    How to use this page

  • If you have a 135 BPM song and you want a phase modulation of 4 beats: that is 1.78 sec (BEATS)
  • If you have a 98 BPM song in a measure of 3/4, and you want to know how long 32 bars is: 58.78 sec (BARS)
  • If you have a 128 BPM song and you want an audio delay of 2/3 of a beat: this is 313 ms (FRACTIONS)
  • Fractions

    These are some common fractions (handy for setting delays and modulation parameters)
