DawDreamer is an audio-processing Python framework supporting core DAW features and beyond:

• Composing graphs of multi-channel audio processors
• Audio playback
• VST instruments and effects (with UI editing and state loading/saving)
• FAUST effects and polyphonic instruments
• Time-stretching and looping, optionally according to Ableton Live warp markers
• Pitch-warping
• Parameter automation at audio-rate and at pulses-per-quarter-note
• Parameter automation saving in absolute audio-rate time
• MIDI playback in absolute time and PPQN time
• MIDI file export in absolute time
• Rendering and saving multiple processors simultaneously
• Support for the Faust Box and Signal APIs
• Transpiling Faust code to JAX/Flax and other target languages (C++, Rust, Wasm, etc.)
• Machine learning experiments with QDax
• Multiprocessing support
• Full support on macOS, Windows, Linux, Google Colab, and Ubuntu Dockerfile

DawDreamer’s foundation is JUCE, with a user-friendly Python interface thanks to pybind11. DawDreamer evolved from an earlier VSTi audio “renderer”, RenderMan.
