Abstract
Room acoustics, and perception thereof, is an important consideration in research, engineering, architecture, creative expression, and many other areas of human activity, particularly indoors. Typical room datasets either contain disparate measurements of diverse spaces, e.g., the OpenAir dataset (Murphy and Shelley, 2010), or rich sets of measurements within a few rooms, e.g., CD4M (Stewart and Sandler, 2010). Development of techniques, such as the RSAO, with 6 degrees of freedom (6DOF) movement in media applications require testing distance-related effects. Hence there is a need for consistency across room measurements in terms of source-room-receiver configuration, such as in (Lokki et al., 2011) but particularly for typical rooms. Those available containing ARIRs, BRIRs and with a consistent measurement procedure tend to be limited in range of rooms measured (Bacila and Lee, 2019). We designed an RIR dataset covering a range of rooms, with typical reverberation times, 1O-ARIRs and BRIRs, and regular measurement procedure including source-receiver distances from 1 m to 3 m in 0.5 m intervals. We measured seven rooms including one room with variable acoustics in two configurations – eight total sets. The rooms within this dataset have mid-range RT60s from 0.24 s to 1.00 s and volumes from 50 m3 to 1600 m3. The accompanying paper includes capture methods, various descriptive metrics and a description of applications across diverse domains. The dataset consists of .WAV files for IRs, .PLY files for LiDAR scans and image files for accompanying 3D pictures. IRs are also available in the SOFA format.
