REVERB

Simulated space. Pre-delay places the source in the room, decay time sets how big the room is.

Key takeaways

  • Simulated space.
  • Pre-delay places the source in the room, decay time sets how big the room is.
  • Pre-delay separates the source from its tail so words stay intelligible, decay time sets the size, and damping controls how quickly high frequencies die away.
  • 20–40 ms of pre-delay on a lead vocal keeps consonants clear while still placing the voice in a space.
  • Watch out: adding reverb as an insert on every channel.

Quick checklist

  • Can you define reverb in one sentence without looking?
  • Can you point at reverb in a real session, mix or contract?
  • Have you tried the practical move above at least once?
  • Would you catch the common mistake before it costs you a take?
  • Have you opened one of the primary sources below rather than a forum thread?

REVERB IN DEPTH

Reverb simulates the reflections of a space. Pre-delay separates the source from its tail so words stay intelligible, decay time sets the size, and damping controls how quickly high frequencies die away. Sending several tracks to one reverb bus is what makes them sound like they were recorded in the same room.

How it works in practice

20–40 ms of pre-delay on a lead vocal keeps consonants clear while still placing the voice in a space.

The mistake people make

Adding reverb as an insert on every channel. You get many unrelated rooms, more low-mid wash and no sense of a shared space.

WHERE REVERB SITS

Reverb belongs to mixing and mastering in the Sampled music glossary. The processing vocabulary, plus the loudness standards streaming services actually measure you against.

TERMS THAT DEPEND ON REVERB

  • Guitar pedal (stompbox)

    A floor-mounted effect between instrument and amp — overdrive, delay, reverb, modulation. Order matters: dirt early, time-based effects late.
