BPM to Milliseconds & Delay Time Calculator
Delay and LFO times for every note value, tap tempo, bars ↔ seconds and tempo-change math
How it works
A quarter note lasts 60000 / BPM milliseconds; every other value scales from that (dotted × 1.5, triplet × 2/3). The table gives each note value in ms, as an LFO rate in Hz and in samples at your sample rate — the numbers you type into delays, compressors' release times and LFOs. Tap tempo averages your last taps. The converters go the other way (a 375 ms delay is an eighth note at 80 BPM), turn bars into seconds for loop lengths, and show what a tempo change does to speed and pitch if the audio is repitched rather than time-stretched.
Questions
How do I convert BPM to milliseconds?
One beat (quarter note) = 60000 ÷ BPM ms. At 120 BPM that's 500 ms; an eighth is 250 ms, a dotted eighth 375 ms, an eighth-note triplet 166.7 ms.
What is a dotted or triplet delay?
Dotted values are 1.5× the straight value; triplets are 2/3 of it. Dotted-eighth delays give the classic U2 rhythm; triplet delays swing.
How do I turn a delay time into a tempo?
BPM = 60000 × beats ÷ ms. Enter the milliseconds and the note value it represents.
