The synthio module has been part of CircuitPython since 8.2.0-beta0 and is under development. It can drive up to 12 wavetable oscillators simultaneously (polyphonic synthesis), in stereo, 16 bits of resolution, at adjustable sample rates.
This repo is a document of tips and tricks for using synthio.
EmissionControl2 (EC2) is a standalone interactive real-time application for granular synthesis and sound file granulation. Make new sounds to use in synthesizers, samplers, or other fx-related stuff.
A three-stage deep learning system which can figure out how to imitate a person's voice from as little as five seconds of recorded speech. Speaks with the deepfaked voice in realtime. The sample is used to condition an existing TTS model to sound like someone.

An overview of the OpenRISC architecture and how to get started using it. Briefly talks about synthesizing an FPGA bitstream, setting up a development environment, and either emulating it or running it inside an FPGA. Also covers cross compiling an OS for it.
