Web Audio Studio

Alex Griss looked at the Web Audio API—one of the most powerful but notoriously confusing browser APIs out there—and realized developers were basically flying blind. They'd write connect() calls, hit run, and hope for the best. No visual feedback, no way to see what's actually happening in the signal chain. So he built Web Audio Studio, a browser-based visual debugger that turns your code into an interactive graph you can actually see, touch, and hear.

Write your Web Audio code, hit run, and boom—you've got a live node graph showing every oscillator, filter, gain node, and delay in your pipeline. Click any node to see its waveform, filter response, frequency spectrum, or compressor curve. Grab any knob and twist it while the audio plays. The best part? You can drop an analyser anywhere in the chain to inspect the signal at that exact point. Twenty templates included—from basic sine waves to FM synthesis, convolution reverb, and HRTF spatial audio. Everything runs 100% local in your browser. No signup, no backend, no friction.

The Web Audio API powers everything from music production apps to game audio to real-time communication tools, and it's been around for years—but debugging it has always been a nightmare of console.logs and mental gymnastics. Web Audio Studio finally makes it visible. If you've ever struggled to understand why your filter isn't working or where your audio is getting clipped, this is the tool you didn't know you needed. It's free, it's open, and it's exactly the kind of tool that makes a complex API actually approachable.
