I originally developed a WASM port of wxWidgets for https://dj.app/. When it came time to open source wxWidgets-wasm, I decided to port another complex app as a test case, and Audacity seemed like the obvious choice. In the process, I also needed to write a new host API for PortAudio for playback and recording in the browser. https://github.com/ahilss/wxWidgets-wasm https://github.com/ahilss/portaudio-wasm https://github.com/ahilss/wavvy

Hi, I'm the author of this little Web Audio toy which does physical modeling synthesis using a simple spring-mass system. My current area of research is in sparse, event-based encodings of musical audio (https://blog.cochlea.xyz/sparse-interpretable-audio-codec-pa...). I'm very interested in decomposing audio signals into a description of the "system" (e.g., room, instrument, vocal tract, etc.) and a sparse "control signal" which describes how and when energy is injected into that system. This toy was a great way to start learning about physical modeling synthesis, which seems…

Hey HN, I just released v4 of my gapless playback library that I first built in 2017 for https://relisten.net. We stream concert recordings, where gapless playback is paramount. It's built from scratch, backed by a rigid state machine (the sole dependency is xstate) and is already running in production over at Relisten. The way it works is by preloading future tracks as raw buffers and scheduling them via the web audio API. It seamlessly transitions between HTML5 and web audio. We've used this technique for the last 9 years and it works fairly well. Occasionally it will blip…

This is part of my journey on pybind11. I wrote a tiny FM Synthesis library in C++ and a Python wrapper for that using pybind11. There is a command-line piano app in the examples directory if you want to play with it. Here is the link: https://github.com/charstorm/koelsynth/tree/main/examples/si... My next target is to attach this to some kind of physics simulation - like a bunch of balls moving around in a box with some internal walls. When the ball hits certain trigger points, it produces the sound.

I'm Sam, I make sample libraries (as FrozenPlain). These sample libraries run inside Floe, my audio plugin for Linux, macOS and Windows. It's designed for musicians, composers and producers - typically people involved with film/TV/game scoring or ambient music. I open-sourced it primarily because I'm very fond of this philosophy and I want to open the door for serving a wider audience than just my own libraries. It's totally free, no sign-ups. You'll need a DAW. To try it: - Download and install Floe: https://floe.audio - Download your choice of free packages:…
