Abstract

A common goal of most spatial audio techniques is to reproduce the precise location and size of sound sources. Ambisonics is a well-established spatial audio technique that renders sound sources with increasing accuracy as the Ambisonics’ order in-creases. Recently, a novel spatial audio format that replaces spherical harmonics with a set of functions based on wavelets has been proposed. The Spherical Wavelet Format (SWF) aims to improve Ambisonics localization, especially at low orders. In this thesis, a study investigates the perceptual spatial properties of both techniques by means of a set of MUSHRA tests.
