How the Calculation Works

The length of a song is calculated based on the tempo (BPM), time signature (beats per bar), and the total number of bars:

Length of 1 Beat = 60 / BPM seconds
Length of 1 Bar = (Beats per Bar) × (Length of 1 Beat)
Total Duration = (Number of Bars) × (Length of 1 Bar)

For example, at 108 BPM with 4 beats per bar:

  • Each beat is 0.5556 seconds (60 ÷ 108)
  • Each bar is 2.2222 seconds (4 × 0.5556)
  • An 80-bar song would be 177.776 seconds (80 × 2.2222) or 2 minutes 57.776 seconds
