Message from TC Chair of SPS ( Signal Processing Systems : Design and Implementation ) Professor

Recreating a natural listening experience is the aim of spatial audio reproduction system. Despite the increasing popularity of object-based audio, majority of the legacy audio contents are in channel-based format, which is dependent on the desired playback system. Considering the diversity of today’s playback systems, the quality of reproduced sound scenes degrades significantly when mismatches between the audio content and the playback system occur. To this end, this article introduces an overview of the spatial audio reproduction techniques referred to as primary ambient extraction (PAE) that facilitates the development of an efficient, flexible, and immersive spatial audio reproduction.
