Claims17
A surround sound virtualization apparatus, comprising:
- an audio decoder to perform head-related transfer function (HRTF) filtering;
- and
- a time delay unit to provide a time delay to a plurality of output signals of the audio decoder.
A surround sound virtualization method, comprising:
- extracting a plurality of channel signals from an encoded bit stream;
- performing HRTF filtering with respect to the plurality of extracted channel signals;
- transforming the plurality of filtered signals into a time domain;
- and
- providing a time delay to the plurality of signals transformed into the time domain.
