Chord Analyzer

Chord Analyzer is a web-based tool that listens to your audio recordings and automatically detects and transcribes the guitar chords in real-time, synchronized with the lyrics. Simply upload an MP3, WAV, OGG, M4A, or FLAC file (up to 50 MB, 15 minutes max) and get back a complete analysis including chord progressions, musical key, BPM, and time signature.

The tool provides detailed chord diagrams for each chord found in your song, making it easy for musicians to learn, transcribe, and share their music. Whether you're working with your own demos, rehearsal recordings, or covers you have permission to analyze, Chord Analyzer streamlines the transcription process that would typically take hours to do manually.

Designed for musicians, songwriters, producers, and music students, Chord Analyzer offers a free tier allowing 60 seconds of analysis without an account, and the first full song free with registration (no credit card required). It's perfect for anyone who wants to quickly understand the harmonic structure of their recordings.
