Title:
AUDIO PROCESSOR AND AUDIO PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2008/065731
Kind Code:
A1
Abstract:
In an input section (18) of an audio processor (16) in Fig. 1, a user selects plural music
data to be simultaneously reproduced from the music data stored in a storage (12).
Reproducing devices (14) reproduce the selected music data respectively and
generate plural audio signals under the control of a control unit (20). Under control
of the control unit (20), an audio processing section (24) performs the allocation
of a frequency band, the extraction of a frequency component, time division,
periodic modulation, processing, and localization assignment and adds information
on the separation of the audio signals and information on the degree of emphasis
thereof to the respective audio signals. A down mixer (26) mixes the audio signals
and outputs it as an audio signal having a predetermined number of channels and
an output device (30) outputs it as a sound.
