Frequently asked questions
What is reverb?
Reverb (reverberation) is the persistence of sound after it is produced, caused by reflections off walls and surfaces. It gives audio a sense of space — from a small room to a massive cathedral. Adding reverb to dry recordings makes them sound more natural and immersive.
What reverb types are available?
Room (small, intimate space), Hall (concert hall ambience), Cathedral (massive, long decay), Plate (classic recording studio reverb), and Studio (subtle, professional vocal treatment).
Can I add reverb to voice recordings?
Yes — reverb is commonly used on vocals for podcasts, voiceovers, singing, and voice acting. A subtle room reverb makes dry recordings sound natural, while a hall or cathedral reverb creates dramatic atmosphere.
What is the wet/dry mix?
