BPM to Delay Time Calculator

Knowledge Base

How to Use the BPM Calculator

Enter your track's BPM (beats per minute) to calculate delay times in milliseconds and samples. This tool shows delay times for every note subdivision, from whole notes down to 32nd note triplets. These values sync reverb tails, delay repeats, and modulation effects perfectly to your track's tempo.

Why Match Delay to Tempo?

When delay or reverb times align with your song's beat, the effect feels musical and cohesive. Misaligned effects sound muddy and unprofessional. A 500ms delay on a 120 BPM track lands cleanly on beat 1. The same delay on 90 BPM will feel rushed and off.

Understanding the Values

• Milliseconds (ms): Plug this directly into your reverb or delay plugin.
• Samples: Used in sound design and tape echo emulations. Depends on your audio interface's sample rate (typically 44,100 or 48,000 Hz).
• Note Divisions: Quarter note, eighth note, triplet eighth, sixteenth, etc. each have different timing values.

Tap Tempo Feature

Click the "Tap BPM" button repeatedly to detect your track's tempo instead of entering it manually. This is faster when eyeballing an unlabeled reference track.

FAQ

Q: Why do some delays feel musical while others sound off?
A: Musical delays sync to a note subdivision of your track, usually a quarter note, eighth note, or dotted eighth. Arbitrary times feel sloppy.

Q: What's the difference between samples and milliseconds?
A: Milliseconds are universal. Samples depend on your session's sample rate. 48 kHz is common in video. 44.1 kHz in music.

Q: Should I always use a dotted eighth note delay?
A: It's popular but not mandatory. Experiment with quarter notes and sixteenth notes depending on the mix.

Worked examples: delay times at common tempos

Delay and reverb settings in milliseconds for the tempos most sessions sit at. Read down the column for your tempo and across for the note value you want the repeat to land on.

A quarter note is always 60,000 divided by the tempo, because there are 60,000 milliseconds in a minute and a quarter note gets one beat. Every other value in the table is that number multiplied by the fraction of a beat the note occupies. The dotted eighth is the classic pop delay, sitting three quarters of a beat behind the note.

Vocabulary

BPM. Beats per minute, the tempo of a piece. At 120 BPM two beats pass every second, so one beat lasts 500 milliseconds. Every delay time on this page derives from that single number.

Delay time. How long a repeat waits before sounding, in milliseconds. Setting it to a note value ties the repeats to the rhythm so they reinforce the groove rather than blurring it.

Dotted note. A note extended by half its own length again. A dotted eighth lasts three quarters of a beat rather than a half, which places its repeats between the main beats and produces the syncopated feel common in pop guitar delay.

Triplet. Three notes played in the space normally taken by two. A triplet subdivision gives a rolling feel where a straight subdivision gives a marching one.
