Problems solved by technology

However, in practical applications, the staff usually cannot monitor the sound all the time, and cannot find the problems of the equipment to be diagnosed in time, thus failing to achieve the purpose of monitoring
[0004] It can be seen that the existing manual detection method for diagnosis is not only time-consuming and laborious, but also ineffective, and it is almost impossible to realize in a large system

Embodiment Construction

[0022] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the embodiments and accompanying drawings.

[0023] In the existing audio quality diagnosis scheme, manual diagnosis is used to diagnose whether the equipment to be diagnosed is faulty, and the staff monitors the collected audio signals. However, in practical applications, the staff usually cannot monitor the sound all the time, and cannot find the equipment to be diagnosed in time Existing problems, and then can not achieve the purpose of monitoring.

[0024] In order to solve this technical problem, the present invention obtains the source audio from the device to be diagnosed, collects the audio played by itself, and obtains the test audio, and further determines whether there is a fault in the audio function of the device to be diagnosed according to the correlation between the source audi...

Abstract

The invention discloses a method and device for audio quality diagnosis, wherein the method includes: acquiring source audio, starting a playback module of the device to be diagnosed to play the source audio; collecting and playing the audio, expressed as a test audio; calculating the source audio and the test audio Correlation, to get the correlation value; judge whether the correlation value is greater than the correlation threshold, if not, determine the fault of the equipment to be diagnosed. The solution of the invention can automatically and intelligently diagnose the audio quality.

Description

technical field [0001] The invention relates to audio processing technology, in particular to a method and device for audio quality diagnosis. Background technique [0002] During the use of the audio device in the device to be diagnosed, due to aging, electromagnetic interference, and some human factors, the audio device cannot operate normally. In the following, the equipment to be diagnosed in the video surveillance system is taken as an example for description. The equipment to be diagnosed is specifically an IP camera (IPC, IP Camera), a digital video recorder (DVR, Digital Video Recorder) and the like. [0003] In the video monitoring system, the equipment to be diagnosed collects sound signals, and performs sound monitoring based on the collected audio. During monitoring, monitoring personnel listen to the collected audio signals to monitor the sound of the corresponding scene; however, during use, due to various factors, the audio device in the equipment to be diagn...
