Free BPM to Delay Time Calculator

How to Use This Delay Time Calculator

Set your track's BPM using the slider, the number box, or by tapping the "Tap Tempo" button in rhythm with your song. The table below updates live, showing the exact delay time in milliseconds for every common note value — straight, dotted, and triplet — so you can dial your delay or reverb pre-delay in to match your track's tempo perfectly.

Unique Feature: Voice Feedback

Turn on Voice Feedback and tap any value in the table — the calculator speaks the millisecond number aloud. This is useful when you're reaching for a hardware delay pedal or outboard unit and don't want to look away from the dial to read the screen.

Why Sync Delay & Reverb to BPM

Delay and reverb effects that are set independently of a track's tempo can clash rhythmically with the beat, muddying the mix. Setting your delay time to a note value that matches the BPM makes echoes land in rhythm with the song, while a tempo-matched reverb pre-delay keeps the reflections from smearing into the next transient. Most modern delay plugins can sync automatically, but many hardware units and older plugins need the exact millisecond value entered manually — that's exactly what this calculator gives you.

The Formula Behind the Numbers

The calculation is straightforward: a quarter note's duration in milliseconds equals 60,000 divided by the BPM. Every other note value is a simple multiple or fraction of that: eighth notes are half a quarter note, triplets are two-thirds of their parent note value, and dotted notes are one-and-a-half times their base value. This calculator runs that math instantly so you never have to do it by hand mid-session.
