How to use this calculator

Use tempo divisions as a starting point for reverb pre-delay decisions.

How the calculation works

  • Enter BPM.
  • Review short rhythmic timing values.
  • Pick a value that leaves room for the dry sound.

Formula

Reference pre-delay values reuse BPM note timing divisions.

Example

At 120 BPM, 1/64 is about 31 ms and 1/32 is about 63 ms.

Understanding your result

Use the output as a practical starting point, then review it before using it in an important workflow.

Assumptions and limitations

  • There is no universally correct reverb pre-delay.
  • Use these values as references, then adjust by ear.
