BPM to Delay Time Calculator – Exact Milliseconds for Every Note

How to Use This Free Delay Time Calculator

1. Set your song's BPM using the slider, number box, or by tapping the Tap Tempo button in time with the beat.

2. The table updates instantly and shows the exact delay time in milliseconds for every common note value (straight, dotted and triplet).

3. Click any number to copy it, or turn on Voice Feedback so the tool speaks the value aloud — perfect when you are adjusting a hardware delay pedal.

Unique Feature: Voice Feedback Reads Delay Times Aloud

Most delay calculators only show numbers on screen. This one can speak them. Enable Voice Feedback and tap any value in the table — the calculator reads the millisecond number out loud. This is especially useful when your hands are on a hardware unit or you are working in a dark studio and do not want to look at the screen.

The Exact Formula to Calculate Delay Time from BPM

The core formula is simple:

Quarter note (ms) = 60,000 ÷ BPM

Example at 120 BPM: 60,000 ÷ 120 = 500 ms (one quarter note).

From the quarter note you can derive every other value:

• Eighth note = quarter ÷ 2
• Sixteenth note = quarter ÷ 4
• Dotted note = straight × 1.5
• Triplet = straight × (2/3)

This calculator does all the math for you instantly so you never have to calculate mid-session.

Quick Reference Chart – Most Common BPMs

Here are the most useful delay times for popular tempos (values in milliseconds):

Dotted vs Triplet Delay – When to Use Each

Dotted notes (× 1.5) push the echo later and create a wider, more spacious feel. The classic "Edge" guitar sound is almost always a dotted eighth note delay.

Triplets (× 2/3) lock into swung or shuffled grooves and feel more natural on hip-hop, R&B and some electronic styles.

Rule of thumb: use dotted for big rock/pop anthems, use triplets when the track already has swing.

Best Delay Times for Vocals, Guitars, Drums & Synths

• Vocals: 1/8 or dotted 1/8 for rhythmic interest, short 1/16 for slapback.
• Guitars: Dotted 1/8 is the classic choice (U2, many indie tracks). Triplet 1/8 works great for funk and soul.
• Drums: Short 1/16 or 1/32 for thickening, or a longer 1/4 for ambient tails.
• Synths / Pads: Longer 1/4 or half-note delays for width and atmosphere.

How to Set Reverb Pre-Delay Using BPM

Reverb pre-delay separates the dry signal from the wet tail and keeps the mix clear. A good starting point is between 1/32 and 1/16 of the quarter note.

At 120 BPM a 1/32 note is roughly 62.5 ms and a 1/16 is 125 ms. Start around 20–80 ms for vocals and adjust by ear until the reverb breathes without smearing the words.

Famous Delay Examples

• U2 – The Edge: Almost always dotted eighth notes (at 120 BPM ≈ 375 ms).
• Pink Floyd – Comfortably Numb: Longer dotted quarter-style delays for the big guitar solo.
• Many modern pop & EDM tracks: Straight 1/8 or 1/16 for tight rhythmic repeats.
