AUDIO PROCESSING DEVICE AND AUDIO PROCESSING METHOD

摘要

In an input unit (18) of an audio processing device (16) in Fig. 1, a user selects a plurality of music data to be simultaneously reproduced from music data stored in a storage device (12). A reproduction device (14) respectively reproduces the selected music data and generates a plurality of audio signals under control of a control unit (20). Under control of the control unit (20), an audio processing unit (24) performs a frequency band allocation and frequency component extraction, time division, cyclic modulation, processing, and positioning allocation for each audio signal so as to add audio signal separation information and information on emphasis degree. A down mixer (26) mixes a plurality of audio signals and outputs it as an audio signal having a predetermined number of channels. An output device (30) outputs it as an acoustic.
