Latest Patents
Miyakawa holds a patent for an "Encoding and decoding apparatus causing no deterioration of sound." This innovative apparatus is designed to provide high-quality sound reproduction. The system includes an encoding section and a decoding section, which work together to ensure optimal sound quality. The encoding section features a block length determining section that divides an input signal into blocks based on the degree of change in the signal. Additionally, a frequency band dividing section segments each block's signal into multiple frequency bands. The bit allocating section calculates a masking threshold value-to-noise ratio for each frequency band, determining the number of quantization bits to allocate based on psychoacoustic characteristics. This sophisticated approach allows for the generation of a code string that maintains sound integrity.
