Get the chords of a track from an audio file
Submit a recording and get a first draft chart. Read this first: what the analysis actually returns.
What you will get, and what you will not
Better said up front than discovered later. The analysis returns **major and minor** chords. It does not return extensions: a seventh, a ninth or a sus4 present in the recording will come back as a plain chord. The result is a draft to correct, saving you the work of picking it out by ear — not a transcription.
How it works
The recording goes through three stages. The tracks are first separated, to isolate what carries the harmony and set aside drums and vocals. The harmony is then estimated bar by bar, along with tempo and key. Finally a split into sections is proposed, and identical bars grouped.
What you can submit
An audio file, or a link to an online video. The file is the more reliable route: fetching from a link depends on a third-party service that may refuse the request.
Correcting efficiently
Take it in this order. Check the key first: if that is wrong, everything else will be. Then check the split into sections, easier to recognise by ear than the chords. Finish with the doubtful bars, the ones where the chord changes midway — that is where the estimate goes wrong most often.
What it costs
Two analyses per month on the free plan. That counter is shared with photo transcription: two analyses in total, whichever route you take. Unlimited on Pro.
When another route is better
If the song already exists as a chart on a chord site, importing the text will give a better result in less time. If you have the score in front of you, a photo will be more faithful. Audio analysis is for the cases where all you have is the recording.
