BPM Delay Calculator

Calculate delay times for different note values (milliseconds)

Tip: Use ↑/↓ keys to nudge by ±0.1 BPM

Enter a BPM value to see delay calculations

Tempo Transition Simulator

Simulate musical tempo ramps and see how synced delay times evolve. Pick a note value and curve, then copy milliseconds or export CSV for automation.

Why can a tempo‑synced delay sound like ‘Doppler’?

When tempo changes, a BPM‑synced delay retimes its buffer. Fast retiming can shift perceived pitch or smear transients. Smoother ramps (longer or exponential) or crossfading two delays reduces artifacts.

Lock delay to song tempo

Delay isn’t just ‘echo’; it shapes rhythm and can become part of the groove. The key is aligning delay time to BPM.

By converting note values (quarters, eighths, triplets, dotted) to milliseconds, you can set plugins precisely and stay in sync.

Common recipes

  1. Quarter-note delay: stable foundation, fits many styles.
  2. Eighth or dotted eighth: add breath and forward motion.
  3. Triplets: introduce a tasty off-kilter feel, common in blues/rock.

FAQ

Should stereo delays differ left vs right?

Small offset (10–20 ms) widens the image; using different note values can create call-and-response. Keep main accents aligned to the grid.

Why does my delay feel ‘draggy’?

Check wet/dry balance, pre-delay, and interactions with reverb/compression. Overlong or overwet settings can mask the source.
