Music Analyzer

This free music analyzer extracts the musical DNA of any track right in your browser. Drop in a song and it detects the tempo (BPM), themusical key and its Camelot code for harmonic DJ mixing, then profiles the mood, energy, danceability and emotional character. It measures broadcast-standardloudness (LUFS), true peak and dynamic range, draws the harmonic pitch-class (HPCP) chroma wheel, and reports spectral features like brightness and spectral flatness. It can also detect genre and descriptive tags with a neural network (MSD-MusiCNN). Analyze a file or your microphone — everything is computed with the Web Audio API and a custom DSP engine, and there is no file-size limit.
