SBSBRIR Dataset

Salford-BBC Spatially-sampled Binaural Room Impulse Responses


Available since March 2014

Partnership between the Salford University Acoustics Research and the BBC Audio Research work.



Introduction


A dataset for binaural analysis and simulation of domestic loudspeaker reproduction at multiple listening positions.

SBSBRIR


What is it?

SBSBRIR is a freely-available binaural room impulse response (BRIR) dataset, measured at the University of Salford’s ITU-R BS.1116-compliant listening room. The dataset includes measurements for 12 loudspeakers, positioned at ear-height, using a head-and-torso simulator (HATS) at 15 different positions in the listening area. The HATS was rotated horizontally in 2 degree steps at each position. The dataset can be used in the subjective and objective evaluation of domestic spatial audio reproduction.

BRIR Data

The BRIR data is available to download in several different formats:

Usage


Pre-Requisites

Several external software resources can be installed in order to make use of this dataset.

Simulating the University of Salford Listening Room

SoundScape Renderer's Binaural Room Scanning renderer can be run using the SBSBRIR data, using one of the provided example scenes, e.g.:

ssr-brs sbsbrir-brs-x0y0-ITU5.asd

This creates a binaural simulation of loudspeakers in the University of Salford's listening room. A head tracking system is used with the SoundScape Renderer to give dynamic BRS rendering.

Note that the impulse response files (WAVs) must be stored in the correct directory relative to the scene file. In the examples this is an a directory irs in the same parent directory as the scene file.
