Open the web version — no install, works on desktop and mobile:
How it works
- Everything runs in your browser. Your recording never leaves your device.
- pYIN pitch tracking and DSP find each note and measure how far it is from pitch, against A4 = 440 Hz (or 442, if that’s how you tune).
- A Go analysis pipeline compiled to WebAssembly — the same engine as the command-line tool.
- Download the result as a self-contained HTML report, JSON, or a Markdown summary.
