Исследование параметров эффективности сжатия аудиоданных

In the article the authors offer an original model in which audio signals are compressed on the basis of psychoacoustic properties of hearing: namely, sample length and sampling frequency of audio data that the authors refer to in frequency analysis. The necessary conditions are determined, which allow restoring the sound signal quite accurately, after its digital processing and application of frequency discrete orthogonal transformations to the samples of the primary digital signal. The researchers provide recommendations for values of the examined parameters so that compression could be effective, particularly, the conversion interval and the sampling frequency of the audio signal. The calculation for different frequency ranges of audio signals is performed. The ways for further research of the sampling frequency are identified that take into account psychoacoustic peculiarities of human hearing.
