Reverb
The Studio Ultimate Reverb effect simulates the effect of playing back the source sound in a room of a given size and sound reflectivity. The interval between the arrival of the original sound at the listener’s ears and the first echoes is greater for a large room than a small one. The rate at which the echoes die away depends on both the room size and the reflectivity of the walls.
The presets for Reverb are named for the type of room they simulate – from the passenger cabin of a car all the way up to a huge underground cavern.
