Chord Detector

Chord Detector is an audio analysis tool that automatically identifies and extracts guitar chords from any music recording. Simply upload an MP3, WAV, OGG, M4A, or FLAC file (up to 50 MB, 15 minutes long) and the analyzer will detect the chords in time with the song, displaying them alongside lyrics along with additional metadata like key, tempo (BPM), and time signature.

The tool offers a generous free tier allowing users to analyze the first 60 seconds of any recording without creating an account, or unlock full song analysis with a free account (no credit card required). The results are presented on a private song page with chord diagrams tailored to your chosen instrument.

Perfect for musicians, songwriters, music students, and anyone looking to transcribe or learn songs from their own recordings or existing audio files they have permission to analyze.
