Reverb & Delay Time Calculator
Time-based effects like delay and reverb shape depth, space, groove, and clarity. But dialing timing by ear can be hit-or-miss—especially when you want effects to lock to the tempo.
This calculator converts BPM → milliseconds instantly across common and advanced subdivisions (including
1/64 and 1/128). Perfect for setting:
- Reverb pre-delay
- Slapback & short delays
- Vocal throws
- Synth/pad ambience
- Ping-pong & stereo delays
- Micro-rhythmic FX accents
How to Use the Calculator
- Enter your track’s BPM
- Choose a subdivision
- Copy the millisecond value
- Paste it into your delay or reverb plugin (ms mode)
Most plugins let you switch between sync (beats) and ms. This tool is built for ms mode.
REVERB & DELAY TIME CALCULATOR
Formula: 60000 ÷ BPM = quarter-note (ms). Timing: Straight = ×1, Dotted = ×1.5, Triplet = ×⅔.
Why Time-Matching Matters
When delay and reverb times relate to your track’s BPM, the mix feels tighter, cleaner, and more intentional. Instead of adding mud or washing out details, your effects support the groove and improve clarity.
- Cleaner vocals
- Clearer rhythm & groove
- Reduced masking
- Better transient definition
- More intentional sense of space
Recommended Uses
🎤 Vocals
Use pre-delay (20–80 ms) or 1/4-note / 1/8-note delays to keep vocals forward without getting washed out.
🎸 Guitars
Perfect for slapback (80–140 ms), rhythmic echoes, and width.
🎹 Synths / Pads
Use timed pre-delays for clarity and movement.
🥁 Drums
Sync delays with hi-hats, snares, or percussion for tight rhythmic motion.
Tips & Tricks
- Slapback delay: 80–140 ms for vintage vocals
- Pop vocals: 1/4-note or 1/8-note delays for clarity
- Triplets: great for movement without clutter
- EDM buildups: 1/4-note or 1/2-note delays feel huge
- Lo-fi color: try slightly off-grid timings
- Pre-delay sweet spot: 20–60 ms keeps vocals clean
