Dotted eighth magic
At 120 BPM, a dotted eighth lands at 375 ms—the classic U2 delay feel that slots between vocal phrases.

How to use this BPM to delay calculator
Type your session tempo and grab the millisecond or Hertz readout for any subdivision. Use the dotted and triplet rows to add swing to straight performances, or grab the bar length in seconds for ambient pads, tremolo, or autopan. Everything runs locally in your browser—no uploads, accounts, or tracking.
For vocals, try a short pre-delay (10–40 ms) on room or plate reverbs to keep consonants crisp. Guitarists chasing a dotted-eighth feel can change songs quickly by updating BPM and copying the new millisecond value. If you’re working in film or games, bar lengths in seconds help align tempo-locked cues to frame-accurate edits.
Save your favorite times in your session notes, and pair this with the bar/beat Hertz readouts when hardware pedals or synths only expose frequency instead of musical divisions.
5 Fun Facts for Mixers
Tempo vs. division
Halving BPM gives the same times as doubling your note length; you can double either tempo or subdivision to stay on-grid.
Same groove
Modulation sweet spots
Chorus, tremolo, and autopan often sound more musical at bar or half-note rates than at eighths.
LFO pacing
Pre-delay clarity
Short reverbs with 10–40 ms of pre-delay keep vocals intelligible while leaving space around consonants.
Vocal space
Triplets add swing
Triplet delays create groove without changing the performance—instant shuffle without MIDI quantize.
