HSynth is a purely functional library for audio synthesis. Its main features are

• A arrow-based DSL for creating and composing audio signals
• Optimization of audio signals with the causal commutative arrows technique [1]
• Support for MIDI
• Plotting of audio signals

Getting Started

• The requirements to run HSynth programs is the audio server jack2.

  git clone github.com/svenkeidel/hsynth2.git
  cd hsynth2
  
  cabal sandbox init
  cabal configure -fexamples -fjack
  cabal install
  
  # Start the jack audio server
  jack_control start
  
  # Start the audio example
  ./dist/build/example-jack/example-jack
  
  

Roadmap

• Creating a nice community that invents and shares new instruments
• Making HSynth a great learning resource for digital audio synthesis
