Main Ideas / Lessons

  • Film/TV realism is mostly made in post: on set, dialogue (primarily) is recorded; other elements like footsteps, background ambience, sound effects, and music are added later.
  • Dry audio sounds bad / unrealistic: to match an on-screen environment, you must add spatial processing—especially reverb—so sounds “live” in the same acoustic space as the scene.
  • Use reverb in matching pairs: interior vs. exterior
    • Interior reverb for rooms/homes/offices and “inside” moments.
    • Exterior reverb for outdoors/streets/alleys and “outside” moments.
  • Three-reverb workflow (core concept):
    1. Interior reverb
    2. Exterior reverb
    3. A big “5 verb” (dreamy/3D-space) reverb for heightened or stylized moments
  • Make sends/returns do the work:
    • Use send tracks from effect/Foley/background groups to reverb return channels.
    • This allows controlling how much reverb each group receives without needing full reverb per track everywhere.
  • Match spaces consistently across dialogue, backgrounds, and Foley:
    • The same environment should generally have the same reverb logic whether it appears in background ambience, walla, Foley feet, or doors.

Methodology / Setup Instructions

1) Build a template with reverb return channels

Create two reverb return effects:

  • Reverb One = Exterior reverb preset
  • Revive 2 (labeled “Revive 2” in subtitles) = Interior reverb preset

Optionally include a third reverb:

  • “5 verb” = big dreamy reverb Used heavily as an accent tool for stylized “underwater/dream” effects.

2) Route sound to reverbs using sends (for FX / Foley / background groups)

Use sends from tracks/groups to the reverb returns:

  • For each relevant FX/background track:
    • Send to Interior Reverb return
    • Send to Exterior Reverb return
    • Send to 5 verb return (when needed)

He describes the common approach as:

  • Start with send levels set to a baseline (often 0)
  • Raise send amounts only when a sound needs placement in space
  • Emphasize riding the return via send levels, rather than constantly pushing return channels

3) Interior vs. exterior selection logic (how to decide)

  • Match the scene’s environment:
    • If the scene is a cave / large enclosed space → use a bigger interior-like response
    • If it’s outside in a city street (traffic reflections, sirens, dogs, etc.) → use exterior slap/space
  • He also suggests:
    • Interior reverb is typically shorter/less “long” than exterior
    • Exterior has different reflection characteristics

4) Practical example: alleyway “trash bag” SFX

  • Start by listening to the sound dry (no reverb).
  • Add exterior reverb by raising the send to the exterior return.
  • If something pokes out too much (a “hit”/spike):
    • Trim/cut or adjust the timing/portion causing the problem
  • Keep reverb consistent across related material using group control when applicable.

5) Background ambience workflow (different handling than FX)

For backgrounds, he often:

  • Keeps returns at 0 (in the described ambience approach)
  • Adjusts send parameters per background element, so not every track gets equal reverb

He demonstrates:

  • Adding exterior slap to dogs/barking
  • Adding reverb/slap to smaller events (insects/bugs, trash sounds, distant elements)

Then he shows switching to grouped control so multiple background tracks can share the same reverb amount via one adjustment.


6) Foley workflow: feet + environment placement

  • Play Foley feet dry first.
  • Then add:
    • Interior reverb if the footsteps are inside
    • Exterior reverb if outside (alleyway/streets)

He shows realism by:

  • Raising the appropriate return/send amount:
    • Exterior → “outdoors” placement
    • Interior → “room-like” placement (home/office vibe)
  • Testing other behavior styles (e.g., a “parking garage” exterior/interior feel) to match the location.

7) The “5 verb” / dreamy reverb workflow (stylized transitions)

Keep the same send-to-5 verb return setup.

He describes a typical approach:

  • Often keep the 5 verb return near 0
  • Control how much dreamy reverb is applied from the send
  • Demonstrates using EQ roll-off (or another EQ treatment) while increasing the big dreamy reverb
  • Gradually reduce the 5 verb and bring the scene back to “present” / less dreamy

He frames this as ideal for stylized transitions like a gunshot moment or “underwater/dream world” shifts.


8) General guidance / philosophy

  • Use reverb as “glue”: it ties dialogue, effects, backgrounds, and Foley into one cohesive acoustic space.
  • Experiment, but start with proven defaults and quickly match interior/exterior.
  • Reverb choice is subjective, but his two-main-reverb approach has been reliable across many projects.
