TuneKey

Detect musical key, tempo, and time signature from any audio file

Audio & MusicFree

TuneKey analyzes audio files to determine musical key, tempo in BPM, time signature, and key changes throughout the track with timestamp markers. The tool handles live recordings with tempo drift, tracks with key modulations, and complex meters including odd time signatures and polyrhythmic patterns. DJs use it for harmonic mixing preparation, music librarians for catalog metadata enrichment, and producers for matching sample banks to project tempos and keys.
