Understanding Reverb Time
Reverb time (RT60) is how long it takes for sound to decay by 60dB. Small rooms need 0.3-0.6s, while concert halls use 1.5-2.5s for rich sound.

Material Absorption Coefficients
Different materials absorb sound differently. Wood absorbs 10-15%, concrete 2-5%, and acoustic foam up to 90% at certain frequencies.

Pre-Delay Settings
Pre-delay is the gap between direct sound and reverb. Use 10-30ms for vocals, 30-60ms for drums, and 60-100ms for large spaces.

EQ Your Reverb
Cut low frequencies (below 200Hz) to avoid muddy reverb. Boost 2-4kHz for clarity and presence in your mix.

Learn how to create perfect acoustic spaces and reverb settings
Room Acoustics Basics:
- Room Volume: Larger rooms create longer reverb decay times naturally
- Surface Materials: Hard surfaces reflect sound, soft materials absorb it
- Room Shape: Parallel walls create standing waves, angled walls reduce them
- Frequency Response: Low frequencies require more absorption than high frequencies
Reverb Type Guide:
- Room Reverb: 0.3-0.6s decay - Natural, intimate sound for vocals
- Hall Reverb: 1.0-2.0s decay - Spacious, classical music ambience
- Plate Reverb: Bright, dense - Perfect for drums and percussion
- Spring Reverb: Vintage character - Great for guitars and surf music
Frequently Asked Questions
RT60 is the time it takes for sound to decay by 60 decibels. It's the industry standard for measuring reverb.
Larger rooms create longer reverb decay times. A 100 sq ft room might have 0.3s reverb, while a cathedral can have 3-4 seconds.
