How to use
- Type a tempo, or tap the button in time with the music to find it.
- Choose your frame rate to see frames per beat.
- Read the delay table for every note value, in straight, dotted and triplet timing.
- Use the millisecond figures for echo and delay effects, or the frame figures to cut on the beat.
Examples
- At 120 BPM a quarter note is 500 ms, so a quarter-note delay set to 500 ms locks an echo to the track.
- A dotted eighth delay at 120 BPM is 375 ms, the classic rhythmic delay used on guitars and synth lines.
- At 24 fps and 128 BPM a beat is just under 12 frames, so cutting every twelve frames keeps an edit riding the tempo.
Frequently asked questions
How does tap tempo work?
It measures the time between your taps and averages the most recent ones into a tempo. Tap steadily for four or more beats for a stable reading, and pausing resets it for a fresh attempt.
What are dotted and triplet timings?
A dotted note lasts one and a half times its straight value, giving a rolling feel. A triplet fits three notes in the space of two, a tighter syncopated feel. Both are common delay settings for rhythmic interest.
How do I sync edits to music?
Convert the tempo to frames per beat at your frame rate, then place cuts on those frame intervals. Editing on the beat makes a sequence feel intentional and tight rather than loose against the track.
