Loop Length Calculator
Calculate the exact length of a musical loop in seconds and samples based on BPM and number of bars.
Loop Duration
Loop length is determined by tempo (BPM) and the number of bars.
Seconds per Beat = 60 / BPM
Beats per Bar = Time Signature (usually 4)
Loop Length = Seconds per Beat × Beats per Bar × Number of Bars
Sample count:
Samples = Loop Length in Seconds × Sample Rate
Common sample rates:
| Quality | Sample Rate |
|---|---|
| CD Quality | 44,100 Hz |
| DVD Quality | 48,000 Hz |
| Hi-Res | 96,000 Hz |
Example: 4 bars at 120 BPM in 4/4 time: (60/120) × 4 × 4 = 8 seconds = 352,800 samples (at 44.1 kHz)
