How it works
Formula
Quarter note = 60000 ÷ BPM msOther notes = quarter × 4 ÷ denominator; dotted × 1.5; triplet × 2/3Rate (Hz) = 1000 ÷ length (ms)Worked example
Given: 120 BPM
- Quarter = 500 ms; eighth = 250 ms.
- Dotted eighth = 375 ms; eighth triplet ≈ 166.67 ms.
Result: The classic dotted-eighth delay is 375 ms.

FAQ
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, dotted ×1.5, triplet ×2/3.
Which delay time is most common?
A dotted eighth (375 ms at 120 BPM) gives the classic rhythmic echo; vocals often use quarter or eighth notes.
Why does pitch change with tempo?
Speeding up without time-stretching raises pitch too: a speed ratio r shifts pitch by 12 × log₂(r) semitones.
