MIDI

  • https://en.wikipedia.org/wiki/MIDI_Machine_Control - MMC, a subset of the MIDI specification, provides specific commands for controlling recording equipment such as multi-track recorders. MMC messages can be sent along a standard MIDI cable for remote control of such functions as Play, Fast Forward, Rewind, Stop, Pause, and Record. These are "System Exclusive" (SysEx) messages, specifically Real Time Universal SysEx messages.
  • Linux pSeudo MIDI Input - These simple user-space drivers support using certain homemade, repurposed, or commercial devices as MIDI controllers on Linux, even though the devices themselves are not capable of generating MIDI messages; this does not include things like MIDI-over-serial or PIC based projects, which are true MIDI devices.




  • QwertyKeyboardMidi is a Win32 C++ project that allows you to use your QWERTY keyboard as a MIDI controller. When coupled with MIDI Yoke it allows you to use the keyboard to control software running locally, such as Cubase or Logic.

OSC

  • http://en.wikipedia.org/wiki/Open_Sound_Control - 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.

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.

AMR

Vinyl

CD

Playlists

MOD

  • https://en.wikipedia.org/wiki/MOD_(file_format) - a computer file format used primarily to represent music, and was the first module file format. MOD files use the “.MOD” file extension, except on the Amiga where the original trackers instead use a “mod.” prefix scheme, e.g. “mod.echoing”. A MOD file contains a set of instruments in the form of samples, a number of patterns indicating how and when the samples are to be played, and a list of what patterns to play in what order.
  • https://en.wikipedia.org/wiki/XM_(file_format) - standing for "extended module", is an audio file type introduced by Triton's FastTracker 2. XM introduced multisampling-capable instruments with volume and panning envelopes, and basic pattern compression. It also expanded the available effect commands and channels, added 16-bit sample support, and offered an alternative frequency table for portamentos. XM is a common format for many chiptunes.
  • UADE plays old Amiga tunes through UAE emulation and cloned m68k-assembler Eagleplayer API.

Linux

"there are many good reasons to consider Linux [for pro audio]: low- or no-cost software; a high-performance sound system; great audio routing; powerful sound synthesis; high-quality score notation; it's extremely customisable; more of your CPU power may be used for audio processing; it avoids many patent/license restriction pitfalls; it avoids costly tie-ins to specific product ranges; software may be (legally) modified to suit your individual needs; modular software allows you to configure your software studio the way that you want; and it's driven by passion before profit. [9]

Audio systems

In a Unix-like operating system, a sound server mixes different data streams and sends out a single unified audio to an output device. The mixing is usually done by software, or by hardware if there is a supported sound card.

The "sound stack" can be visualized as follows, with programs in the upper layers calling elements in the lower layers:

  • Applications (e.g. mp3 player, web video)
  • Sound server (e.g. aRts, ESD, JACK, PulseAudio)
  • Sound subsystem (described as kernel modules or drivers; e.g. OSS, ALSA)
  • Operating system kernel (e.g. Linux, Unix)

"If we were drawing the [internet] OSI model used to describe the networking framework that connects your machine to every other machine on the network, we'd find clear strata, each with its own domain of processes and functionality. There's very little overlap in layers, and you certainly don't find end-user processes in layer seven messing with the electrical impulses of the raw bitstreams in layer one.

"Yet this is exactly what can happen with the Linux audio framework. There isn't even a clearly defined bottom level, with several audio technologies messing around with the kernel and your hardware independently. Linux's audio architecture is more like the layers of the Earth's crust than the network model, with lower levels occasionally erupting on to the surface, causing confusion and distress, and upper layers moving to displace the underlying technology that was originally hidden."

"ALSA itself has a kernel level stack and a higher API for programmers to use, mixing drivers and hardware properties with the ability to play back surround sound or an MP3 codec. Most distributions stick PulseAudio and GStreamer on top[,] ... The deeper the layer, the closer to the hardware it is." [10]

  • 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.

Ubuntu Studio

Arch Linux

  • ArchAudio - the Arch Linux Pro Audio community! From offering a third-party package repository to debating recording techniques to discussing FFT, we aim to be a central point for everything related to working with audio on Arch Linux.

Sound systems

OSS

Old.

The API is designed to use the traditional Unix framework of open(), read(), write(), and ioctl(), via special devices. For instance, the default device for sound input and output is /dev/dsp. Examples using the shell: 

cat /dev/random > /dev/dsp
  # plays white noise through the speaker

cat /dev/dsp > a.a
  # reads data from the microphone and copies it to file a.a

ALSA

"ALSA is responsible for translating your audio hardware's capabilities into a software API that the rest of your system uses to manipulate sound. It was designed to tackle many of the shortcomings of OSS (and most other sound drivers at the time), the most notable of which was that only one application could access the hardware at a time. This is why a software component in ALSA needs to manages audio requests and understand your hardware's capabilities.

"ALSA was designed to replace OSS. However, OSS isn't really dead, thanks to a compatibility layer in ALSA designed to enable older, OSS-only applications to run. It's easiest to think of ALSA as the device driver layer of the Linux sound system. Your audio hardware needs a corresponding kernel module, prefixed with snd_, and this needs to be loaded and running for anything to happen. This is why you need an ALSA kernel driver for any sound to be heard on your system, and why your laptop was mute for so long before someone thought of creating a driver for it. Fortunately, most distros will configure your devices and modules automatically. [11]

Configuration
  • http://www.alsa-project.org/main/index.php/Asoundrc - Neither the user-side .asoundrc nor the asound.conf configuration files are required for ALSA to work properly. Most applications will work without them. These files are used to allow extra functionality, such as routing and sample-rate conversion, through the alsa-lib layer.

The keyword default is defined in the ALSA lib API and will always access hw:0,0 — the default device on the default soundcard. Specifying the !default name supersedes the one defined in the ALSA lib API. 

pcm.NAME { 
	type hw               # Kernel PCM 
	card INT/STR          # Card name or number
  	[device] INT          # Device number (default 0)     
	[subdevice] INT       # Subdevice number, -1 first available (default -1)
	mmap_emulation BOOL   # enable mmap emulation for ro/wo devices
}


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.
  • pactl - Control a running PulseAudio sound server
  • pacmd - Reconfigure a PulseAudio sound server during runtime

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.
  • http://aj-snapshot.sourceforge.net/ Aj-snapshot is a small program that can be used to make snapshots of the connections made between JACK and/or ALSA clients. Because JACK can provide both audio and MIDI support to programs, aj-snapshot can store both types of connections for JACK. ALSA, on the other hand, only provides routing facilities for MIDI clients. You can also run aj-snapshot in daemon mode if you want to have your connections continually restored.
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.
  • Cadence is a set of tools useful for audio production. Cadence itself is also an application (the main one), which this page will document. There are other applications that are part of the Cadence suite, they are usually named as the "Cadence tools". They are: Catarina, Catia, Claudia
    • Cadence controls and monitors various Linux sound systems as well as audio-related system settings
cadence --minimized
  • Claudia-Launcher is a multimedia application launcher with LADISH support. It searches for installed packages (not binaries), and displays the respective content as a launcher. The content is got through an hardcoded database, created and/or modified to suit the target distribution.
Video

  • Xjadeo is a software video player that displays a video-clip in sync with an external time source (MTC, LTC, JACK-transport). Xjadeo is useful in soundtrack composition, video monitoring or any task that requires to synchronizing movie frames with external events.
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.

  • SoundConverter is the leading audio file converter for the GNOME Desktop. It reads anything GStreamer can read (Ogg Vorbis, AAC, MP3, FLAC, WAV, AVI, MPEG, MOV, M4A, AC3, DTS, ALAC, MPC, Shorten, APE, SID, MOD, XM, S3M, etc...), and writes to Opus, Ogg Vorbis, FLAC, WAV, AAC, and MP3 files, or use any GNOME Audio Profile.
  • olaboola - cyber-shamanic noise-maker. oolaboola is a digital DJ tool. It allows you to mix .wav files in real-time modifying their rate of play, levels etc. Various facets of its behavior can be controlled via an rc file, environment variables, and command-line options. Settings provided by more than one of those override each other in that same order.

SoX

  • SoX - Sound eXchange, the Swiss Army knife of sound processing programs. SoX is a cross-platform (Windows, Linux, MacOS X, etc.) command line utility that can convert various formats of computer audio files in to other formats.

  • SoundConverter is the leading audio file converter for the GNOME Desktop. It reads anything GStreamer can read (Ogg Vorbis, AAC, MP3, FLAC, WAV, AVI, MPEG, MOV, M4A, AC3, DTS, ALAC, MPC, Shorten, APE, SID, MOD, XM, S3M, etc...), and writes to Opus, Ogg Vorbis, FLAC, WAV, AAC, and MP3 files, or use any GNOME Audio Profile.
  • FreqTweak is a tool for FFT-based realtime audio spectral manipulation and display. It provides several algorithms for processing audio data in the frequency domain and a highly interactive GUI to manipulate the associated filters for each. It also provides high-resolution spectral displays in the form of scrolling-raster spectrograms and energy vs frequency plots displaying both pre- and post-processed spectra.

Ecasound

  • Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package.

Secret Rabbit Code

  • Secret Rabbit Code (aka libsamplerate) is a Sample Rate Converter for audio. One example of where such a thing would be useful is converting audio from the CD sample rate of 44.1kHz to the 48kHz sample rate used by DAT players. SRC is capable of arbitrary and time varying conversions ; from downsampling by a factor of 256 to upsampling by the same factor. Arbitrary in this case means that the ratio of input and output sample rates can be an irrational number. The conversion ratio can also vary with time for speeding up and slowing down effects.

SRC provides a small set of converters to allow quality to be traded off against computation cost. The current best converter provides a signal-to-noise ratio of 145dB with -3dB passband extending from DC to 96% of the theoretical best bandwidth for a given pair of input and output sample rates. Since the library has few dependencies beyond that provided by the standard C library, it should compile and work on just about any operating system. It is known to work on Linux, MacOSX, Win32 and Solaris. With some relatively minor hacking it should also be relatively easy to port it to embedded systems and digital signal processors.

Trackers

  • https://en.wikipedia.org/wiki/Music_tracker - (usually referred to simply as trackers) are a type of music sequencer software used to create music. They represent music tracks as an arrangement of discrete musical notes positioned in one of several channels, at discrete chronological positions on a timeline. The file format used for saving songs is called a module file.

A music tracker's musical interface is traditionally numeric: both notes and parameter changes, effects and other commands are entered with the keyboard into a grid of fixed time slots as codes consisting of letters, numbers and hexadecimal digits.[1] Separate patterns have independent timelines; a complete song consists of a master list of repeated and concatenated patterns.

Later trackers departed from module file limitations and advantages, adding other options both to the sound synthesis (hosting generic synthesizers and effects or MIDI output) and to the sequencing (MIDI input and recording), effectively becoming general purpose sequencers with a different user interface.

Software

  • OpenMPT (short hand for Open ModPlug Tracker), a popular tracker software for Windows.

  • Buzztrax aims to be a music studio that allows one to compose songs using only a computer with a soundcard. If you’ve used tracker programs like FastTracker, Impulse Tracker, or the original AMIGA SoundTracker, that will give you an idea of how one can sequence music in Buzztrax. The Buzztrax editor uses a similar concept, where a song consists of a sequence with tracks and in each track one uses patterns with events (musical notes and control changes). In contrast to other Tracker programs, tracks are not simply sample players: a user can make a song using an arrangment of virtual audio plugins that are linked together to create different effects. Each of these machines can be controlled realtime or via patterns in the sequencer.

Audio programming

  • https://en.wikipedia.org/wiki/Comparison_of_audio_synthesis_environments - typically consist of an audio programming language (which may be graphical) and a user environment to design/run the language in. Although many of these environments are comparable in their abilities to produce high-quality audio, their differences and specialties are what draw users to a particular platform. This article compares noteworthy audio synthesis environments, and enumerates basic issues associated with their use.


MUSIC-N

  • https://en.wikipedia.org/wiki/MUSIC-N - refers to a family of computer music programs and programming languages descended from or influenced by MUSIC, a program written by Max Mathews in 1957 at Bell Labs. MUSIC was the first computer program for generating digital audio waveforms through direct synthesis. It was one of the first programs for making music (in actuality, sound) on a digital computer, and was certainly the first program to gain wide acceptance in the music research community as viable for that task.

The world's first computer-controlled music was generated in Australia by programmer Geoff Hill on the CSIRAC computer which was designed and built by Trevor Pearcey and Maston Beard. However, CSIRAC produced sound by sending raw pulses to the speaker, it did not produce standard digital audio with PCM samples, like the MUSIC-series of programs.

Less obviously, MUSIC can be seen as the parent program for: RTSKED (a later RealTime Scheduling language by Max Mathews), Max/MSP Pure Data, AudioMulch, SuperCollider, JSyn, Common Lisp Music, ChucK, or any other computer synthesis language that relies on a modular system (e.g. Reaktor).

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.


SuperCollider

  • SuperCollider is an environment and programming language for real time audio synthesis and algorithmic composition. It provides an interpreted object-oriented language which functions as a network client to a state of the art, realtime sound synthesis server.

Overtone

  • Overtone is an open source audio environment being created to explore musical ideas from synthesis and sampling to instrument building, live-coding and collaborative jamming. We use the SuperCollider synth server as the audio engine, with Clojure being used to develop the APIs and the application. Synthesizers, effects, analyzers and musical generators can be programmed in Clojure.

Csound

  • Csound is the "ultimate" software synthesizer. Csound is an incredibly powerful signal processor. 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!

JUCE

  • https://en.wikipedia.org/wiki/JUCE - Like many other frameworks (e.g., Qt, wxWidgets, GTK+, etc.), JUCE contains classes providing a range of functionality that covers user-interface elements, graphics, audio, XML and JSON parsing, networking, cryptography, multi-threading, an integrated interpreter that mimics ECMAScript's syntax, and various other commonly used features. Application developers needing several third-party libraries may thus be able to consolidate and use only the JUCE library, or at least reduce the number of third-party libraries they use. In this, the original inspiration was Java's JDK, and JUCE was intended to be "something similar for C++".

A notable feature of JUCE when compared to other similar frameworks is its large set of audio functionality; this is because JUCE was originally developed as a framework for Tracktion, an audio sequencer, before being split off into a standalone product. JUCE has support for audio devices (such as CoreAudio, ASIO, ALSA, JACK, WASAPI, DirectSound) and MIDI playback, polyphonic synthesizers, built-in readers for common audio file formats (such as WAV, AIFF, FLAC, MP3 and Vorbis), as well as wrappers for building various types of audio plugin, such as VST effects and instruments. This has led to its widespread use in the audio development community.[3]

JUCE comes with wrapper classes for building audio and browser plugins. When building an audio plugin, a single binary is produced that supports multiple plugin formats (VST & VST3, RTAS, AAX, Audio Units). Since all the platform and format-specific code is contained in the wrapper, a user can build Mac and Windows VST/VST3/RTAS/AAX/AUs from a single codebase.

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.

  • Suil is a lightweight C library for loading and wrapping LV2 plugin UIs.

MIDI

  • a2jmidid is daemon for exposing legacy ALSA sequencer applications in JACK MIDI system.
  • jack-keyboard is a virtual MIDI keyboard - a program that allows you to send JACK MIDI events (play ;-) using your PC keyboard. It's somewhat similar to vkeybd, except it uses JACK MIDI instead of ALSA, and the default keyboard mapping is much better - it uses the same layout as trackers (like Impulse Tracker) did, so you have two and half octaves under your fingers.
  • TiMidity++ is a software synthesizer. It can play MIDI files by converting them into PCM waveform data; give it a MIDI data along with digital instrument data files, then it synthesizes them in real-time, and plays. It can not only play sounds, but also can save the generated waveforms into hard disks as various audio file formats.
  • Zweeger is a modular extended MIDI filter and generator. It works as a standalone tool or as a VST effect. It can be placed between any MIDI input, such as keyboards, and any tool that can be controlled by MIDI messages (effects, samplers, hardware, software...) It can also work without any input as a "simple" generator. Zweeger is composed of various elements, such as LFO, envelops, random curves, delays, note generators, ... All of them can be chained in various ways, synchronized on the tempo.
  • Aria Maestosa is an open-source (GPL) midi sequencer/editor. It lets you compose, edit and play midi files with a few clicks in a user-friendly interface offering score, keyboard, guitar, drum and controller views. Aria Maestosa runs on Mac OS X, Windows and Linux/Unix.


  • MIDIUtil is a pure Python library that allows one to write muti-track Musical Instrument Digital Interface (MIDI) files from within Python programs. It is object-oriented and allows one to create and write these files with a minimum of fuss.
  • Virtual MIDI Piano Keyboard is 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.
  • arpage - MIDI Arpeggiator w/ JACK Tempo Sync. Alpha status. Source tarball for alpha 0.3.3 release, and SVN access are available.
  • hypercyclic is an LFO-driven MIDI arpeggiator, gate effect and step sequencer for mangling sustained MIDI input chords, the output of which can then drive other MIDI instruments

Looping

  • SooperLooper is a live looping sampler capable of immediate loop recording, overdubbing, multiplying, reversing and more. It allows for multiple simultaneous multi-channel loops limited only by your computer's available memory. The application is a standalone JACK client with an engine controllable via OSC and MIDI. It also includes a GUI which communicates with the engine via OSC (even over a network) for user-friendly control on a desktop. However, this kind of live performance looping tool is most effectively used via hardware (midi footpedals, etc) and the engine can be run standalone on a computer without a monitor.
  • Luppp is a music creation tool, intended for live use. The focus is on real time processing and a fast intuitive workflow. With extensive MIDI mapping support, you can get looping just how you like!
  • kluppe is a loop-player and recorder, designed for live use. kluppe is open source. kluppe does not sound nor look like microsofttm excel#!&© kluppe is the austrian word for clip or peg and sounds even crazier if you loop it.
  • Freewheeling is a new way to be In The Muse-ical Moment. It's a live looping instrument that returns us to the joy of making music spontaneously.
  • Giada is a free, minimal, hardcore audio tool for DJs, live performers and electronic musicians. How does it work? Just pick up your channel, fill it with samples or MIDI events and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler or yet as a plugin/effect host. Giada aims to be a compact and portable virtual device for Linux, Mac OS X and Windows for production use and live sets.
  • LoopDub - a cross-platform audio application for live loop manipulation.
  • Smasher - Cross-platform audio loop slicer designed to create sliced loops from WAV, MP3, FLAC or AIFF files in seconds without a sequencer. Effects include filter sweeps, phasing, flanging, delay, and distortion.
  • Cyclone is a music application for GNU/Linux that allows users to manipulate loops in various ways. It works with professional audio formats like .wav .aif .flac, and professional audio environment (Jack Audio Connection Kit).
  • Tranches is a midi-controlled multi-(inputs/outputs) live beat repeat/rearrange/redirect tool !!! It works on Gnu/Linux with the Jack sound server. There's a command-line and a gui version. It is released under the GNU General Public Licence.

  • DJPlay - aims to be a high class live DJing application for Linux. old.

Radio

  • 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.
  • Rivendell - a complete radio broadcast automation solution, with facilities for the acquisition, management, scheduling and playout of audio content. It has all of the features one would expect in a modern, fully-fledged radio automation system, including support for both PCM and MPEG audio encoding, full voicetracking and log customization as well as support for a wide variety of third party software and hardware. As a robust, functionally complete digital audio system for broadcast radio applications, Rivendell uses industry standard components like the GNU/Linux Operating System, the AudioScience HPI Driver Architecture and the MySQL Database Engine. Rivendell is available under the GNU Public License.

Vinyl

  • xwax is an open-source Digital Vinyl System (DVS) for Linux. It allows DJs and turntablists to playback digital audio files (MP3, Ogg Vorbis, FLAC, AAC and more), controlled using a normal pair of turntables via timecoded vinyls. It's designed for both beat mixing and scratch mixing. Needle drops, pitch changes, scratching, spinbacks and rewinds are all supported, and feel just like the audio is pressed onto the vinyl itself. The focus is on an accurate vinyl feel which is efficient, stable and fast.
  • Digital-Scratch is a software that analyzes motions (rotation speed and direction) of a vinyl disc played by a turntable. It also provides a nice and simple player that play your favorite tracks allowing you to mix as you would do it with regular records.
  • terminatorX - realtime audio synthesizer, allows “scratching” on digitally sampled audio data (*.wav, *.au, *.ogg, *.mp3, etc.) the way hiphop-DJs scratch on vinyl records. It features multiple turntables, realtime effects (buit-in as well as LADSPA plugin effects), a sequencer and MIDI interface – all accessible through an easy-to-use gtk+ GUI.

Liquidsoap

  • http://liquidsoap.fm/ Liquidsoap is a powerful and flexible language for describing your streams. It offers a rich collection of operators that you can combine at will, giving you more power than you need for creating or transforming streams. But liquidsoap is still very light and easy to use, in the Unix tradition of simple strong components working together. A swiss-army knife for multimedia streaming, notably used for netradios and webtvs. It has tons of features, it's free and it's open-source!

  • Shairport Sync is an AirPlay audio player -- it plays audio streamed from iTunes, iOS devices and third-party AirPlay sources such as ForkedDaapd and others. Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible without difficulty. (Hence the name Shairport Sync, BTW.)
