Perry’s Reverb Rhythm Calculator

Screenshot 1Perry’s Reverb Rhythm Calculator is a utility for musicians (as well as mixing and mastering engineers) that will compute reverb pre-delay and decay values (in milliseconds) for you to use with your reverb plugins. These values are specifically synchronized to the rhythm of a chosen Tempo (BPM), and an offset slider allows for slight adjustments to the output.

This simple tool will calculate reverb timings, allowing the music producer to trigger their reverb to start and stop on a rhythm/tempo, instead of randomly. While many producers may overlook this aspect of sound optimization, aligning a song’s reverb to a rhythm/tempo can help tighten, louden and enrich the overall sound.

Reverb is often used to add depth and space to a song, but when overused or used incorrectly, it’s an effect that can do more harm than good to a mix. When the tail end of a reverb tapers off, that sudden “loss” of reverb sound can create it’s own rhythm/tempo in a song, which may detract from and muddy up the main song  rhythm/tempo.

Computations are based on a method originally posted by Storyville titled Reverb: Tips and Techniques. Matthew Weiss wrote a decent article titled The Importance of Space in a Mix: Part 2, which also hints on the importance of rhythm for reverb. These ideas are not far off from the Wall of Sound technique developed by Phil Spector at Gold Star Studios. Some more info about reverb in a mix can be found here and here.


  • Convert from BPM to milliseconds.
  • Compute reverb pre-delay and time values in milliseconds.
  • Millisecond offset allows for fine tuning to taste.

All of my software comes with the same disclaimer. I do test and use my own software programs, and while I’m pretty confident there are no dire consequences to using them, I can’t be held liable for any damage caused by the use of my software, whether due to bugs, unforseen functionality or any other reason. I always recommend that you test my software on a sample before attempting the real thing. This will give you an idea of how it works and what to expect. Thank you for your interest in my software!
