Top 23 Synthesis Open-Source Projects

  • Tone.js

    A Web Audio framework for making interactive music in the browser.

    Project mention: Programmable Synth | | 2022-07-06

    That sounds like it's the issue. Reading this thread it sounds like there is not much that can be done about it.

  • Sonic Pi

    Code. Music. Live.

    Project mention: Dittytoy lets you code generative music with javascript in the browser | | 2022-11-21

    Y'all should check out Sonic Pi!

    Project mention: Wintermute FM is a generative radio station, streaming 24/7 of real-time generated lofi ambient music for human relaxation. Stream: [beta] | | 2022-11-27
  • awesome-livecoding

    All things livecoding

    Project mention: Sonic Pi – The Live Coding Music Synth for Everyone | | 2022-11-07

    Live coding is how I learned to program and I am so glad that this type of computer music performance exists. I am currently doing my PhD on the topic! Programming as a performative act, with its own culture and music sub-genres. For those interested in helping / taking a look, I am currently trying to hack my own live coding environment based on Python asyncio mechanisms: I am a bit shy about it because I am light years behind the level of the projects that are posted on HN and that keep me inspired. I've taught myself how to do this basically by live coding ... a lot, with friends in France! Learning a bit of CS because of music.

  • SOUL

    The SOUL programming language and API (by soul-lang)

    Project mention: Future of audio software development? | | 2022-02-14

    The soul overview gives some compelling reasons. The creator (also of JUCE) was basically predicting that C++ will eventually be phased out for these applications one way or another

  • pyo

    Python DSP module

  • herbie

    Optimize floating-point expressions for accuracy

    Project mention: Someone’s Been Messing with My Subnormals | | 2022-09-06

  • edalize

    An abstraction library for interfacing EDA tools

    Project mention: Compiling Code into Silicon | | 2021-12-07

    This reminds me very much of edalize[1], which does something very similar.
