Abstract
The invention provides a method and a device for compressing sound data in swf (shock wave flash) files in a batched manner. The method includes enabling processing threads to judge whether source swf files contain uncompressed sound data or not; directly storing the source swf files in storage equipment if the source swf files do not contain the uncompressed sound data, and then turning the processing threads into idle threads; enabling the processing threads to execute compression operation on the uncompressed sound data to obtain swf files which only contain compressed sound data if the source swf files contain the uncompressed sound data, then storing the obtained swf files into the storage equipment, and turning the processing threads into idle threads. The processing threads are responsible for the corresponding source swf files. By the method and the device, the sound data in the swf files can be compressed in the batched manner, accordingly, the size of each swf file is effectively reduced, occupied hard disk space is reduced, and the file propagation speed is increased. Besides, the method and the device have the advantage of high compression efficiency.
