BPM parameters

  • Beats-per-minute: 135 BPM
  • Beats-per-second: 2.25 Hz
  • Length of 1 beat: 0.4444 second = 444 msec
  • Length of 1 bar (4 beats): 1.7778 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =444ms =2.27Hz
    2 beats =889ms =1.12Hz
    3 beats =1.33sec =0.75Hz
    4 beats =1.78sec =0.56Hz
    6 beats =2.67sec =0.37Hz
    7 beats =3.11sec =0.32Hz
    8 beats =3.56sec =0.28Hz
    10 beats =4.44sec =0.23Hz
    12 beats =5.33sec =0.19Hz
    16 beats =7.11sec =0.14Hz
    24 beats =10.67sec =0.09Hz
    32 beats =14.22sec =0.07Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =3.6 sec
    4 bars =7.1 sec
    8 bars =14.2 sec
    16 bars =28.4 sec
    24 bars =42.7 sec
    32 bars =56.9 sec
    40 bars =71.1 sec
    48 bars =85.3 sec
    60 bars =106.7 sec
    80 bars =142.2 sec
    100 bars =177.8 sec
    120 bars =213.3 sec
