Audio Reverb Pre-Delay & Decay Time BPM Sync Calculator
Calculate musically locked pre-delay timings (ms), decay envelopes (RT60), and prevent vocal mud in podcasts, gaming streams, and music production.
โ๏ธ Tempo & Time Meter128 BPM
Recommended vocal pre-delay for 128 BPM: 29.3 ms (1/64). This separates clean consonants from the room tail.

Frequently Asked Questions
Why is Reverb Pre-Delay critical for streamer vocal clarity?
Pre-delay is the time gap in milliseconds between your dry spoken voice and the onset of the reverb reflection tail. Without pre-delay (0ms), the reverb envelope instantly blankets your vocal transients, making speech sound muffled and muddy. Adding a 15ms to 45ms pre-delay lets your consonants articulate crisply before the spatial room ambience blooms.
How is tempo-synced pre-delay calculated?
A standard quarter note at 120 BPM lasts 500ms (calculated as 60,000 รท BPM). A 1/64th note pre-delay is (500 รท 16) = 31.25ms. Syncing pre-delay to musical sub-divisions ensures that reverb reflections breathe in perfect rhythm with background stream music.
What is Reverb Decay Time (RT60)?
Decay time (RT60) is the duration it takes for the reverberant sound pressure level to decay by 60 decibels into silence. Matching decay time to 1/2 note or whole note musical intervals prevents overlapping audio tails from creating frequency masking.
What are Dotted and Triplet notes in delay timing?
A standard straight note is 1.0x. A Dotted note multiplies the duration by 1.5x (holding 50% longer, popular for U2/The Edge style rhythmic delays). A Triplet note multiplies the straight value by 0.667x (playing 3 notes in the space of 2).
