Fix BPM Mistakes.
Automatically.
AI-powered analysis catches half-time, double-time, and tricky BPM errors in your DJ collection — with 93% AI detection rate and full dry-run safety before touching your files.
Safe by default: dry-run preview + automatic backups.
Get correct BPM in three easy steps.
Analyze in Your DJ Software
Before checking for octave errors, make sure your tracks have BPM values. Import your music into Traktor, Serato, or rekordbox and run the built-in analysis. This gives each track an initial BPM that our tool will then verify.
Already have an analyzed collection? Skip straight to step 2. Our tool reads your existing library file directly - no need to re-import anything.
Run Analysis
Select a scope — full collection, a playlist, or individual tracks. Multiple AI engines analyze simultaneously. GPU-accelerated when available.
Analysis is read-only - your collection is never modified at this stage. Each engine votes independently, and consensus resolves disagreements.
Review & Fix
Review detected errors in the GUI. Each track shows engine estimates, confidence scores, and the recommended correction. Approve all or cherry-pick.
Dry-run previews changes before any file is modified. Automatic backups created. Optionally export a report before fixing.
