Linux

  • Linuxaudio.org is a not-for-profit consortium of libre software projects and artists, companies, institutions, organizations, and hardware vendors using Linux kernel-based systems and allied libre software for audio-related work, with an emphasis on professional tools for the music, production, recording, and broadcast industries.

OSS

ALSA

amixer -c 0 | pcregrep "control"
  • ASIO4ALL - Universal ASIO Driver For WDM Audio

PulseAudio

  • PulseAudio is a sound system for POSIX OSes, meaning that it is 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.
  • pacmd - Reconfigure a PulseAudio sound server during runtime
pacmd dump

JACK

  • JACK is system for handling real-time, low latency audio (and MIDI). It runs on GNU/Linux, Solaris, FreeBSD, OS X and Windows (and can be ported to other POSIX-conformant platforms). 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 also has support for distributing audio processing across a network, both fast & reliable LANs as well as slower, less reliable WANs.

Integration

  • realtimeconfigquickscan - Linux configuration checker for systems to be used for real-time audio. Inspects a linux installation, and makes suggestions for improving realtime/audio performance.

Sessions

  • ladish is a session management system for JACK applications on GNU/Linux. Its aim is to allow you to have many different audio programs running at once, to save their setup, close them down and then easily reload the setup at some other time. ladish doesn't deal with any kind of audio or MIDI data itself; it just runs programs, deals with saving/loading (arbitrary) data and connects JACK ports together. It can also be used to move entire sessions between computers, or post sessions on the Internet for download.

Control

  • Patchage is a modular patch bay for audio and MIDI systems based on Jack and Alsa.
  • JACK Rack is an effects "rack" for the JACK low latency audio API. The rack can be filled with LADSPA effects plugins and can be controlled using the ALSA sequencer. It's phat; it turns your computer into an effects box.
  • cabestan is a small GTK+ program that interfaces with the jack audio connection kit to play, rewind, or fast forward the stream via the jack transport interface.

Video

Processing

  • JAMin is the JACK Audio Connection Kit (JACK) Audio Mastering interface. JAMin is an open source application designed to perform professional audio mastering of stereo input streams. It uses LADSPA for digital signal processing (DSP)

Network

  • Netjack is a Realtime Audio Transport over a generic IP Network. It is fully integrated into JACK. Syncs all Clients to one Soundcard so no resampling or glitches in the whole network. Packet loss is now also handled gracefully. By using the celt codec, its even possible, that single packet losses get masked by the Packet Loss Concealment Code.

Tools

GStreamer

CRAS

  • CRAS: ChromeOS Audio Server - allows for sound to be routed dynamically to newly attached audio-capable monitors (DisplayPort and HDMI), USB webcam, USB speakers, bluetooth headsets, etc., and in a way that requires as little CPU as possible and that adds little or no latency.

Csound is a program that runs on virtually every major hardware platform and Csound supports all operating systems. Most importantly, Csound is open source and Csound is FREE! For years now, Csound has been offering innovative sound designers, composers, and producers a unique and powerful palette with which to create and sculpt innovate and diverse works. Csound is not restricted to any style of music, and has been employed for many years in the creation of classical, pop, techno, ambient, and experimental avant-garde computer music, as well as music for film and television.

CLAM

  • CLAM is a software framework for research and application development on the audio and music domain. It provides means to perform complex audio signal analysis, transformations and synthesis. It also provides a uniform interface to common tasks on audio applications such as accessing audio devices and audio files, thread safe communication with the user interface and DSP algorithms recombination and scaling.

v.001

  • http://001.vade.info/ v.001 is a community driven, open source, modular solution for building easy to (re) use Max/MSP and Jitter patches targeted (but not limited to) visual performers and programmers.

Buzz

  • Buzz is the first ever "easy to use" free modular software based synthesizer. What this means is that the entire system is based on objects, which may be routed in a modular fashion, giving you the freedom to be as creative as you want. For example, if you wish to run 3 Physical Modelling synths and a Drum Machine through 2 seperate Stereo Delays, into a Mixer, through a Compressor and Parameteric EQ, and finally out to your speakers - no problem. Lay down your synths, connect the wires and you're done.

OpenMusic

  • OpenMusic (OM) is a visual programming language based on Lisp. Visual programs are created by asssembling and connecting icons representing functions and data structures. Most programming and operations are performed by dragging an icon from a particular place and dropping it to an other place. Built-in visual control structures (e.g. loops) are provided, that interface with Lisp ones.

DIN Is Noise

  • DIN (DIN Is Noise) is a software musical instrument, uses the computer mouse to pick both the pitch (by moving horizontally) and the volume (by moving vertically) of a sound from an on-screen keyboard that displays the notes of the current scale and a number of microtones in-between. Bezier curves, FM and AM and control other parameters like stereo gater patterns, Delay feedback & volume patterns and Compressor patterns. Users can also create an unlimited number of drones pitched on any microtone and edit them in real-time.

Boodler

  • Boodler is an open-source soundscape tool -- continuous, infinitely varying streams of sound. Boodler is designed to run in the background on a computer, maintaining whatever sound environment you desire. Boodler is extensible, customizable, and modular. Each soundscape is a small piece of Python code -- typically less than a page. A soundscape can incorporate other soundscapes; it can combine other soundscapes, switch between them, fade them in and out. This package comes with many example soundscapes. You can use these, modify them, combine them to arbitrary levels of complexity, or write your own.

Repos

VST

VSTi

LADSPA

LV2

LV2 is a successor of both LADSPA (audio effects) and DSSI (instruments) with some backwards compatibility. The scope of the API more or less equals to the sum of LADSPA and DSSI, not in the last place thanks to its modular design.

DSSI

Formats

MP3

  • MP3 (MPEG-1 or MPEG-2 Audio Layer III) is a patented encoding format for digital audio which uses a form of lossy data compression. It is a common audio format for consumer audio streaming or storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players.

Metadata

AAC

  • Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates.

Ogg

Container format.

Vorbis

FLAC

  • FLAC stands for Free Lossless Audio Codec, an audio format similar to MP3, but lossless, meaning that audio is compressed in FLAC without any loss in quality. This is similar to how Zip works, except with FLAC you will get much better compression because it is designed specifically for audio, and you can play back compressed FLAC files in your favorite player (or your car or home stereo, see supported devices) just like you would an MP3 file. FLAC stands out as the fastest and most widely supported lossless audio codec, and the only one that at once is non-proprietary, is unencumbered by patents, has an open-source reference implementation, has a well documented format and API, and has several other independent implementations.

Opus

  • Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but is also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype's SILK codec and Xiph.Org's CELT codec.

DJing

  • Internet DJ Console is a project started in March 2005 to provide a powerful yet easy to use source-client for individuals interested in streaming live radio shows over the Internet using Shoutcast or Icecast servers. Because of the large number of streaming applications that already existed but did little more than stream a pair of audio channels or a fixed playlist, it was decided that IDJC would be the opposite and simulate audio hardware to cut down the expense of creating a home studio.

Historical

MIDI

OSC

OSC is a content format developed at CNMAT by Adrian Freed and Matt Wright comparable to XML, WDDX, or JSON. It was originally intended for sharing music performance data (gestures, parameters and note sequences) between musical instruments (especially electronic musical instruments such as synthesizers), computers, and other multimedia devices. OSC is often used as an alternative to the 1983 MIDI standard, where higher resolution and a richer musical parameter space is desired. OSC messages are commonly transported across the internet and within home and studio subnets using (UDP/IP, Ethernet). OSC messages between gestural controllers are usually transmitted over serial endpoints of USB by being wrapped in the SLIP protocol.
