In the words of Death By Audio:

ROOMS is a stereo, multi function digital reverb capable of searing volume, gated walls of sound, and long, trailing reverberant ambiances with an intuitive array of controls designed with live mood-bending in mind.

ROOMS was designed to the highest standards of flexibility and audio fidelity. A studio-quality mixer section provides independent DRY and FX controls over six meticulously programmed reverb algorithms; ROOM, DIGIT, PEAK, GATE, WAVE, and GONG. Each different verb is capable of a universe of sounds, and we help you explore them.
