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 = 6 / 8 of a beat
  • = 375 msecs
  • Repeated delays

  • delay syncs with the beat after 4 repetitions = 3 beats
  • x 2 = 750 msecs
  • x 3 = 1125 msecs
  • x 4 = 1500 msecs
  • Delay vs beat
