Abstract:
A sound compression/decompression system which compresses and decompresses sounds, frame by frame, the system comprising:a sound compression processing module which, for a first frame for which special processing is performed, sets to a special state an index within a bit stream to be transmitted by the first frame and transmits the first frame for which said special processing is performed, and which, for a second frame for which said special processing is not performed, does not change an index within a bit stream to be transmitted by the second frame and transmits the second frame for which said special processing is not performed; anda sound decompression processing module which references the index within said bit stream and performs said special processing for the first frame and does not perform said special processing for the second frame,wherein, for the first frame for which said special processing is performed, said sound compression processing module sets the index value within the bit stream transmitted by the first frame to a value not used during normal compression operation.
