Reverb & Delay: How to Give Your Mix Space (Without Drowning It)
Reverb and delay turn flat sounds into a three-dimensional record — or into soup. The difference is a few habits.
Use sends, not inserts
Put reverb/delay on their own mixer tracks and send instruments to them. Everything shares the same spaces (cohesion), you control each amount with one fader, and you can EQ or sidechain the effect itself.
Choosing reverb sizes
- Small room (0.3–0.8s): drums, percussion — presence without wash.
- Plate (1–2s): vocals and snares — dense, bright, classic.
- Hall (2–4s): pads, melodies, cinematic moments.
Pre-delay 20–40 ms keeps the dry sound separated from its tail — vocals stay upfront even with big verbs.
Delays: sync to the beat
Set delay times in note values, not milliseconds: 1/4 and dotted-1/8 are the workhorses. A dotted-1/8 ping-pong on a vocal or pluck adds instant width and motion. Keep feedback low (2–4 repeats).
Keep it clean
- High-pass every reverb/delay return at ~250 Hz — low-end wash is invisible mud.
- Low-pass returns around 8 kHz to push spaces behind the dry signal.
- Sidechain the reverb to the dry vocal so the tail blooms between phrases.
- In half-time genres, less is more — drill menace comes from dryness.
Frequently asked questions
Should I use reverb as a send or insert?
Send. Shared reverb returns glue the mix, save CPU, and let you EQ and duck the space independently of the dry sound.
What delay time should I use?
Tempo-synced note values — 1/4 and dotted-1/8 fit almost everything. Millisecond delays are for special effects and slapback.
Why does reverb make my mix muddy?
Un-EQ'd returns pile low-mid energy under everything. High-pass reverb returns around 250 Hz and use pre-delay so tails stay behind the dry signal.
