BPM parameters

  • Beats-per-minute: 98 BPM
  • Beats-per-second: 1.6333 Hz
  • Length of 1 beat: 0.6122 second = 612 msec
  • Length of 1 bar (3 beats): 1.8367 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =612ms =1.64Hz
    2 beats =1.22sec =0.82Hz
    3 beats =1.84sec =0.54Hz
    4 beats =2.45sec =0.41Hz
    6 beats =3.67sec =0.27Hz
    7 beats =4.29sec =0.23Hz
    8 beats =4.9sec =0.2Hz
    10 beats =6.12sec =0.16Hz
    12 beats =7.35sec =0.14Hz
    16 beats =9.8sec =0.1Hz
    24 beats =14.69sec =0.07Hz
    32 beats =19.59sec =0.05Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =3.7 sec
    4 bars =7.3 sec
    8 bars =14.7 sec
    16 bars =29.4 sec
    24 bars =44.1 sec
    32 bars =58.8 sec
    40 bars =73.5 sec
    48 bars =88.2 sec
    60 bars =110.2 sec
    80 bars =146.9 sec
    100 bars =183.7 sec
    120 bars =220.4 sec
