Abstract:
1. A method of processing audio to account for the effect of a plurality of related environments on the sound perceived by a listener simulated to be in one of the environments, comprising: providing a first reverberation block for a first environment in which the listener is simulated to be located, the first reverberation block having an input and a multi-channel output; providing 1 to N further reverberation block(s) corresponding to 1 to N further environment(s) related to the first environment, each 1 to N further reverberation block(s) having an input and a multi-channel output; feeding a signal from a sound source into the first reverberation block and the 1 to N further reverberation block(s); determining, for each of the first reverberation block and the 1 to N further reverberation block(s), a reverberation coupling signal; and feeding the determined reverberation coupling signals to the inputs of related ones of the first reverberation block and the 1 to N further reverberation block(s).
