Mixing with Multiple Reverbs: Creating Depth and Dimension

Why Use Multiple Reverbs?

Using a single reverb on everything puts all elements in the same space. While this can work for some productions, using multiple reverbs allows you to:

Create front-to-back depth
Give each element its own space
Add variety and interest
Maintain clarity while adding ambience

The Three-Reverb Approach

A common professional approach uses three reverbs, each serving a different purpose:

1. Short Ambience (Room/Plate)

Purpose: Adds life and presence without obvious "reverb"

Decay: 0.3-0.8 seconds
Type: Room or short plate
Pre-delay: 0-15ms
Use on: Drums, percussion, acoustic instruments, vocals

2. Medium Hall

Purpose: Creates the "main" space of the mix

Decay: 1.5-2.5 seconds
Type: Hall or chamber
Pre-delay: 30-60ms
Use on: Lead vocals, melodic elements, featured instruments

3. Long Ambient (Hall/Plate)

Purpose: Adds depth and drama for special moments

Decay: 3-6+ seconds
Type: Large hall or lush plate
Pre-delay: 60-100ms
Use on: Sparse arrangements, dramatic moments, pads, effects

Routing and Organization

Aux/Send Setup

Create three stereo aux tracks
Insert one reverb on each, set to 100% wet
Create sends from your source tracks to each aux
Adjust send levels to taste

Color Coding

Color-code your reverb auxes for quick identification:

Short = Green (close, natural)
Medium = Blue (standard, main)
Long = Purple (dramatic, far)

Balancing Multiple Reverbs

The Hierarchy Principle

Not all elements need all reverbs. Create hierarchy:

Lead vocal: Medium hall (primary), short room (subtle)
Drums: Short room (primary), medium hall (subtle on snare)
Guitars: Varies by part and arrangement
Pads/strings: Long hall (primary), medium as needed

Preventing Mud

Multiple reverbs can quickly become muddy. Combat this with:

Aggressive high-pass filtering on each reverb (200-400Hz)
Low-pass filtering to taste (6-12kHz)
Using sends rather than inserts
Automating reverb sends - not everything needs reverb all the time

Advanced Techniques

Depth Staging

Use reverb blend to position elements front-to-back:

Front: More dry signal, less reverb, shorter reverb
Middle: Balanced blend
Back: More reverb, longer decay, less dry signal

Reverb EQ

EQ each reverb return differently:

Short room: More high-end for presence
Medium hall: Neutral, maybe slight high cut
Long ambient: Significant high and low cuts for dreamy quality

Compression on Reverb

Light compression on reverb returns can:

Even out the decay
Add sustain and body
Help the reverb "sit" better in the mix

Conclusion

Multiple reverbs, used thoughtfully, create mixes with depth, dimension, and professional polish. Start with the three-reverb approach and adjust based on the needs of each project.
