BPM to Delay Time (ms)
Set your song tempo and choose a note value to get perfectly synced delay times for guitar pedals, plugins, and DAWs.
Delay Time (ms) to BPM
Tap Tempo
Tap at least 2 times to detect BPM. Spacebar also works.
What is a delay tempo calculator?
A delay tempo calculator converts BPM (beats per minute) into milliseconds so your delay repeats land in time with the music. Instead of guessing knob positions, you can dial exact values like 500 ms, 375 ms, or 250 ms depending on whether you want quarter notes, dotted eighths, triplets, or faster rhythmic echoes.
This is especially useful for guitarists, synth players, and mixing engineers. Rhythmic delay sounds tight and musical when repeats lock to the song grid; it sounds messy when delay timing drifts off-beat.
The core formula
The basic timing formula is simple:
Delay Time (ms) = (60,000 ÷ BPM) × note value multiplier
- Quarter note multiplier = 1
- Eighth note multiplier = 0.5
- Dotted eighth multiplier = 0.75
- Eighth triplet multiplier = 0.333...
Example at 120 BPM: quarter note is 500 ms, eighth note is 250 ms, and dotted eighth is 375 ms.
Which note value should you use?
Straight note delays
Straight values (quarter, eighth, sixteenth) feel stable and predictable. They work great for clear pop parts, ambient layers, and modern worship textures.
Dotted delays
Dotted values create forward motion. The dotted eighth is famous for creating a cascading rhythmic pulse that fills space without stepping on lead lines.
Triplet delays
Triplets add swing and movement. They are great for blues, funk, and anything needing a less rigid feel than straight-grid repeats.
Practical mix tips for better delay
- High-cut the repeats: darker echoes stay out of the way of vocals and lead instruments.
- Use less feedback than you think: too many repeats quickly clutter a mix.
- Automate wet level: push delay in transitions, pull it back in verses.
- Pan creatively: stereo ping-pong delays can open up a narrow arrangement.
- Combine with reverb carefully: shorter delays often pair better with long reverb tails.
Common use cases
Guitar: Sync dotted eighth for rhythmic picking lines; use quarter for solos.
Synths: Try eighth or triplet echoes for arpeggios and plucks.
Vocals: Use subtle quarter or eighth slap-style echoes to add depth.
Podcast and voice work: Usually use very short delays or none; if used, keep timing subtle and filtered.
Final takeaway
A delay tempo calculator removes guesswork. Start with your BPM, choose a subdivision, and fine-tune by ear for groove and clarity. Numbers give you a reliable starting point; musical context gives you the final answer.
