BPM Delay Time Calculator

How to use

1. 1Type a tempo in the BPM field, or pick a quick preset (60, 80, 90, 100, 120, 128, 140, 150, or 174 BPM). The +/-1 buttons and the slider let you nudge or scrub the tempo.
2. 2Pick a time signature (4/4 by default) to set the length of one bar. Note values are measured against the quarter-note beat and stay the same across common time signatures.
3. 3Read the four headline figures: tempo, the duration of one quarter-note beat, the beat frequency in Hz, and the length of one bar.
4. 4Use the delay-time table for the exact millisecond and hertz value of every note length, with straight, dotted, and triplet variants side by side.
5. 5Tap the Copy button next to any cell to grab that single millisecond value, ready to paste into a delay, reverb, or LFO field.
6. 6Scroll to the effect cards for ready-made picks for delay and echo, reverb pre-delay, LFO and chorus rate, and sidechain compression release.
7. 7Click Copy summary to grab a CSV of every note value at the current tempo, plus the tempo, quarter-note duration, and bar length, in one block.

About this tool

BPM Delay Time Calculator turns a tempo in beats per minute into the exact delay and effect times every music producer reaches for. Type any tempo from 20 to 999 BPM (or pick a quick preset like 90, 120, 128, 140, or 174) and the tool returns the duration of one beat, the beat frequency in Hz, and the duration of a full bar in the time signature of your choice (4/4, 3/4, 2/4, 6/8, 9/8, 12/8, 5/4, and 7/8). The headline table covers every common note length from whole through sixty-fourth and shows each value in three variants: straight, dotted (the value times 1.5), and triplet (the value times two thirds). Every cell shows both the time in milliseconds and the matching frequency in hertz, and a copy button next to each value grabs the millisecond figure to three decimal places ready to paste into a delay plugin, a reverb pre-delay field, or an LFO rate input. The math is the standard formula every DAW uses internally: quarter_ms equals 60000 divided by BPM; any other note value is the quarter scaled by its length in beats; dotted notes multiply by 1.5; triplet notes multiply by 2/3; and the frequency in Hz is 1000 divided by the note duration in ms. Below the table, four effect-specific cards translate the raw numbers into practical settings: delay and echo recommendations cover slap-back vocals, the classic dotted-eighth guitar delay popularised by U2 and The Edge, quarter-note throws for pads and ad-libs, and triplet eighths that shuffle a 4/4 part; reverb pre-delay picks short, medium, and long values that keep the tail clean behind percussive, lead vocal, and ambient material; LFO and chorus rate picks slow auto-pan, medium tremolo, and fast chorus rates that lock to the groove; sidechain compression release picks short eighth-note pumping pads and tight sixteenth-note bass ducks. Useful in every modern DAW (Ableton Live, Logic Pro, FL Studio, Pro Tools, Reaper, Bitwig Studio, Studio One, Cubase, Reason, GarageBand) and every delay or reverb plugin that takes a value in milliseconds instead of a note division. Built for producers writing house, techno, hip hop, pop, trap, drum and bass, ambient, indie, rock, country, and lo-fi, for guitarists dialling pedal delay times, for mixing engineers setting parallel delay on lead vocals, for podcast and video editors syncing music beds, and for music theory students learning how note values translate to time at any tempo.
