Audio Visualizer – High-Resolution Audio Visualization Tool
I built a free and open-source, high-resolution, real-time audio visualizer on the web. Try it out here: https://audiovisualizer.org The main feature is a very high resolution frequency domain visualizer. It even works in realtime with the microphone. The application also features a synthesizer that can be played with the keyboard or MIDI files and allows for adjustable harmonics and ADSR envelopes. I used React.JS as the framework, P5.JS for rendering the visualizations, the WebAudio API for audio analysis, Meyda.JS and Essentia.JS for feature extraction, Tone.JS for synthesis,…

Web Audio Studio – A Visual Debugger for Web Audio API GraphsMar 2026 · webaudio.studio · ▲64Hi 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…

Talanoa▲340Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
