Spatial Impulse Response Rendering (SIRR) can be used to reproduce room acoustics with any multichannel loudspeaker system. In SIRR the time-dependent direction of arrival and diffuseness of measured room responses are analyzed within frequency bands. A multichannel response suitable for reproduction with any chosen surround loudspeaker setup is synthesized using the analysis data. The resulting loudspeaker responses are used in a multichannel convolving reverberator, and the synthesized responses create a natural perception of space corresponding to the measured room.
The following table lists most important papers on SIRR in inverse chronological order. For some publications, the PDF-file and a companion web-page containing sound
examples are provided. These can be found in the leftmost column.

"Spatial Impulse Response Rendering II: Reproduction of Diffuse Sound and Listening Tests" Journal of the Audio Engineering Society, vol 54, no. 1, 2006
|
The assumptions made in the first SIRR-JAES paper are bolstered here, and a new method to diffuse sound is presented. The quality obtained with SIRR and Ambisonics is studied with formal listening tests in anechoic chamber and in listening room. |

|
A comprehensive description of the SIRR method with some
psychoacoustical background. The described implementation is based on
energetic analysis of a sound field using B-format microphones. The
operation of SIRR is illustrated with an application example.
