Reverb pre-delay starting points
Synced delays are step one of a tight mix.
The studio analyzes your actual tracks — tempo, key, structure — and keeps every result in your library, so the numbers are always one click away. Sign up: 3 full packs free.
Frequently asked questions
How do I calculate delay time from BPM?
One beat (a quarter note) lasts 60,000 ÷ BPM milliseconds — 500 ms at 120 BPM. Halve it for an eighth, halve again for a sixteenth; multiply by 1.5 for dotted values and by 2/3 for triplets. The table does all of it for you, at any tempo.
What delay time should I use on vocals?
Common starting points: a dotted-eighth for that pushed, syncopated echo, or a quarter note for a classic slap-back double. Grab the ms value from the table and fine-tune the feedback by ear.
What is reverb pre-delay and how do I set it?
Pre-delay is the gap before the reverb tail starts — it keeps the dry sound articulate. A 1/64 note (or roughly 10–30 ms) tracks the tempo nicely; longer pre-delays push the space further behind the vocal.
What does the Hz column mean?
Frequency is 1000 ÷ milliseconds — useful for tempo-syncing LFOs, auto-pans, and tremolos that want a rate in hertz instead of a time.
