What does Song Analyzer detect?

It detects BPM (tempo), musical key with Camelot code, chord progression with timestamps, converts melody to MIDI, and separates vocals from instrumentals — all from a single upload.

Is my audio uploaded to a server?

No. All five analyses run entirely in your browser using Web Workers. Your files never leave your device.

What are refined results?

After stem separation completes, MIDI and chord detection re-run on the isolated audio (vocals for MIDI, instrumental for chords) for better accuracy. Results update automatically with a 'Refined with stems' badge.
