Identify chords from an audio file

The problem this page solves

You have a recording and need the chord changes without transcribing by ear. Chord Identifier maps the file onto a waveform timeline so you can play along.

The free preview analyzes the first 30 seconds. Premium unlocks the complete song, guitar diagrams, and exports.

How the recognition works

Audio is sent to a chord-recognition model that estimates chord labels over time (for example C, Am, F, G). Results appear as markers on the waveform, not as a printed lead sheet.

Clearer mixes help. Solo guitar or piano usually scores better than a dense live mix with crowd noise.

Limits and accuracy

Recognition can miss fast changes, heavy distortion, or unusual tunings. Treat the output as a starting point and confirm by ear.

Compared with pausing a DAW and guessing on a fretboard, this is faster — it is not a substitute for a human transcription of a complex arrangement.
