Fragment is a real-time collaborative cross-platform audiovisual live coding environment with pixels based image-synth approach to sound synthesis, the sound synthesis is powered by pixels data produced on the graphics card by code.

Fragment can be thought of as an oscillator-bank and filter-bank synthesizer driven by bitmap data.

It has many features making it a bliss to produce any kind of sounds and visuals and is aimed at artists seeking a creative environment with few limitations to experiment with, a programmable noise-of-all-kinds software / sound design tool.

Videos of most features are available on the official YouTube channel

If you have any questions or require help, a documentation and a discussion board is available.

• Real-time, reactive audiovisual live coding environment with GLSL and Processing.js support
• Oscillator-bank and filter-bank spectral synthesizer driven by graphics data
  • Stereophonic
  • Polyphonic
  • Multitimbral
  • 32-bit float images data; provide high dynamic range
• Wide range of instrument types, all driven by pixels data
  • additive, subtractive, spectral, granular, phase modulation, physical modelling, wavetable, bandpass, modal, formant, string synthesis...
  • new instruments can be created live through the Faust language
• Multi-output, ASIO / JACK support, virtual channels with over 30 stereo effects
  • new effects can be created live through the Faust language
• Fully featured list of input data (note : most imported audio is converted as a sonogram using gabor wavelet transform)
  • camera and microphone capture
  • images files
  • audio files
  • videos with basic playback features
  • desktop capture allow to use any kind of programs to drive the synthesizer
  • canvas with brush based drawing
  • Processing.js sketchs
  • graphics data produced live can be imported back
• MIDI in/out support
  • MIDI IN with Multidimensional Polyphonic Expression (MPE) support
  • MIDI OUT with JavaScript scripting
• OSC in/out
• Graphics data recording with WAV export (additive synthesis)
• Anonymous online sessions, no authentifications required, can also work offline or locally
• Distributed sound synthesis, multi-machines/multi-core support (Fragment Audio Server with fas_relay)
• Free, cross-platform, open-source software (Simplified BSD License)

27/03/2021  Fragment 2.0 released, massive client & audio server update

31/12/2017  Subtractive/PM synthesis, audio server update etc. (1.0.3)

19/11/2017  MPE support, enhanced granular synthesis (1.0.2)

 Instructions to run the AppImage (note : must be run into a terminal)

• sudo chmod +x fas.AppImage in a terminal (or allow the file to be executable through file properties)
• launch with ./fas.AppImage command in a terminal

• Web. browser such as Chromium (recommended), Brave, Opera, Safari or Firefox
  • Web. browser should support WebGL 2
  • MIDI compatibility is restricted to a few browsers (Chromium, Brave...)
• Mid-range GPU, Fragment develoment use a GeForce GTX 970
• Mid-range multi-core CPU, a beefy CPU may be needed for some instrument type such as granular synthesis
• MIDI device such as a MIDI keyboard/controller is recommended

Note : Performance and latency may vary with the overall computer load, Fragment is quite latency sensitive.
