BPM Delay Calculator
Calculate precise delay times in milliseconds for any BPM, including dotted and triplet 1/4, 1/8, and 1/16 note values.
Bars to Time Calculator
Convert bars to an exact duration. Find out how long 16, 32, or 64 bars last at your track's tempo, in seconds and minutes.
Tap Tempo
Tap along to any song to find its BPM. Works with mouse clicks or the keyboard - ideal for quickly reading a track's tempo by ear.
Camelot Wheel Calculator
Find harmonically compatible keys for DJ mixing. Click any Camelot key (1A-12B) to see every key it blends with, plus a full 24-key chart.
BPM Transition Helper

Detect the musical key, Camelot code, and BPM of any song. Drop in an audio file and it's analysed privately in your browser - no upload, no software, no account.
Rhythm Test
How accurate is your internal metronome? Tap along, keep the beat when the click goes silent, and get a timing score out of 100 to share.
