Reverb and Delay Time Calculator


To calculate a tempo matched reverb time:

1. Enter your BPM above
2. Choose the length and a pre-delay time.
3. Minus the pre-delay time from length to find the decay time.

Example: 120 bpm, 1 bar = 2000 ms, 1/64 pre-delay = 31.25 ms

Reverb Settings: Pre-delay = 31.25 ms, decay time = 1968.75 ms (2000-31.25)

Experiment with different pre-delay settings and decay times to create different reverb effects.

Using very large decay times and short pre-delays can create cathedral like spaces:
Example: 120 bpm, 1 bar = 2000 ms, 4 bars = 8000 ms, 1/256 pre-delay time = 7.81 ms
Reverb Settings: Pre-delay = 7.81 ms, decay time = 7992.19 ms (8000-7.81)

Using longer pre-delay times with short decay times can create interesting slapbacks.
Example: 120 bpm, 1/4 note = 500 ms, 1/8 pre-delay time = 250 ms
Reverb Settings: Pre-delay = 250 ms, decay time = 250 ms (500-250)

Try adjusting the pre-delay and decay times slightly away from being exactly synced to the tempo to adjust the groove of the track.
