Problems solved by technology
However, the current voice noise reduction method is relatively complicated. For call applications that require real-time data processing, the complex algorithm is not practical, so while reducing the complexity of the calculation, it will affect the final noise reduction effect, so that users cannot get high-quality voice. call experience

The embodiment of the invention discloses an audio signal processing method and device, a server and related equipment, and the method comprises the steps that the audio signal processing device collects a first audio signal and sends first sample information to the server, and the first sample information comprises the first audio signal and a user identification, the server searches a noise analysis model corresponding to the user identifier, and adds the first audio signal to a training sample set; the server performs training by adopting the training sample set to obtain updating information of the noise analysis model; and the audio signal processing device adopts the updating information to update the noise analysis model so as to carry out active noise reduction on the acquired second audio signal. Through the real-time interaction, the server side realizes real-time updating and feedback of the noise analysis model, the audio signal processing device performs active noise reduction processing according to the updated noise analysis model, the voice noise reduction experience effect is improved, in addition, the noise analysis model matched with the user can be determined through the user identifier, and the method and device are more targeted.
Description
technical field [0001] The present invention relates to the field of audio signal processing, in particular to an audio signal processing method, device, server and related equipment. Background technique [0002] Voice communication is frequently performed between users in real life. If the sender is in a noisy environment, the voice signal sent to the receiver will contain noise signals. If the noise is strong, the receiver cannot hear the voice signal of the sender clearly. Therefore, active noise reduction processing needs to be performed on the voice audio recorded by the user. In the prior art, the implementation on the user terminal is as follows: after a user terminal with a voice noise reduction function picks up the noisy voice through the microphone, the signal is processed through the noise reduction technology to obtain a cleaner voice signal, Then, it is transmitted to the user terminal of the receiver through the communication network, and then heard by the ...
