100+ tracks a minute. BPM, key, and Camelot for everything.
Downloaded tags missing or wrong? Every track gets BPM, key, Camelot code, and loudness, over 100 tracks a minute. BPM 98.9% accurate, key 90.7% on a real library. Free, with no track limit.
Harmonic mixing needs every track's key and BPM. Typing them in is slow, and downloaded tags are often missing or wrong.

No track limit, and keeps working after Premium expires.

Camelot codes are colored around the Camelot wheel, so you see what fits at a glance.

FAQ
What is Camelot?
A way to write keys as a number and a letter, like 8A or 11B. Tracks with the same number, or one step apart, usually mix harmonically. No music theory needed.
How accurate are BPM and key?
Measured on DJ TDope's real library, checked against the BPM and key already in the filenames: BPM is right 98.9% of the time on 884 tracks (within 0.5 BPM). On 885 tracks, key matches the exact Camelot code 90.7% of the time, and 96.6% is harmonically mixable (exact, one step away, or same number with the other letter). Libraries in other genres may score differently.
Does it cost anything?
No. BPM, key, and Camelot are free on every plan, with no track limit. Writing key and BPM to tags needs Premium.
How is Analyze waveforms different from full analysis?
Analyze waveforms only gets BPM, key, and loudness, so it runs about 2.5 times faster. Full analysis adds what is needed for automatic labeling, about 100 tracks per minute. Speed depends on your computer.
Can I preview a track at another BPM?
Yes. Change the tempo or pick a target BPM; the key stays the same, like Master Tempo on a DJ player.
