Ask HN: What audio/sound-related OSS projects can I contribute to?

• score

  99 1,422 9.6 C++

  ossia score, an interactive sequencer for the intermedia arts

  

Happy to introduce you to https://ossia.io there are a lots of tasks open! You can check the projects for the general development axes: https://github.com/ossia/score/projects?query=is%3Aopen ; e.g. Audio, Musicality, Integrations, JACK & Linux integration (some are in Classic projects mode) all have audio-related tasks, some easy, some hard.

Creating new Avendish plug-ins (docs: https://celtera.github.io/avendish/) could also be fairly useful, here's a very basic example one: https://github.com/celtera/avendish/blob/main/examples/Advan...

• HandheldCompanion

  101 1,000 9.8 C#

  ControllerService

I work on an open source application for which were looking with someone who knows how to analyze computer game audio which can then be converted to gamepad controller haptic/vibration feedback. Basically to get rumble support for "old" games that did not natively have this.

Project: Handheld Companion (https://github.com/Valkirie/HandheldCompanion)

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• plugdata

  22 1,294 9.9 C

  Pure Data as a plugin, with a new GUI

  

The Rust audio environment might need help, if you're into that:

https://rust.audio/

Maybe this might be worth a look, too:

https://plugdata.org/

It's a recent attempt to make Pure Data more accessible for less technically inclined users.

• faust

  54 2,408 9.6 C++

  Functional programming language for signal processing and sound synthesis (by grame-cncm)

  

I heard of https://github.com/grame-cncm/faust a while back, probably via HN. It looks interesting and actively maintained, but I didn’t get a chance to play with it. There are many other libraries listed on GitHub awesome lists such as this one: https://github.com/ad-si/awesome-music-production#libraries

• Dplug

  2 477 9.3 D

  Audio plugin framework. VST2/VST3/AU/AAX/LV2 for Linux/macOS/Windows.

  

• codal-microbit-v2

  1 39 8.4 C++

  CODAL target for the micro:bit v2.x series of devices

  

If you're into the embedded/edu/stem/steam space at all, the micro:bit v2 codebase for audio is being integrated more widely this year, and expanding our audio processing components might be a fun, bounded project if you want something smaller, but reasonably high impact?

See https://github.com/lancaster-university/codal-microbit-v2 for the ecosystem, or https://github.com/lancaster-university/codal-core/tree/mast... for the relevant section of the API.

If you're interested, prod me on Github (JohnVidler)

• codal-core

  1 10 7.6 C++

• JUCE

  105 6,096 9.5 C++

  JUCE is an open-source cross-platform C++ application framework for desktop and mobile applications, including VST, VST3, AU, AUv3, LV2 and AAX audio plug-ins.

  

JUCE:

http://juce.com/

Tracktion:

http://tracktion.com/

Both very powerful audio frameworks - JUCE does plugins and audio drivers and low-level DSP, oh my - and Tracktion does all the stuff a DAW needs, on top of JUCE.

There are tons of ways to contribute, from building open source samples, to testing, or even adding functionality. Both dev teams are open to good quality PR's being submitted and both frameworks have excellent communities that will get you started: http://forum.juce.com/

These are cross-platform tools which offer Audio developers an extremely powerful toolset. By contributing to either (or both) frameworks you will be massively contributing to the audio world - so many plugins use JUCE these days!

• pl-10

  1 0 6.5 TypeScript

  Customizable self-hosted audio streaming

  

I’ve been working on some educational/toy projects for self hosting an audio streaming website.

Wasn’t quite ready to put this out there, but it might be on topic.

The first release is decidedly simple but maybe you can see where I’m going with this, and happy to talk about future plans and some other stuff under way

https://github.com/burns-fm/pl-10

Excited to see what else pops up in this thread.

• FXcursion

  2 13 4.3 C

  Guitar processor prototype

  

If you're into embedded stuff, some friends of mine are working on a guitar processor: https://github.com/Predtech4/FXcursion

It's not ready for random contributions just yet I believe (needs a lot of refactoring, plus the hardware isn't finalized yet) but we're open for suggestions!

• DSP.jl

  1 365 8.6 Julia

  Filter design, periodograms, window functions, and other digital signal processing functionality

  

• SBEMU

  8 535 9.4 C

  legacy sound blaster emulation for DOS

• jamulus

  44 968 8.8 C

  Jamulus enables musicians to perform real-time jam sessions over the internet.

  

Jamulus is a very cool project and I was blown away by how jamming over the internet was not just usable but actually enjoyable.
