BPM Delay Calculator

Convert a tempo into a rhythmically synchronized delay time in milliseconds for plugins, pedals, vocal effects, reverb pre-delay, synths, and hardware processors.

This BPM delay calculator online is a BPM delay calculator free to use, with no account, upload, or installation required.

How to Use the BPM Delay Calculator

  1. Enter the tempoUse a project tempo from 20 to 400 BPM.
  2. Add decimal precisionEnter a decimal BPM when more exact timing is required.
  3. Select a note valueChoose one of the available rhythmic subdivisions.
  4. Calculate the delayClick Calculate delay time.
  5. Apply the resultEnter the displayed millisecond value into your effect or processor.

The calculator displays the duration of the selected note value. It does not automatically change settings in your DAW, plugin, or pedal.

BPM-to-Delay Formula

Quarter-note time60,000 ÷ BPM
Delay time in milliseconds60,000 ÷ BPM × note multiplier

60,000 is the number of milliseconds in one minute, BPM is the tempo in beats per minute, and the note multiplier represents the selected rhythmic division.

Supported note valueMultiplierFormula
Whole note4Quarter-note time × 4
Dotted half3Quarter-note time × 3
Half note2Quarter-note time × 2
Dotted quarter1.5Quarter-note time × 1.5
Quarter note160,000 ÷ BPM
Dotted eighth0.75Quarter-note time × 0.75
Quarter-note triplet2 ÷ 3Quarter-note time × 0.6667
Eighth note0.5Quarter-note time ÷ 2
Eighth-note triplet1 ÷ 3Quarter-note time × 0.3333
Sixteenth note0.25Quarter-note time ÷ 4

A dotted note lasts 1.5 times as long as its corresponding straight note. Triplet values divide a larger rhythmic span into three equal parts.

Example: Delay Times at 120 BPM

At 120 BPM, the quarter-note duration is:

Quarter-note calculation60,000 ÷ 120 = 500 ms
Note valueDelay time
Whole note2,000 ms
Dotted half1,500 ms
Half note1,000 ms
Dotted quarter750 ms
Quarter note500 ms
Dotted eighth375 ms
Quarter-note triplet333.33 ms
Eighth note250 ms
Eighth-note triplet166.67 ms
Sixteenth note125 ms
06 · Choose the rhythm

Choosing a Delay Subdivision

Whole or half noteLong, widely spaced repeats
Quarter noteEchoes aligned with the main beat
Dotted quarterLonger syncopated repeats
Eighth noteFaster, more compact echoes
Dotted eighthRhythmic and syncopated delay patterns
Quarter-note tripletRolling echoes across the beat
Eighth-note tripletFaster shuffled or triplet repeats
Sixteenth noteTight delays for vocals, guitars, and synths

The calculated value is especially useful when a delay effect accepts milliseconds but does not include automatic BPM synchronization.

07 · Space and depth

Reverb and Pre-Delay Timing

The same note-duration calculation can provide a starting point for reverb pre-delay. For example, the supported sixteenth-note value at 120 BPM is 125 ms.

A dedicated reverb calculator may also calculate decay or reverb-tail length. This tool does not calculate room size, decay time, feedback, or wet/dry balance. It only converts BPM and the selected note value into milliseconds.

As a basic delay & reverb calculator, it provides a musical timing reference that can be adjusted for the vocal, instrument, arrangement, and desired sense of space.

Vocal Delay Calculator

The calculator can also find tempo-synchronized vocal delay settings.

Vocal timing example

Sixteenth-Note Delay at 100 BPM

Delay calculation60,000 ÷ 100 × 0.25 = 150 ms

Use the calculated value as a starting point. Shorten the delay if words or consonants become blurred, or lengthen it when the repeat should sound deliberately late.
