (peak indiciator decay may not be correct)., These are meters as typically seen on digital consoles, HD recorders etc., There are the most efficient in screen realestate and CPU use but look a bit boring ;)

VU - Volume Unit meters, Conforming to BS 6840-17:1991. Real meter is larger., These meters are designed to measure the "volume" of an audio signal, it is not as relevant to digital systems as PPM meters, but is useful if you are interfacing to analogue tape, FM broadcast equipment or want a general idea of the signal volume., The -r flag (set reference level) is usful with these meters as it will allow you to calibrate to your DA converters. The meter is pre-adjusted so that it should allign correctly calibrated DA converters with analogue systems. If you wish to run with 0dBFS = 0dBu then use "-r 20"


PPM - Peak Program level Meters, Approximatly conforming to BS 6840-10. These meters are designed to indicate peak amplitude, as opposed to VU meters which are designed to indicate volume., The scale is correct according to the standard, 4 equates to 0dB, 1 to -12, 7 to +12, and it is linear with decibels., I've never used a real PPM meter, so I don't know if it reacts correctly. Feedback welcome.


a simple waveform viewer for JACK. The waveform is displayed in realtime, so you can always see the signal the instant it comes through JACK's input port.


a smart, fast and accurate toolbox for every composer, performer, recordist, mixer, you name it...

The typical use case is :

You are working on a piece of music at 156 BPM, just because you like it when it pulses. You now feel happy with your composition but want to spice things up with some crazy delays beating as a dotted 8th note. How many milliseconds would you have to set this delay to ?

Well, Qrest has the answer : 144ms > Dls > 0.6.0

Ardour is a digital audio workstation. You can use it to record, edit and mix multi-track audio. You can produce your own CDs, mix video soundtracks, or just experiment with new ideas about music and sound.

Ardour capabilities include: multichannel recording, non-destructive editing with unlimited undo/redo, full automation support, a powerful mixer, unlimited tracks/busses/plugins, timecode synchronization, and hardware control from surfaces like the Mackie Control Universal.


a multichannel hard disk recorder (HDR) and digital audio workstation (DAW). It can be used to control, record, edit and run complex audio setups. One of the most sophisticated liux audio programs, so not good for beginners...

Ardour supports pro-audio interfaces through the ALSA project, which provides high quality, well designed device drivers and API's for audio I/O under Linux. Any interface supported by ALSA can be used with Ardour. This includes the all-digital 26 channel RME Hammerfall, the Midiman Delta 1010 and many others.

Ardour has support for 24 bit samples using floating point internally, non-linear editing with unlimited undo, a user-configurable mixer, MTC master/slave capabilities, MIDI hardware control surface compatibility.

It supports MIDI Machine Control, and so can be controlled from any MMC controller and many modern digital mixers.

Ardour contains a powerful multitrack audio editor/arranger that is completely non-destructive and capable of all standard non-linear editing operations (insert, replace, delete, move, trim, select, cut/copy/paste). The editor has unlimited undo/redo capabilites and can save independent "versions" of a track or an entire piece.

Ardour's editor supports the community-developed LADSPA plugin standard. Arbitrary chains of plugins can be attached to any portion of a track. Every mixer strip can have any number of inputs and outputs, not just mono, stereo or 5.1. An N-way panner is included, with support for various panning models. Pre- and post-fader sends exist, each with their own gain and pan controls. Every mixer strip acts as its own bus, and thus the bus count in Ardour is unlimited.

You can submix any number of strips into another strip.

Ardour's channel capacity is limited only by the number on your audio interface and the ability of your disk subsystem to stream the data back and forth.

JACK (the JACK Audio Connection Kit) is used for all audio I/O, permitting data to be exchanged in perfect samplesync with other applications and/or hardware audio interfaces.

What is destructive are files resulting from capture and recording operations, and explicit changes made through specialized Clip editing (e.g., MIDI Editor).

written in C++ with the Qt4 framework.

Currently the Qtractor project is simply the hobby of one developer. Development was started April 2005, initially as a Qt3 application. Since October 2006, it is officially a Qt4 application.

Qtractor is natively hardwired and exclusive to the JACK Audio Connection Kit infrastructure, and the ALSA sequencer for MIDI, thus currently being a Linux-only application. > Projects > Qtractor > Wiki > Qtractor

I use Reaper live all the time to play backing tracks and then input monitor my guitar with effects on another track. the input monitoring is so darn effective, it’s really up to your machine and interface as to how low you can get your latency down to. I’m using a late 2009 I7 920 based PC with a 6-7 year old EMU 1820M and can get pretty low latency (~6-7ms). REAPER is also my favorite studio DAW too. The takes and comping functions are so much better now The best thing is, the whole development was carried out while listening to the users, on a continuous base! That’s one of the best things in Reaper… pitch envelopes are AWESOME. One thing that always annoyed me about previous versions was that you had to right click + drag just to make a marquee selection. Well now at least there’s a new option in preferences to make Left click + Drag do the same thing. In other words Now you can make it behave like literally Every other program out there (to an extent, anyways). • REAPER is so much more efficient that Live (my other DAW). In REAPER I can run several huge Kontakt instruments and still track with minimal latency. For me REAPER doesn’t replace Live, but it certainly replaces Logic. there is a real time investment required. It DOES do a few basic things differently. The more comfortable you are with integrating keyboard shortcuts into your workflow, the better off you will be. FWIW I found the tutorials at Groove3 really helpful. Also, check out some of the UIs offered in the user forums. RADO v4the bone of the best DAW interfaces I have ever used. There is a feature in Reaper that I really like. It’s the feature that turns on and turns off VST’s right under the M,S buttons. When I’m doing a mixdown of a track I click on those buttons endlessly as if I’m performing and I generating remixes so no two mix downs are ever a like. I know other DAWS can do it but Reaper does it effortlessly on one of the slowest laptops I have and have never had the laptop or hard drive hiccup when performing these mix downs in realtime. First impressions are huge, especially when trying to get users coming from a different DAW. So while Reaper can behave however you’d like, the default settings should be immediately familiar. Another awkward thing is when loading a plug-in, one has to open the FX dialog, then open the load plugin dialog, then find the plugin. Too many steps. I know that it’s configurable, but the average user isn’t going to know how to do that. as with most things in REAPER, you can configure it to work as you wish. I save a Track Template and/or FX chains for each VST and load them by right cicking on the FX button. Or you can keep the FX browser window open and docked, and drag and drop VSTs onto tracks. Guess you know this, but I just wanted to show the uninitiated that there is usually a way to customize REAPER to your requirements. as someone who has used everything out there, and protools since it was in beta, i can tell you reaper is amazing, especially for the price. if you need a basic nuts and bolts daw, this is it. and from what i see in v4, wow….. too bad every friggin studio and post house is avid controlled………… yeah when i have to do large scale sessions, with many inputs and plugs, pt tdm rules. but for 90% of my pro work, reaper would suffice easily….. and i love the pitch and 3d stuff………….. 60 bucks? amazing…

People often mention Reaper as a free VST host, but please note that Reaper is actually commercial software with a 30-day trial period. Although the actual software installation never expires, you should purchase a licence if you use it longer than 30 days (there is however Reaper v0.999 which is still available for free, many thanks to vian for sharing the info in the comments!).

A free, open source software for recording and editing sounds



Audacity multi-track demo, Demonstrating 16 stereo tracks mixing with audacity. This tune is made with two different tunes, Motteke sailor fuku ( Vocal track ) and Hare hare yukai ( Off-vocal track )

Remove Vocals from Mp3s using audacity (Win/Mac/Linux) Free, More Video Tutorials Here Download Audacity To save as mp3 you need to have lame mp3 encoder installed This works with stereo tracks that have the vocals centered, when inverting a track, the waveforms cancel but it may grab more than vocals in some cases. Below are more alternatives. Save to one track at the end. Reduce the audio volume with amplify to make the softest parts disappear then increase it again. This will remove the vocals completely so quit whining about the "reduction". More Info Enable VST in Audacity for More Plugins Audacity Nyquist
