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: 135 BPM
  • Beats-per-second: 2.25 Hz
  • Length of 1 beat: 0.4444 second = 444.4 msec
  • Length of 1 bar (4 beats): 1.7778 second
  • Fraction → msecs

  • Delay = 4 / 1 of a beat
  • = 1777.6 msecs
  • How to use this page
