Abstract
Methods and devices for correcting warping in spatial audio may include identifying a geometric transform that defines a geometric warping between a first spatial geometric model that represents how sound is produced in a first volumetric space and a second spatial geometric model that represents how sound is produced in a second volumetric space different from the first volumetric space. The methods and devices may include determining an inverse of the geometric transform that compensates for the geometric transform. The methods and devices may include applying the inverse of the geometric transform to a first location in the first spatial geometric model by mapping the first location to a second location in the second spatial geometric model to correct for the geometric warping.
