Title: METHOD OF EDITING AND REPRODUCING COMPRESSION AUDIO DATA
Abstract:
When dividing audio data, that is constituted on a frame basis having a header at the head thereof and is data-compressed in a format in which data corresponding to a frame is present also outside that frame, into two, front-part audio data and rear-part audio data, at a desired location, at least one of the following processings is performed; (1) appending data of first specified bytes of the rear-part audio data to the end of the front-part, (2) locating data of last specified bytes of the front-part audio data in front of the start of the rear-part audio data, whereby no abnormal noise is produced even by compression data, represented by such as MP3, in which a frame does not always agree with a location of data used by that frame. In addition, two pieces of audio data obtained by dividing originally one piece of audio data can be continuously reproduced with no seam.
