SingleRoomSRIR
Jump to navigation

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.
SingleRoomSRIR is the standardized version of the previously proposed SingleRoomDRIR.
Version 1.1
The conventions' version is defined in AES69-2022 (SOFA 2.1).
