Calculate audio delay times in milliseconds based on BPM. Get sync-friendly echo, reverb, and delay tap values for music production.
The Audio Delay Calculator helps musicians, producers, and sound engineers determine precise delay times synchronized to a song's tempo. When producing music, delay effects that are mathematically aligned to the beat per minute (BPM) create a rhythmic, musical echo rather than a disjointed, off-beat repetition.
This tool computes straight, dotted, and triplet delay times for common note divisions — from whole notes down to 1/64th notes. Whether you're setting up a slapback echo on a vocal track, dialing in a dotted-eighth guitar delay, or configuring reverb pre-delay, having the exact millisecond value ensures your effects sit perfectly in the mix.
Professional producers rely on tempo-synced delays to add depth and space without muddying the arrangement. Instead of guessing or manually calculating 60000 / BPM, this calculator instantly provides every useful note value so you can focus on the mix. It also keeps dotted and triplet values visible so you can compare the feel before you drop them into the DAW.
Use this calculator when you need delay times that stay locked to tempo instead of guessing millisecond values by hand. It is useful for guitar delays, slapback echoes, reverb pre-delay, and any mix where rhythmic timing matters. It also speeds up setting a mix to the song BPM instead of nudging delay times manually.
Delay (ms) = (60,000 / BPM) × multiplier. Straight: 4/n, Dotted: 6/n, Triplet: 8/(3n). For example, quarter note = 60000/BPM, dotted quarter = 60000/BPM × 1.5, triplet quarter = 60000/BPM × 2/3.
Result: 500 ms (quarter note)
At 120 BPM, a quarter note delay is 60000 / 120 = 500 ms. A dotted quarter is 750 ms, and a triplet quarter is 333.33 ms.
Delay is one of the most fundamental effects in music production. At its core, delay simply repeats the input signal after a set time interval. When that interval aligns with the tempo of the music, the echoes reinforce the rhythm and add depth without cluttering the mix.
The basic formula is straightforward: a quarter note at any BPM equals 60,000 milliseconds divided by the BPM. From there, all other note values are simple fractions or multiples. Half notes are double the quarter note time, eighth notes are half, and so on.
Straight note values divide time evenly by powers of two. A quarter note is one beat, an eighth note is half a beat, a sixteenth is a quarter beat. Dotted notes add 50% — a dotted quarter lasts 1.5 beats, creating an offset that sounds syncopated. Triplet notes divide the beat into three, giving a shuffled, swinging feel.
Each type serves different creative purposes. Straight delays reinforce the grid, dotted delays create forward momentum, and triplet delays introduce groove and swing. Knowing which to use — and having the exact ms value — is essential for professional-sounding mixes.
Beyond simple echo effects, tempo-synced delay times are used for reverb pre-delay, chorus rate settings, tremolo speed, auto-pan timing, and even sidechain compression release times. Understanding the relationship between BPM and milliseconds unlocks precise control over nearly every time-based effect in your DAW.
Tempo-synced delay is a delay effect where the echo time is mathematically aligned to the BPM of the song, so the echoes fall on beat divisions and sound rhythmic rather than random. That keeps the repeats locked to the groove instead of drifting against it.
A dotted note adds 50% to the straight note value. Dotted eighth notes are extremely popular in guitar effects, famously used by U2's The Edge. They create a syncopated feel that sits between the main beats.
A triplet delay divides the beat into three equal parts instead of two, giving a swing or shuffle feel to the echoes. It is a common choice when you want the repeats to feel looser than straight notes.
Pre-delay sets a gap before reverb starts. Values of 10-80 ms help keep the dry signal clear. Use shorter pre-delays for ambient sounds and longer ones for lead vocals or instruments.
Slapback echo typically uses very short delays of 60-120 ms regardless of BPM. It's a single repeat style common in rockabilly and country music.
Absolutely. Non-synced delays can create interesting textures and ambience. However, synced delays are preferred when you want rhythmic echoes that groove with the music.
