Abstract

The invention provides an audio signal processing method and device and a storage medium. The audio signal processing method comprises the following steps: acquiring a current frame audio signal as a first audio signal; performing first automatic gain processing on the first audio signal to obtain a second audio signal, wherein the first automatic gain processing specifically comprises: segmenting the first audio signal into audio signals of a plurality of first subframes, calculating a first parameter value according to the audio parameter of each first subframe, comparing the first parameter value with a first threshold interval, obtaining the number M of the subframes of which the first parameter value is not in the first threshold interval, and when M is greater than the first statistical number of times, performing signal gain on the sample points of the first audio signal at the same time. According to the invention, the sample points of the first audio signal are gained at the same time, so that the dynamic range of the audio is kept, the sense of fluctuation of the audio volume is kept, and the voice quality can be improved.

Description

technical field [0001] The present invention relates to the field of audio technology, in particular to an audio signal processing method, device and storage medium. Background technique [0002] With the widespread use of modern communication technology, the competition among communication companies is intensifying. In order to enhance their own competitive advantages, communication companies need to improve the quality of their communication signals and improve the stability, security, and efficiency of various indicators of the communication system. sex. [0003] In the implementation of the audio signal processing method, the automatic gain control algorithm (AGC) algorithm is adopted, which can improve the stability of the audio signal system and audio signal output, and solve the signal distortion problem after AGC debugging. At present, many AGCs (Automatic Gain Control Algorithm) process each point in a frame of speech signal point by point, which will lead to the l...
