Audio delay calculator

Give the tempo and the time signature

Express the length of the delay as fractions of the beat

Beats/minute → msecs/beat

  • Beats-per-minute: 120 BPM
  • Beats-per-second: 2 Hz
  • Length of 1 beat: 0.5 second = 500 msec
  • Length of 1 bar (4 beats): 2 second
  • Fraction → msecs

  • Delay = 1 / 12 of a beat
  • = Triplet note
  • = 41.7 msecs
  • Repeated delays

  • delay syncs with the beat after 12 repetitions = 1 beats
  • x 2 = 83 msecs
  • x 3 = 125 msecs
  • x 4 = 167 msecs
  • x 5 = 208 msecs
  • x 6 = 250 msecs
  • x 7 = 292 msecs
  • x 8 = 333 msecs
  • x 9 = 375 msecs
  • x 10 = 417 msecs
  • x 11 = 458 msecs
  • x 12 = 500 msecs

    How to use this page

  • If you have a 135 BPM song and you want a phase modulation of 4 beats: that is 1777.6 sec
  • If you have a 128 BPM song and you want an audio delay of 2/3 of a beat: this is 312.5 ms
