BPM Tapper & Delay Calculator
Tap along to a track to find its tempo, check it against a metronome, then copy delay and reverb times that sit on the grid. Free, no account needed.
How to use it
- Tap the pad or press T along with the beat: four or more taps give a steady reading.
- Fine-tune the tempo with − and +, type it in, or halve or double it if you counted in half time.
- Start the metronome to check the tempo against the track. Tapping while it plays moves its downbeat onto your taps.
- Click any value in the tables to copy it, then paste it into your delay, reverb, LFO or compressor release.
Questions
It averages the intervals between your last eight taps, so the reading settles within two bars. Pause for two seconds and the next tap starts a fresh count. The result is rounded to a whole BPM, the way most DAWs set the project tempo.
A dotted note lasts one and a half times its straight value: a dotted 1/8 at 120 BPM is 375 ms. A triplet fits three notes into the space of two, so it lasts two thirds: a 1/8 triplet at 120 BPM is 166.7 ms. Dotted 1/8 is the classic rhythmic echo; triplets swing.
Switch to Hz for anything that cycles: LFO rate, tremolo, auto-pan or chorus speed on plugins without tempo sync. One cycle per 1/4 note at 120 BPM is 2 Hz.
Each space gives the tail a note length to fill, from a 1/4 note for a tight room to two bars for a hall, plus a short pre-delay on the grid. Decay is that length minus the pre-delay, so the tail fades just before the next hit instead of washing over it.
