SYSTEM AND METHOD FOR RECORDING AND SYNTHESIZING SOUND, AND INFRASTRACTURE FOR DISTRIBUTING RECORDED SOUND TO BE REPRODUCED ON REMOTE PLACE

摘要

PROBLEM TO BE SOLVED: To record sound with high quality and independently of a sampling speed by discriminating selected structure out of common spectral structure and common formant structure in a frame and generating a record including its basic frequency and selected frequency. SOLUTION: After executing sampling allowed to be generated at each 1 ms interval by a sampler 120, basic frequency is extracted by a frame generator 130. The frame generator 130 generates a frame and extracts the basic frequency and the envelope of a spectrum from a sound source 110 through the sampler 120. Then a frame analyzer 140 discriminates selected structure out of common spectral structure and common formant structure in the frame and generates a record including the selected structure and suitable basic frequency. Then the generated record is stored in a 1st storage unit 150.
