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.
|N/A||V. Pulkki and J.Merimaa "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.|
|J.Merimaa and V. Pulkki, "Spatial Impulse Response Rendering I: Analysis and Synthesis" Journal of the Audio Engineering Society, vol 53, no. 12, 2005
||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.|

||The SIRR method and an implementation based on energetic analysis of a sound field using B-format microphones are described, and some listening experiments are reviewed.|
|J.Merimaa and T. Peltonen and T. Lokki "Concert Hall Impulse Responses - Pori, Finland,"
||Measurement methods and comprehensive analysis of a set of impulse responses measured in the Pori Promenadikeskus concert hall a presented. All omnidirectional, binaural, B-format, and SIRR processed responses are available for download.|
|V. Pulkki and J.Merimaa "Spatial Impulse Response Rendering: A Tool for Reproducing Room Acoustics for Multi-Channel Listening," white paper for Waves, Inc.
||The basics of SIRR are described. This paper is meant as a introduction to SIRR, and it should be also accessible to people with less background in audio and signal processing.|
