  Room acoustics measurements are used in many areas of audio research, from
physical acoustics modelling and speech enhancement to virtual reality
applications. This paper documents the technical specifications and choices
made in the measurement of a dataset of spatial room impulse responses (SRIRs)
in a variable acoustics room. Two spherical microphone arrays are used: the mh
Acoustics Eigenmike em32 and the Zylia ZM-1, capable of up to fourth- and
third-order Ambisonic capture, respectively. The dataset consists of three
source and seven receiver positions, repeated with five configurations of the
room's acoustics with varying levels of reverberation. Possible applications of
the dataset include six degrees-of-freedom (6DoF) analysis and rendering, SRIR
interpolation methods, and spatial dereverberation techniques.
