Abstract:
Example embodiments disclosed herein relate to content-adaptive surround sound virtualization. A method of virtualizing surround sound is disclosed. The method includes receiving a set of input audio signals, each of the input audio signals being indicative of sound from one of different sound sources, and determining a probability of the set of input audio signals belonging to a predefined audio content category. The method also includes determining a virtualization amount based on the determined probability, the virtualization amount indicating to which extent the set of input audio signals is virtualized as surround sound. The method further includes performing surround sound virtualization on two or more input audio signals in the set based on the determined virtualization amount and generating output audio signals based on the virtualized input audio signals and other input audio signals in the set. Corresponding system and computer program product for virtualizing surround sound are also disclosed.
