A single-page tool that converts a song's tempo (BPM) into delay times and modulation rates for common note divisions — for audio engineers and music producers dialing in delay/echo effects.
Enter a BPM (20–300, via slider or number field) and the page instantly computes, for each note division from whole note down to thirty-second note:
- Delay time in milliseconds — what to punch into a delay plugin
- Rate in Hz — for LFOs/modulation synced to the same note value
- Toggle between Normal, Dotted (×1.5), and Triplet (×2/3) note values
- A pulsing indicator that blinks at the current quarter-note tempo as a visual reference
The formula (60,000 ÷ BPM = ms per quarter note) is shown at the bottom of the page for reference.
