What key is my song in?
We analyze the track's chroma (pitch-class) profile against major and minor key templates and return the best match. E.g. "A minor". Plus its Camelot wheel code (8A, 9B, …) for DJ harmonic mixing.
How is the BPM detected?
We run beat tracking on the audio and report the tempo in beats per minute. Works on any MP3, WAV, M4A, or FLAC.
