About this reverb & echo tool
Reverb and echo are what make recordings sound like they happened somewhere — a room, a cathedral, the inside of a tin can. This tool gives you three quick presets that cover most cases plus a custom mode where you set the delay and decay yourself.

Reverb FAQ
What's the difference between reverb and echo?
Echo is one or more discrete copies of the sound after a delay — you can hear each repetition. Reverb is hundreds of overlapping echoes that smear together into a continuous tail. This tool's presets approximate reverb by stacking multiple echoes; for true convolution-quality reverb you'd want a dedicated DAW plugin.
What's slap-back?
A single short echo (50–150 ms) that sounds like the recording was made in a hard-walled room. Classic 1950s rockabilly vocal sound — Elvis, Buddy Holly, etc.
Will it sound studio-quality?
It uses an echo-based ambience engine, which is fast and good for taste-of-room ambience and slap-back. For lush hall reverb on a vocal, a dedicated plugin (Valhalla, etc.) sounds richer.
Will the audio be re-encoded?
Yes — adding ambience requires re-encoding. The output uses the same format as the input at a sensible quality default.
