CSyn - Cross-Platform Audio Engine for 'C'

Please note that CSyn is currently only available for commercial licensing. For personal music programming please use JSyn.

CSyn is a library of audio synthesis functions that a 'C' programmer can use to add real-time audio to their applications.  CSyn is designed  for games,  music compositions, and other interactive audio applications such as psycho-acoustic experiments.  CSyn is currently being used as the native synthesis engine for JSyn, an audio synthesis API for Java.

Key Features of CSyn

• Efficient CPU based audio synthesis.
• Unit generators such as oscillators, filters, envelopes, etc. can be connected together to create arbitrarily complex sounds.
• An event buffer allow musical events to be played with rock solid timing even on a non-real-time system such as a PC.
• Sample playing unit generators can be used in combination with other synthesis units.
• Multi-segmented envelopes can be used as contour generators, complex LFOs, etc.
• Sample and envelope data can be queued to implement attack and sustain loops, ADSR envelopes, etc.
• Synthesis parameters can be specified in native DSP units, or in natural units such as Hertz.
• A wide variety of synthesis techniques can be implemented including:
• subtractive synthesis using time varying resonant filters,
• granular synthesis using cascaded parabolic envelopes,
• physical modeling,
• sample playback,
• delay based effects such as multi-tap delays and reverberation.

Examples of what can you do with CSyn?

• Create complex continuous sound effects with control over multiple parameters.
• Play musical notes for use in MIDI file players and algorithmic score generators.
• Use reverberation effects to model tunnels, halls, or dungeons.
• Create wind sounds using random modulation of filtered noise.
• Create helicopter sounds using LFO modulation of filtered noise.
• Create water sounds using stochastic synthesis.

License

Licenses for CSyn will soon be available for use in applications such as video games on PC and Macintosh.  CSyn was designed to be portable.  If you would like to have CSyn ported to your custom platform, please let us know.

JSyn Documentation Links

CSyn will eventually be available separately from JSyn. Reading the documentation for JSyn now will give you an advance idea of the capabilities of CSyn.
