BPM to MS: Delay Time Calculator

Yes. It is free, needs no account and works on any device.

Divide 60,000 by the BPM to get one beat in milliseconds. At 90 BPM that is 666.67 ms; an eighth note is half of that.

Three-quarters of a beat: 1.5 times an eighth note. It is the classic rhythmic delay in rock and worship guitar. At 120 BPM it is 375 ms.

Most DAW plugins can sync to the tempo directly. The calculator is for gear and settings that only take milliseconds, and for checking a synced value.

A delay set to a note value repeats in time with the song, so the echoes sit inside the groove instead of fighting it. Plugins with a sync button do this for you; hardware pedals, many reverbs' pre-delay and compressor release times need the number in milliseconds.

One beat lasts 60,000 divided by the BPM, in milliseconds: 500 ms at 120 BPM. Halve it for an eighth note, double it for a half note. A dotted note is 1.5 times as long, and a triplet is two-thirds as long.

The Rate column turns each note value into a frequency in Hz, one cycle per note. Set a tremolo, auto-pan or filter LFO to it and the movement locks to the tempo.

No. The free tools need no account and no download. They run in your browser, and nothing you play or drop in is uploaded.
