Chord Analyzer

Chord Analyzer is an audio analysis tool that automatically detects guitar chords from your music recordings. Upload an MP3, WAV, OGG, M4A, or FLAC file (up to 50 MB, 15 minutes max) and the tool analyzes the audio to identify chords in time with the lyrics, while also determining the song's key, BPM, and time signature. The results are displayed on a private song page with chord diagrams tailored to your instrument.

Key features include automatic chord detection synchronized with lyrics, key and tempo identification, chord diagrams for multiple instruments, and support for large audio files. The first 60 seconds of analysis is free without requiring an account, and users can get their first full song analyzed free with a no-credit-card-required account.

This tool is ideal for musicians, producers, songwriters, and music learners who want to quickly understand the harmonic structure of recordings, whether analyzing their own demos, covers, or reference tracks for learning purposes.
