A BPM to delay time calculator converts beats per minute into millisecond values for delay, reverb, and LFO effects. Musicians, producers, and sound designers use these timing values to sync effects precisely to a song's tempo — keeping every echo, modulation, and reverb tail locked to the beat.

How to Use the BPM to Delay Time Calculator
Setting delay and reverb times by ear is frustrating and imprecise. When your effects are not synced to the tempo, echoes land off-beat, reverb tails clash with the next note, and LFO modulation drifts out of phase. This free BPM to delay calculator eliminates the guesswork by converting any tempo into exact millisecond values for every standard note division.
Step 1: Enter Your BPM
Type your song's tempo into the BPM input field, or use the preset buttons for common tempos like 120, 128, or 140 BPM. You can also use the +/- buttons to nudge the tempo up or down by one BPM. The delay table updates instantly as you change the value, so you can experiment freely.
Step 2: Read the Timing Table
The table shows delay times for seven note values: whole note (4 beats), half note (2 beats), quarter note (1 beat), eighth note (1/2 beat), sixteenth note (1/4 beat), and thirty-second note (1/8 beat). Each note value is shown in three variations: straight, dotted (x1.5), and triplet (x2/3). Click any value to copy it to your clipboard.
Step 3: Copy Values to Your DAW or Pedal
Click any millisecond value in the table to copy it to your clipboard. Then paste it directly into your delay plugin, reverb decay parameter, or LFO rate field. If your hardware or software uses Hz instead of milliseconds, toggle the Hz display to see frequency values alongside the timing data.
Understanding Dotted and Triplet Delays
Dotted delays are 1.5 times the straight value and create a swinging, ping-pong style echo — think The Edge from U2 or ambient post-rock textures. Triplet delays are 2/3 of the straight value and produce a driving, bouncing rhythm often heard in dub reggae, hip-hop, and electronic music. Combining both dotted and triplet delays across stereo channels creates rich, complex echo patterns.
Common Use Cases
Beyond standard delay effects, these timing values are used for setting reverb pre-delay, configuring sidechain compression release times, dialing in tremolo and vibrato rates, programming LFO speeds on synthesizers, and calculating audio buffer sizes. Any time an effect parameter needs to be synchronized with the song's tempo, this calculator gives you the exact value.
Frequently Asked Questions
Is this BPM to delay calculator free?
Yes, this tool is completely free with no usage limits. You can convert any BPM to delay times as many times as you need. There is no signup, no account, and no premium features locked behind a paywall.
Is my data private when using this tool?
Absolutely. Everything runs entirely in your browser using JavaScript. No data is ever sent to a server. The tool works completely offline once the page loads, so your BPM values and timing data stay on your device.
How do I calculate delay time from BPM?
The formula is simple: divide 60,000 by the BPM to get the quarter note delay in milliseconds. For example, at 120 BPM, one quarter note is 60,000 / 120 = 500 ms. Multiply by 2 for half notes, by 4 for whole notes, or divide by 2 for eighth notes.
What is a dotted delay time?
A dotted note is 1.5 times the length of the base note. For example, a dotted quarter note at 120 BPM is 500 ms x 1.5 = 750 ms. Dotted delays create a swinging, rhythmic echo effect that feels musical and is popular in ambient and post-rock guitar tones.
What is a triplet delay time?
A triplet divides a beat into three equal parts instead of two, making each note two-thirds the length of the straight version. At 120 BPM, a quarter note triplet is 500 ms x 2/3 = 333 ms. Triplet delays add a driving, bouncing feel popular in funk, hip-hop, and electronic music.
What is the Hz column used for?
The Hz (Hertz) column shows the frequency equivalent of each delay time, calculated as 1000 divided by the milliseconds. This is useful for setting LFO rates, filter modulation speeds, and tremolo frequencies in synthesizers and effects processors that use Hz instead of milliseconds.
How do I use these delay values in my DAW?
Most DAWs and delay plugins let you type in a delay time in milliseconds. Simply enter the BPM of your project, find the note value you want from the table, and type that millisecond value into your delay plugin's time parameter. Turn off tempo sync on the plugin first so it accepts manual ms values.
What BPM range does this tool support?
This tool supports any BPM from 1 to 999. Most music falls between 60 and 200 BPM, but the calculator works for any tempo. Extremely slow tempos will produce very long delay times in seconds, while fast tempos produce very short delay times suitable for chorus and flanger effects.
