Reverb and delay calculator

How to Use This Tool Efficiently

1. Start with the BPM – Enter the tempo of your track. This is the foundation for all calculations.
2. Select the Time Signature – While most popular music is in 4/4, choosing the correct time signature ensures reverb decay times match the measure length.
3. Apply the Values – Use the calculated numbers to set delay times on your plugins or hardware, and adjust reverb pre-delay and decay to maintain clarity in the mix.
4. Fine-Tune by Ear – While these values provide a solid starting point, always tweak settings based on the feel of the track. Music is as much about emotion as it is about numbers.

You can use this calculator to ensure that delays and reverbs don’t clash with the groove of a song. When effects are out of sync, they can create an unintended wash of sound that muddies the mix. But when dialed in properly, delays reinforce the groove, and reverb tails decay in time with the beat, adding depth without overpowering the arrangement.
