From audio to chords you can verify.
The analyzer gives you a reviewable draft. Your ears make the final call.
A useful estimate, with the uncertainty visible
Strong fit
Clear major or minor harmony, stable tuning, and separated chord changes.
Needs review
Dense mixes, percussion-heavy passages, key changes, or overlapping instruments.
Not promised
Sevenths, extensions, slash chords, inversions, exact notation, or fixed accuracy.
Use the chord chart as a starting point
Learn a progression by ear
Use the estimated timeline as a starting map, then click each segment and check the original recording yourself.
Sketch a new arrangement
Document the broad harmonic movement of audio you may analyze before rebuilding the idea in your own arrangement.
Mark chord-change times
Export a timestamped TXT chart for rehearsal notes, reference, or a later Studio session.
How to find chords from audio
- 1
Open Chord Finder
Continue to the focused local workspace and choose a rights-cleared audio file from your device.
- 2

Chord Finder FAQ
How does song to chords conversion work?
Choose a permitted recording in the private Song Chord Finder workspace. The local analyzer estimates a timed progression and key, then lets you verify the audio-to-chords result by ear.
What chords can this Chord Finder detect?
The current local analyzer estimates common major and minor triads. It does not claim reliable seventh chords, extensions, slash chords, inversions, or full notation.
Does it find the key of the song?
It returns an estimated major or minor key with a calculated confidence value when the source has a clear tonal center. Modulation, tuning drift, or ambiguous harmony can reduce confidence.
Can I hear where each chord starts?
Yes. After a real analysis succeeds, selecting a chord segment seeks the original local source to that segment start so you can verify it by ear.
How accurate is automatic chord detection?
Accuracy depends on the recording. Clear harmony works best; dense mixes, distortion, extended chords, inversions, tuning drift, percussion, and key changes can reduce accuracy. Treat every result as an estimate.
Is the audio uploaded?
Not for chord detection. The source is decoded and analyzed on this device. Upload happens only if you explicitly choose to save the source and analysis to your private Library and open it in Studio.
How much does Chord Finder cost?
The current on-device chord analysis costs 0 credits and does not require sign-in. Saving and opening the source in Studio is a separate explicit authenticated action.
What can I export?
The current workspace can copy the displayed progression and download a real TXT chart containing the estimated key, timestamps, chord labels, confidence values, and an accuracy disclaimer.
Will the result survive a refresh?
No. The local source and current chord result are browser memory for this task and are cleared by a full refresh unless you explicitly save the analysis to your private Library.
Ready to map the progression?
Choose a source inside the local workspace, run the estimate, and verify each chord against the real audio.
