Audio signal processing method and apparatus

Abstract

The present disclosure provides an audio signal processing method and an apparatus thereof. The method includes: obtaining M subbands of an audio signal; determining N group scale factors corresponding to N groups of subbands based on M scale factors corresponding to the M subbands, the N groups of subbands being obtained by grouping the M subbands; obtaining M normalized scale factors by a normalization of the M scale factors using the N group scale factors; and generating a bitstream of the audio signal. The disclosure is designed to improve audio signal compression, reduce transmission overheads and improve transmission accuracy.
