Start with BPMandKey.
Detect tempo and musical key instantly, then organize every track by what actually matches. No folder handoff. No duplicate prep. Just material ready for the next creative decision.
BpmAndKey reads the numbers that make music work together. Upload once and get accurate BPM, key, and beat-grid data — for one track or an entire library.
Keep tempo, key, and grid data in one place for every track you've analyzed — a library that gets more useful with every upload.
Every track's tempo and key, locked
Get precise tempo and key readings from the analyzed track — including tempo drift, half/double-time calls, and mode-aware key detection.
Sort, match, and mix with confidence — harmonic-mixing keys, tempo-compatible groupings, and grids that line up in any DAW or DJ software.
- BPM with drift and feel awareness
- Mode-aware key detection
- Beat grid you can trust
- Harmonic-mixing key notation
- Tempo-compatible track groupings
Tempo and key workflows for everyone who mixes music.
BpmAndKey is built for people whose work depends on the numbers being right. One pass over your library and every set, session, and playlist starts from data instead of guesswork.
Wrong BPM ruins a set; wrong key ruins a blend. BpmAndKey reads both from the actual audio, so what you queue up works the way you heard it in your head.
- Keys that actually blend
- Tempo truth, not tag guesses
- Grids that drop on beat
- One library across the suite
Rights-aware creative processing
BpmAndKey analyzes tracks for accurate tempo, key, and beat-grid data — including drift and mode awareness — powered by AFCUT, the shared audio intelligence layer.
From one track, BpmAndKey produces a precise BPM reading, a mode-aware key call, and a usable beat grid. Analyze a library and the data powers sorting, matching, and mixing everywhere you work.

What our users say
“Freeware taggers guess once and hope. BpmAndKey reads tempo drift, half/double-time traps, and modal keys from the actual audio, then keeps the data organized in a library instead of buried in file tags.”
“BPMandKey reads tempo and key in seconds, so every selection is in time and in tune.”
