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: 140 BPM
  • Beats-per-second: 2.3333 Hz
  • Length of 1 beat: 0.4286 second = 428.6 msec
  • Length of 1 bar (4 beats): 1.7143 second
  • Fraction → msecs

  • Delay = 5 / 16 of a beat
  • = 133.9 msecs
  • Repeated delays

  • delay syncs with the beat after 16 repetitions = 5 beats
  • x 2 = 268 msecs
  • x 3 = 402 msecs
  • x 4 = 536 msecs
  • x 5 = 670 msecs
  • x 6 = 804 msecs
  • x 7 = 938 msecs
  • x 8 = 1072 msecs
  • x 9 = 1205 msecs
  • x 10 = 1339 msecs
  • x 11 = 1473 msecs
  • x 12 = 1607 msecs
  • x 13 = 1741 msecs
  • x 14 = 1875 msecs
  • x 15 = 2009 msecs
  • x 16 = 2143 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
