Data compression apparatus, the data compression program, the data compression system, method data compression, data decompression device, data compression and decompression system, and a data structure of compressed data
PROBLEM TO BE SOLVED: To provide a data compression apparatus, a data compression program, a data compression system and a data compression method that improve the efficiency of data compression.;SOLUTION: A data compression/expansion apparatus samples, for example, an audio signal at a predetermined period to acquire sampling data, and converts it to frequency domain data. The data compression/expansion apparatus divides the sequence of converted frequency domain data into a plurality of blocks each containing a variable number of pieces of data, and compresses each block.;COPYRIGHT: (C)2014,JPO&INPIT
