SingleRoomSRIR
Spatial room impulse responses (SRIRs) measured with an arbitrary number of receivers (R>1, such as a microphone array) and an omnidirectional source (E=1) in a single room.
SingleRoomSRIR is the standardized version of the previously proposed SingleRoomDRIR.
The conventions is defined in AES69-2020 (SOFA 2.0).
