MPEG-D Spatial Audio Object Coding for Dialogue Enhancement (SAOC-DE)

Document Thumbnail

The topic of Dialogue Enhancement and personalization of audio has recently received increased attention. Both hearing-impaired and normal-hearing audience benefit, for example, from the possibility of boosting the commentator speech to minimize listening effort, or to attenuate the speech in favor of sports stadium atmosphere in order to enhance the feeling of being there. In late 2014, the ISO/MPEG standardization group made available a new specification, Spatial Audio Object Coding for Dialogue Enhancement (SAOC-DE), which was closely derived from the well-known MPEG-D Spatial Audio Object Coding (SAOC). This paper describes the architecture and features of the new system. The envisioned applications will be discussed and the performance of the new technology is demonstrated in subjective listening tests.
