Audio data reproducing method and program therefor
First Claim
1. An audio data reproduction method for interrupting current reproduction of first audio data, for reproducing second audio data targeted to be reproduced simultaneously within a same certain time period of first audio data reproduction, said method causing a computer having a storage device to self-perform a process comprising:
- at the time period, temporarily interrupting the first audio data reproduction, and beginning reproducing the second audio data;
recording within said time period, the first audio data to said storage device while reproducing the second audio data only;
after completion of reproduction of said second audio data, resuming reproducing said first audio data while forcing a reproduction speed of the first audio data reproduction to increase with elapse of time; and
planning a reproduction start time point of third audio data to be reproduced after completion of the reproduction of said second audio data;
calculating a reproduction end time point of said second audio data;
calculating a gap time being a time period of from said reproduction end time point to said reproduction start time point;
calculating a reproduction time needed for reproduction of said first audio data while increasing the reproduction speed thereof;
determining whether the calculated reproduction time is less than or equal to said gap time; and
only in a case where said reproduction time is less than or equal to said gap time, reproducing said first audio data while increasing said reproduction speed.

Abstract
Regarding first and second audio data to be reproduced simultaneously within a certain time period, a computer which has a storage device records the first audio data to the storage device within the period while at the same time reproducing only the second audio data, and, after having reproduced the second audio data, reproduces the first audio data while forcing its playback speed to increase with time. Whereby, the computer enables the two sets of audio data being reproduced simultaneously to be output in such a way as to provide a listener with enhanced audibility.

3. An audio data reproduction method for interrupting current reproduction of first audio data, for reproducing second audio data targeted to be reproduced simultaneously within a same certain time period of first audio data reproduction, said method causing a computer having a storage device to self-perform a process comprising:
-
at the time period, temporarily interrupting the first audio data reproduction, and beginning reproducing the second audio data; recording within the time period, the first audio data to said storage device while reproducing the second audio data only; after completion of reproduction of said second audio data, resuming reproducing said first audio data while forcing a reproduction speed of the first audio data reproduction to increase with elapse of time; and wherein said computer is built in a movable body and comprises a present position acquisition device operative to acquire a present position of said movable body, said first audio data is added a position relating to said first audio data, and said computer performs; acquiring the present position of said movable body from said present position acquisition device; calculating a distance between the present position acquired and said position added to said first audio data; and exclusively when the distance calculated is less than or equal to a predetermined value, reproducing said first audio data while increasing said reproduction speed. - View Dependent Claims (6)

4. An audio data reproduction method for interrupting current reproduction of first audio data, for reproducing second audio data targeted to be reproduced simultaneously within a same certain time period of first audio data reproduction, said method causing a computer having a storage device to self-perform a process comprising:
-
at the time period, temporarily interrupting the first audio data reproduction, and beginning reproducing the second audio data; recording within the time period, the first audio data to said storage device while reproducing the second audio data only; after completion of reproduction of said second audio data, resuming reproducing said first audio data while forcing a reproduction speed of the first audio data reproduction to increase with elapse of time; and wherein said computer is built in a movable body and comprises a present position acquisition device for obtaining a present position of said movable body and a mobility information acquisition device for acquiring a moving direction and a moving speed of said movable body, said first audio data is added a position relating to said first audio data, and said computer performs; obtaining the present position of said movable body from said present position acquisition device; obtaining the moving direction and the moving speed of said movable body from said mobility information acquisition device; using the present position and the moving direction and the moving speed to calculate a predicted position which is a position of said movable body at termination of the reproduction of said second audio data; calculating a distance between the calculated predicted position and said position added to said first audio data; and only when the distance calculated is less than or equal to a predefined value, reproducing said first audio data while varying the reproduction speed thereof. - View Dependent Claims (7)
