Tap tempo BPM calculator and beats-per-minute to milliseconds converter. Sync delay, loops, and metronome timing for music production workflows.
Convert between audio sample rates including 44.1 kHz, 48 kHz, 96 kHz, and 192 kHz. Check file duration and sample count when changing rates.
Calculate decibel levels, dB addition, voltage-to-dB conversion, and SPL at distance. Compare sound pressure ratios for audio and acoustics work.
Base delay time aligns one repeat per beat at the project tempo.
Quarter delay (ms) = 60,000 / BPMDivide or multiply quarter-note ms for note values. Dotted notes multiply by 1.5; triplets multiply by 2/3.
Dotted eighth = (60,000 / BPM) × 0.75Reverb pre-delay separates dry signal from wash. Common pre-delays are 1/64 to 1/8 note at song tempo for clarity without rhythmic clash.
Pre-delay ms = (60,000 / BPM) × note fractionUpdated: July 2026
Dotted eighth at 120 BPM ≈ 375 ms — classic U2-style rhythmic delay on guitar.
1/16 note pre-delay ≈ 167 ms keeps vocals intelligible before reverb tail blooms on a slow ballad.
Eighth delay ≈ 234 ms per side in a stereo ping-pong plugin for EDM leads.
Dotted eighth is 0.75 of a beat, not 1.5× quarter ms. Multiply quarter ms by 0.75, or divide beat ms by 4 then multiply by 3.
Multiple plugins add latency. Enable PDC in your DAW so synced delays align with the grid despite processing chain latency.
Tempo-synced delay and reverb create rhythmic depth that sits in the groove. Enter BPM to get millisecond values for quarter, eighth, dotted, and triplet note delays for pedals, plugins, and hardware units.
