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 HN, I’ve been working on a browser-based tool for exploring and debugging Web Audio API graphs. Web Audio Studio lets you write real Web Audio API code, run it, and see the runtime graph it produces as an interactive visual representation. Instead of mentally tracking connect() calls, you can inspect the actual structure of the graph, follow signal flow, and tweak parameters while the audio is playing. It includes built-in visualizations for common node types — waveforms, filter responses, analyser time and frequency views, compressor transfer curves, waveshaper distortion, spatial…

By and large, using the web is a visual experience. This is in terrible contrast to mobile apps, which interact with three of our human senses (sight, sound, and touch, through haptic feedback). I just released a library to make it easy to add sound to your React app, and I make the case that you sh

Hey HN. I built this quick and dirty component to render audio waveforms using WebGPU. I just published it to NPM. It's the first time I use WebGPU and it's been a while since I write shaders. Feedback is very welcome! GitHub: https://github.com/mrkev/webgpu-waveform Examples: https://aykev.dev/webgpu-waveform

Hi HN, Last time I showed free-music-demixer, which people seemed to enjoy. It was a static website with a Javascript + WASM module to perform music demixing (or music source separation) using an AI model UMX-L (Open-Unmix) running client-side in the browser. Since then, I have overhauled the project and made several improvements: - The demixing/separation quality is higher now, since I implemented the missing post-processing step - Memory usage is lower now by performing a custom segmented inference with a streaming LSTM, which should allow larger tracks (or, dare I say,…

I vibe-coded a complete React rewrite of my multi-track audio editor with Claude. Waveform Playlist v5 started as a "let's see how far AI can take this" experiment. The original was vanilla JS (~8 years old). The new version is React + Tone.js with proper TypeScript, tree-shaking, and a modular package structure. What we built: canvas waveforms, drag-and-drop clip editing, 20+ Tone.js effects, AudioWorklet recording, WAV export, annotations, theming. Demos: https://naomiaro.github.io/waveform-playlist/examples/stem-tracks GitHub:…

Hey HN, I’m an ex-Google engineer trying to get back into music production. I needed a way to sequence my hardware synths using AI contexts without constantly switching windows, so I built this. It runs entirely in the browser using WebMIDI. No login required. It connects to your local MIDI devices (if you're on Chrome/Edge) and lets you generate patterns. Tech stack: [React / WebMIDI API / etc]. Link: www.simplychris.ai/droplets Code is a bit messy, but it works. Feedback welcome.
