TH167966B - Methods, machine sets and coding / decoding systems - Google Patents

Abstract

The nature of this invention provides a method, a set of coding / decoding systems based on the coding method. Processing to resolve the stress condition is performed on the full band signal using parameters. Corrective stress correction determined by the characteristic factor of the input audio signal and then The full band signal is coded and sent to the decoder for the decoder to perform the processing. Decode to resolve the stress condition corresponding to the full band signal according to the characteristic factor of Audio input signal and restore audio input This solves problems in the traditional Renaissance. That the audio signal restored by the decoder is likely to have signal distortion, and performs Processing to correct the accentuation condition of the full band signal according to the characteristic factor of Audio signal to improve the coding performance so that the input audio signal is restored by the decoder. The code is quite sharp and closer to the original signal.
