BPM To Delay Milliseconds Calculator

Turn a tempo into delay, pre-delay and LFO times in milliseconds, hertz and samples for every straight, dotted and triplet note value.

BPM To Delay Milliseconds Calculator converts a tempo into the exact note lengths a track runs on, starting from the one rule everything else follows: a quarter note lasts 60000 ÷ BPM milliseconds. From there it derives straight, dotted and triplet values from a whole note down to a 1/64, and shows each as milliseconds, hertz for LFO rates, and samples for code or plugin automation. It also names the closest note value to a delay time you already have.

Why use BPM To Delay Milliseconds Calculator

• One formula, every value

  Straight, dotted and triplet lengths all come from 60000 ÷ BPM, so nothing drifts.

• Three unit systems

  Milliseconds for delays, hertz for LFOs and samples for buffer or code work.

• Reverse lookup

  Enter a delay time you already have and see which note value it is closest to.

Common use cases

• Dialling a dotted eighth delay for a guitar or synth line — 375 ms at 120 BPM — without guessing.
• Setting an LFO or tremolo to an eighth-note rate by entering the hertz value the plugin asks for.
• Choosing reverb pre-delay of a 1/32 or 1/16 so early reflections land on the grid instead of smearing the transient.
• Checking whether the 380 ms on a hardware delay is close enough to a tempo-synced value or needs nudging.
