Decorrelation for Audio Object Coding

Abstract: 

Object-based representations of audio content are increasingly
used in entertainment systems to deliver immersive and
personalized experiences. Efficient storage and transmission
of such content can be achieved by joint object coding algorithms
that convey a reduced number of downmix signals
together with parametric side information that enables object
reconstruction in the decoder. This paper presents an
approach to improve the performance of joint object coding
by adding one or more decorrelators to the decoding process.
Listening test results illustrate the performance as a function
of the number of decorrelators. The method is adopted as part
of the Dolby AC-4 system standardized by ETSI.
