Abstract
A wideband assisted reverberation system has multiple microphones (M1-M3) to pick up reverberant sound in a room, multiple loudspeakers (L1-L3) to broadcast sound into the room, and a reverberation matrix connecting a similar bandwidth signal from the microphones (m) through reverberators to the loudspeakers (L). Preferably the reverberation matrix connects each microphone (m) through one or more reverberators to at least two loudspeakers (L) with cross-linking so that each loudspeaker (L) receives a signal comprising a sum of at least two reverberated microphone signals. Most preferably there is full cross-linking so that every microphone (m) through reverberators to every loudspeaker (L), so that each loudspeaker (L) receives a signal comprising a sum of reverberated microphone signals from every microphone (m).
