<p>In Fig. 1 , a user selects a plurality of pieces of music data desired to be reproduced concurrently, at an input unit 18 of an audio processing apparatus 16, from music data stored in a storage device 12. A reproducing apparatus 14 reproduces selected music data respectively and generates a plurality of audio signals under the control of a control unit 20. An audio processing unit 24 performs allocation of frequency band, extraction of a frequency component, time-division, periodic modulation, processing and allocation of a sound image, to respective audio signals under the control of the control unit 20. Then the audio processing unit 24 attaches segregation information of audio signals and information on the degree of emphasis to respective audio signals. The down mixer 26 mixes a plurality of audio signals and outputs as an audio signal having a predetermined number of channels, then an output unit 30 outputs the signal as sounds.</p> |
