A noise detection method and apparatus

Abstract

The invention discloses a noise detection method and apparatus belonging to the technical field of terminals. The method comprises the following steps of: determining, for each frame signal of a plurality of frame signals included in a target audio signal, the number of subbands included in the frame signal and the frequency domain amplitude average value of each subband based on the cutoff frequency of the frame signal, wherein the target audio signal is an audio signal under noise detection; determining a noise detection coefficient of the target audio signal based on a frequency domain amplitude average value of each of the plurality of frame signals; and when the noise detection coefficient is set at a preset threshold interval, determining that the target audio signal is all noise. According to the method and apparatus of the invention, according to the noise detection coefficient determined by the frequency domain average value of the plurality of subbands of each of the plurality of frame signals, the target audio signal is determined to be all noise when the noise detection coefficient is within the preset coefficient threshold interval. The noise detection method and apparatus of the invention do not need operation intervention by working personnel so as to prevent occurrence of missed detection and accordingly raise the noise detection efficiency.

Description

Technical field [0001] The present invention relates to the field of terminal technology, in particular to a noise detection method and device. Background technique [0002] With the advancement of technology and the development of society, people's entertainment life is becoming more and more abundant. Among them, listening to audio information, as an important component of entertainment life, has penetrated into people's lives more and more widely. Because users have higher and higher requirements for the quality of audio information they listen to, and noise usually affects the quality of audio information, in order to meet the user’s listening needs for audio information, it is often necessary to perform the audio information recorded in the server. Noise detection. [0003] At present, the noise detection is usually performed by the staff on the audio information recorded in the server. When the staff detects the audio information recorded in the server, they need to listen ...

Problems solved by technology

[0004] However, due to the large amount of audio information collected by the server, the staff cannot listen to each audio information, resulting in the server may include some audio information that is all messy noise, so that the user can play the audio through the audio application Noise appears during information, which affects the playback effect of audio information and reduces user viscosity
