AVS-P10 is a national standard for low bit rate bandwidth extension schemes,but since the standard only uses the high frequency envelope information and the high frequency gain to adjust the high frequency portion of the restored signal,the restored sound quality is poorer. Aiming at this problem,after analyzing the corresponding bandw idth extension principle of AVS-P10,a novel bandw idth extension scheme based on tonality adjustment is proposed. Tonality parameters are extracted from the encoder part in F...
