Reference & details

How it works

Quarter Note Delay

60 seconds × 1000 ms divided by beats per minute gives one quarter note duration in milliseconds.

Delay (ms) = 60,000 ÷ BPM

Subdivision Delay

Divide or multiply quarter note delay by subdivision ratio for syncopated delay patterns.

Eighth = Quarter ÷ 2 | Dotted eighth = Quarter × 0.75 | Triplet eighth = Quarter ÷ 3

Slapback Delay

Classic rockabilly slapback uses 60–120 ms regardless of tempo — not tempo-synced but historically important delay range.

Slapback = 60–120 ms (tempo-independent)

Updated: July 2026

Example Scenarios

Quarter = 500 ms. Dotted eighth = 375 ms — classic U2/The Edge style arpeggiated delay pattern.

667 ms delay for spacious, obvious rhythmic echo on vocal or guitar in slow ballad.

Quarter = 429 ms. Triplet eighth = 143 ms — fast shimmer delay for dense mix textures.

FAQ

Delay (ms) = 45,000 ÷ BPM. At 120 BPM: 375 ms. Creates the classic 'one repeat between notes' rhythmic delay pattern popular in rock and ambient music.

Short single repeat at 60–120 ms, popularized in 1950s rock and roll. Not tempo-synced — fixed time regardless of BPM. One distinct echo, not rhythmic pattern.

Tempo-synced delay sits musically in the mix. Free-time delay can clash with groove. Use BPM calculation for rhythmic effects; manual time for ambient/special effects.

Feedback controls repeat decay. Longer delay times with high feedback create dense textures. Lower feedback (1–3 repeats) keeps rhythmic clarity.

Manual adjustment or tap tempo required during tempo ramps. Some digital delays and DAW plugins track host tempo automatically.

About Delay Time Calculator

Tempo-synced delay effects require precise millisecond timing derived from BPM. Enter song tempo and note value to calculate delay time for quarter notes, eighth notes, dotted eighths, triplets, and other rhythmic subdivisions.
