Overtone: Open Source Audio Synthesis

An open source audio synthesis and signal processing library for Clojure, enabling real-time sound generation and manipulation through a functional programming approach.

What is Overtone?

Overtone is an open source audio synthesis and signal processing library for the Clojure programming language. It allows developers to leverage the power of functional programming to create and manipulate audio in real time.

Some key features of Overtone include:

  • An intuitive API for generating and processing sound using basic waveforms like sine waves, sawtooth waves, square waves, and noise.
  • Support for modifying sounds by changing parameters like frequency, amplitude, pulse width, etc. in real time.
  • A large collection of audio effects like reverb, distortion, filtering, delay, and more.
  • Tools for sequencing musical patterns and phrases algorithmically.
  • Flexible audio routing to mix and direct sound to different destinations.
  • Compatibility with many external MIDI and OSC controllers.
  • Simple integration with Clojure web frameworks.

Overtone makes it easy for Clojure developers to build creative audio applications without needing to know the intricate details of audio programming. From games and interactive art installations to synthesizers and audio effects, Overtone provides the building blocks to make an almost endless variety of audio experiences.
