I built a synthesizer based on 3D physicsfree tier, from $99/mo▲512I've been working on the Anukari 3D Physics Synthesizer for a little over two years now. It's one of the earliest virtual instruments to rely on the GPU for audio processing, which has been incredibly challenging and fun. In the end, predictably, the GUI for manipulating the 3D system actually ended up being a lot more work than the physics simulation. So far I am only selling it direct on my website, which seems to be working well. I hope to turn it into a sustainable business, and ideally I'd have enough revenue to hire folks to help with it. So far it's been 99% a solo project, with…

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…

I built k-synth as an experiment to see if a minimalist, K-inspired array language could make sketching waveforms faster and more intuitive than traditional code. I’ve put together a web-based toolkit so you can try the syntax directly in the browser without having to touch a compiler: Live Toolkit: https://octetta.github.io/k-synth/ If you visit the page, here is a quick path to an audio payoff: - Click "patches" and choose dm-bell.ks. - Click "run"—the notebook area will update. Click the waveform to hear the result. - Click the "->0" button below the waveform to copy…
