Audio signal processing system
First Claim
1. An audio signal processing system including audio signal reproducing devices which respectively reproduce different sound contents in a plurality of areas including a predetermined area, said audio signal processing system further comprising:
- a receiving section which receives a plurality of audio signals having the different sound contents respectively;
a process period specifying section which specifies a silent period in other audio signals except a particular audio signal for reproducing a sound content in the predetermined area that are received by the receiving section, respectively;
a sound volume level adjusting section which decreases a sound volume level of the particular audio signal, in a period specified by the process period specifying section as a silent period in any of the other audio signals; and
an outputting section which outputs the particular audio signal whose sound volume level is adjusted by the sound volume level adjusting section, whereinthe different sound contents respectively include a contents identifier, andthe audio signal processing system further comprises an identifying section that discriminates whether the received sound content is reproduced in the predetermined area or areas other than the predetermined area.

11. An audio signal processing system including audio signal reproducing devices which respectively reproduce different sound contents in a plurality of areas including a predetermined area, said audio signal processing system further comprising:
-
a receiving section which receives a plurality of audio signals having the different sound contents respectively; a process period specifying section which specifies a silent period in other audio signals except a particular audio signal for reproducing a sound content in the predetermined area that are received by the receiving section, respectively; a frequency characteristic correcting section which executes either a process of removing a predetermined frequency band component from the particular audio signal or a process of correcting the particular audio signal into an audio signal having a frequency characteristic that is similar to the other audio signals, in a period specified by the process period specifying section as the silent period in any of the other audio signals; and an outputting section which outputs the particular audio signal whose frequency characteristic is corrected by the frequency characteristic correcting section, wherein the different sound contents respectively include a contents identifier, and the audio signal processing system further comprises an identifying section that discriminates whether the received sound content is reproduced in the predetermined area or areas other than the predetermined area. - View Dependent Claims (12, 13, 14)

15. An audio signal processing system including audio signal reproducing devices which respectively reproduce different sound contents in a plurality of areas including a predetermined area, said audio signal processing system further comprising:
-
a receiving section which receives a plurality of audio signals having the different sound contents respectively; a process period specifying section which specifies a silent period in a particular audio signal received by the receiving section; an audio signal generating section which generates a second audio signal with respect to the particular audio signal, in a period specified by the process period specifying section as the silent period in the particular audio signal; and an outputting section which superposes the second audio signal on the particular audio signal to output a resultant audio signal, wherein the different sound contents respectively include a contents identifier, and the audio signal processing system further comprises an identifying section that discriminates whether the received sound content is reproduced in the predetermined area or areas other than the predetermined area. - View Dependent Claims (16, 17, 18, 19, 20)
