BPM: Slow dub/reggae

Give tempo and time signature

BPM parameters

  • Beats-per-minute: 75 BPM
  • Beats-per-second: 1.25 Hz
  • Length of 1 beat: 0.8 second = 800 msec
  • Length of 1 bar (4 beats): 3.2 second

    • Loop & song length

    These are the lengths of multiple beats (handy for calculating loop lengths, LFO)
    1 beat =800ms =1.25Hz
    2 beats =1.6sec =0.63Hz
    3 beats =2.4sec =0.42Hz
    4 beats =3.2sec =0.31Hz
    6 beats =4.8sec =0.21Hz
    7 beats =5.6sec =0.18Hz
    8 beats =6.4sec =0.16Hz
    10 beats =8sec =0.13Hz
    12 beats =9.6sec =0.1Hz
    16 beats =12.8sec =0.08Hz
    24 beats =19.2sec =0.05Hz
    32 beats =25.6sec =0.04Hz
    These are the lengths of multiple bars/measures (handy for estimating the length of a song).
    2 bars =6.4 sec
    4 bars =12.8 sec
    8 bars =25.6 sec
    16 bars =51.2 sec
    24 bars =76.8 sec
    32 bars =102.4 sec
    40 bars =128 sec
    48 bars =153.6 sec
    60 bars =192 sec
    80 bars =256 sec
    100 bars =320 sec
    120 bars =384 sec
