	This convention set defines a setup used for measuring Spatial room impulse responses (SRIRs) in a single room with a single excitation source (e.g., a loudspeaker) and a listener containing an arbitrary number of receivers (e.g., a microphone array). The data is represented as FIR filters and the positions of both the source and the listener may vary.
