//! Parameter sets for simulating different reverberant environments.
//!
//! The tapped delays and tapped gains specify the start of the reverb, and must
//! be the same length. They represent the initial reflection paths, and are
//! used to sculpt the echoes of the room.
//!
//! The comb delays are used to fill out the reverberations and create a steady
//! decay; they sculpt the color of the room.
