Chord Analyzer

Chord Analyzer is an audio analysis tool that automatically detects guitar chords from music recordings and displays them synchronized with lyrics. Users can upload MP3, WAV, OGG, M4A, or FLAC files up to 50 MB and 15 minutes long to receive chord progressions, musical key, tempo (BPM), and time signature information on a private song page.

The tool offers 60 seconds of free chord analysis without requiring an account, and a full first song free with registration (no credit card needed). Results include chord diagrams tailored to the detected key and selected instrument, making it useful for musicians learning songs, transcribing demos, and analyzing rehearsal recordings.

Chord Analyzer is designed for musicians, producers, songwriters, and anyone seeking to quickly identify chord progressions from audio files without manual transcription.
