1. TECHNICAL FIELD OF THE INVENTION;A method of parallel processing audio compression algorithms.;2. The technical problem to be solved by the invention;In order to process audio signals in real time, it is intended to provide a parallel processing method of an audio compression algorithm that performs compression using parallel processing while communicating using parameters.;3. Summary of Solution to Invention;A first step of receiving data and delivering the data to two programs respectively; A second step of extracting a pure tone component of a signal and extracting a noise component after performing a fast Fourier transform process; A third step of calculating a scale factor value and scale factor selection information after analyzing the subbands; Calculating a signal to mask ratio after calculating the masking threshold; And a fifth step of quantizing the subbands and generating a bit string after performing bit allocation.;4. Important uses of the invention;Used for real time processing of MPEG audio compression algorithms.
