How to find chords
Choose a recording
Open an audio file and select Find chords. The analysis runs in your browser.
Listen along
Read the chords beside the waveform, with the whole song arranged in rows. Click a chord or the waveform to seek.
Save the changes
Export a CSV with chord names and their start and end times.
How accurate are the chords?
Treat them as a starting point. Dense mixes, brief changes and ambiguous harmony can produce wrong labels or timing. Check the result by ear.
Does it follow bars or beats?
The timeline follows elapsed time. Chord changes are estimated from the recording and are not locked to a beat or bar grid.
Why is there a model download?
Musiclet downloads the analysis files to run on your device. They are reused while your browser keeps its cache. Check progress in Models at the top of the page.
Which files can I use?
MP3, WAV, M4A and other audio formats your browser can decode. Support varies by browser and codec. Your audio is processed on your device and is not uploaded.
