An Onset-Guided Spatial Analyser for Binaural Audio

Summary

Ben Supper

Ben has now successfully completed his PhD at the Institute of Sound Recording; the work was supported by Pharos Communications.

Objectives

A novel system of computer algorithms is formulated to perform onset-guided source localisation using binaural stimuli. This system, called the spatial analyser, is intended to analyse spatial attributes besides source location. It is designed to be computationally efficient, to be compatible with streamed binaural data, and to use psychophysically-valid analysis techniques wherever possible. The main components of the system are a model of the human auditory periphery, an onset detector, a running localisation algorithm, and appropriate logic to combine these.
