Abstract
A postprocessor mixes audio signals for an LSch and an RSch indicating virtual surround sounds generated by a virtual surround processing unit with audio signals of an Rch, an Lch, and a Cch, performs a high-pass filter process, and then outputs the processed audio signals as audio signals for an Rsp and an Lsp which are main speakers. Further, the postprocessor performs phase inversion on the audio signals for the LSch and the RSch indicating the virtual surround sounds generated by the virtual surround processing unit, mixes the processed audio signals with audio signals of the Rch, the Lch, the Cch, and an LFEch, performs a low-pass filter process on the mixed signals, and then outputs the processed audio signals as audio signals for an SW which is a subwoofer. Thus, in a sound field realized by a virtual surround system, an influence of the sounds emitted from the subwoofer on localization of sounds of channels of virtual speakers is reduced.
