I've been working with 2D spectrograms for a while now while working with Speech recognition. It had always fascinated me how speech and words had such distinct features. Looking at spectrograms is essentially like hearing with your eyes. Over the weekend i built a tool to visualize your own audio into a spectrogram in 3D. I used threeJS with shaders and vanilla JS/Html. Play with it here : https://spectrogram-threejs.vercel.app/ I hope it brings you as much joy as it does for me.

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

I’ve recently released my solo project Audiocube I wanted to make a 3D DAW, where spatial audio, physics, and virtual acoustics are all directly integrated into the engine. This makes it easy to create music in 3D, and experiment with new techniques which aren’t possible in traditional DAWs and plugins. I’d love to get any feedback on this software (Mac/Windows) to make it better. You can download it for free through the website. Thanks, Noah

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…

I'm sharing my project to control 3D models with voice commands and hand gestures: - use voice commands to change interaction mode (drag, rotate, scale, animate) - use hand gestures to control the 3D model - drag/drop to import other models (only GLTF format supported for now) Created using threejs, mediapipe, web speech API, rosebud AI, and Quaternius 3D models Githhub repo: https://github.com/collidingScopes/3d-model-playground Demo: https://xcancel.com/measure_plan/status/1929900748235550912 I'd love to get your feedback! Thank you

I've been going through Cem Yuksel's "Introduction to Computer Graphics" course and thought that writing a volume renderer would be a good way to test my knowledge. It is a common technique used to render 3D medical data. Works by ray marching a specific step size, reading a 3D texture (e.g. MRI data), and calculating opacity values. Code should be easy to get started with for anyone familiar with the JS ecosystem. Questions for the HN community: I spent 20-25% of the entire time just setting up the project and fighting issues with the JavaScript ecosystem. This experience has made me…
