DEVICE AND METHOD FOR PROCESSING CODED SOUND SIGNAL Russian patent published in 2019 - IPC G01L19/16 

FIELD: data processing.

SUBSTANCE: invention relates to processing of audio signals, in particular, to decoders. Device comprises a demultiplexer which generates basic signal and a set of parameters from the audio information frames, which increases the sampler for upsampling the base signal and outputs the first spectrum with high sampling rate and the next second spectrum with high sampling rate. Both the high-sampling first spectrum and the second high-sampled spectrum have the same content as the base signal, and have a second spectrum width which is greater than the first spectrum width of the base spectrum. Parameter converter for converting parameters of said set of parameters of said access element to obtain transformed parameters and a spectral gaps filling processor for processing said first high-sampling spectrum and said second high-sampling spectrum using said transformed parameters.

EFFECT: high accuracy of decoding parameters, minimizing distortions of signals, reduced computational complexity.
