Embodiment Construction

[0051] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0052] figure 1 Is a flowchart of a noise detection method according to an exemplary embodiment, see figure 1 , The method is applied to the server, including the following steps.

[0053] Step 101: For each frame signal of a plurality of frame signals included in the target audio signal, based on the cut-off frequency of the frame signal, determine the number of subbands included in the frame signal and the frequency domain amplitude average of each subband Value, the target audio signal is the audio signal for noise detection.

[0054] Step 102: Determine the noise detection coefficient of the target audio signal based on the average value of the frequency domain amplitude of each subband in the multiple frame signals.

[0055] Step 103: When ...

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 ...
