# Audio delay calculator

### Give the tempo and the time signature

Express the length of the delay as fractions of a bar

If you have a 135 BPM song, and you want a phase modulation of 4 beats (1 bar): that is 1777.6 ms
If you have a 128 BPM song, and you want an audio delay of 2/3 of a beat: this is 312.5 ms
