1. An apparatus comprising:
processing circuitry; and
memory circuitry storing instructions that, when executed by the processing circuitry, cause the apparatus at least to:
obtain one or more values for one or more acoustic parameters for a plurality of locations within a sound space, wherein the one or more values are obtained via at least one of:
an analysis of audio signals, or
a modeling process;
generate an image representing the sound space, where an intensity value for a pixel of the image represents a value for an acoustic parameter at a location, of the plurality of locations, corresponding to the pixel such that data in the image enables the sound space to be rendered; and
provide the image and mapping data associated with the image, wherein the mapping data is configured to, at least, describe how the plurality of locations within the sound space are mapped to pixels of the image.
