Delay Time Calculator

Enter your tempo to get delay times in milliseconds for every note value. Use the straight column for classic echoes, dotted for that off-beat bounce, and triplet for swung repeats.

Rate is the straight note value as a frequency, handy for dialling in LFOs and tremolo by hand.

Reverb starting points

  • Tight pre-delay (1/64): 27.2 ms
  • Open pre-delay (1/32): 54.3 ms
  • Short decay (half bar): 869.6 ms
  • Medium decay (one bar): 1739.1 ms
  • Long decay (two bars): 3478.3 ms

Decay times assume 4/4. Dial the tail back until it clears the next downbeat if the mix starts to smear.
