Show HN: Web Audio Studio - A Visual Debugger for Web Audio API
Graphs
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 positioning, delay timing, and more -- so you
can better understand what each part of the graph is doing. You can
also insert an AnalyserNode between any two nodes to inspect the
signal at that exact point in the chain. There are around 20
templates (basic oscillator setups, FM/AM synthesis, convolution
reverb, IIR filters, spatial audio, etc.), so you can start from
working examples and modify them instead of building everything
from scratch. Everything runs fully locally in the browser -- no
signup, no backend. The motivation came from working with non-
trivial Web Audio graphs and finding it increasingly difficult to
reason about structure and signal flow once things grow beyond
simple examples. Most tutorials show small snippets, but real
projects quickly become harder to inspect. I wanted something that
stays close to the native Web Audio API while making the runtime
graph visible and inspectable. This is an early alpha and desktop-
only for now. I'd really appreciate feedback -- especially from
people who have used Web Audio API in production or built audio
tools. You can leave comments here, or use the feedback button
inside the app. https://webaudio.studio
