Analyze DJ Track BPM and Key Online Free

Our DJ track analyzer provides everything you need to prepare tracks for professional DJ performance:

• BPM detection — exact tempo with confidence score and alternative candidates
• Musical key — key and mode (major/minor) with confidence score
• Camelot notation — the Camelot wheel position for harmonic mixing
• Compatible keys — which other Camelot keys will mix harmonically with this track
• Energy envelope — visual representation of the track's energy over time
• Chromagram — pitch class energy distribution for key analysis
• Half/double time — alternative BPM values for cross-genre mixing

Professional DJ software like Rekordbox and Serato provides similar analysis features, but requires software installation and often a subscription. WavinTools provides the core analysis features for free, in your browser:

1. Upload your track — drag and drop an MP3 or WAV file
2. Wait for analysis — BPM and key are detected simultaneously in seconds
3. Review results — check BPM, key, Camelot notation, and compatible keys
4. Plan your mix — use the compatible keys to select your next track
5. Analyze another — repeat for all tracks in your set

• Pre-set preparation — analyze all tracks before a DJ set to plan harmonic progressions
• Live performance — quickly analyze unknown tracks during a set
• Music library organization — tag your entire library with BPM and key information
• Remix preparation — get the exact BPM and key before starting a remix project
