When considering the acoustics of a room as a linear time-invariant system, the room impulse response (RIR) describes the response of the room to an audio signal from a given source position to a given receiver position. If the RIR is perfectly known, the response of the room to any acoustic signal can be predicted. In practice, however, there are several difficulties. For a reverberant room, a finite impulse response (FIR) representation of the RIR can be on the order of 100 000 samples. Considering the position dependence of the RIR, the complete description of a room requires the RIRs for a multitude of closely spaced source and receiver positions. This is problematic from both ... toggle 2 keywords
