Advancing a Wavelet-Based Spatial Audio Format
This work further develops the theory of Spherical Wavelet Format (SWF), a spatial audio format inspired by Ambisonics that makes use of Spherical Wavelets as a basis to decompose the soundfield. In particular, we have specified a version of SWF that implements a method to build an arbitrary wavelet representation on an arbitrary triangular mesh. We make use of a modified lifting scheme to optimize the interpolating scaling functions for optimal playback reproduction, and we have demonstrateddoi:10.5281/zenodo.7116375 fatcat:aifp47uwqfemndo6thzrfouv5q
