Chord Analyzer

Chord Analyzer is an audio analysis tool that automatically detects and identifies guitar chords from music recordings. Upload an MP3, WAV, OGG, M4A, or FLAC file and the service analyzes the audio to extract chord progressions, timing, musical key, BPM, and time signature, displaying results synchronized with song lyrics on a private song page.

The tool supports tracks up to 15 minutes long and 50 MB in size. Users can analyze the first 60 seconds of any recording without creating an account, and get a full song analysis free with a no-credit-card-required account. The service provides chord diagrams customized for your instrument choice.

Ideal for musicians, songwriters, music students, and audio engineers who want to transcribe chords from recordings, create lead sheets, or learn songs by ear without manual transcription.
