Abstract

The invention discloses an audio detection method and a system. The method comprises the following steps: acquiring an audio stream and pickup front-end information; framing the acquired audio streamand pickup front-end information, and inputting the framed audio stream and pickup front-end information into a corresponding audio detection device; extracting audio performance characteristics in the framed audio stream and the pickup front-end information by a corresponding audio detection device; and detecting the set audio parameters according to the extracted audio performance characteristics, and outputting audio quality single scores associated with the set audio parameters. According to the audio detection method and system provided by the invention, the defect that the audio problemof the sound pickup system can be found only through manual real-time monitoring or after-event backtracking is avoided, and the reliability and stability of the whole security monitoring system are greatly improved; and corresponding channel audio quality information can be provided, so that maintenance personnel can carry out related maintenance conveniently.

Description

technical field [0001] The invention relates to the field of security monitoring, and in particular discloses an audio detection method and system. Background technique [0002] Security monitoring is mainly based on video, and video inspection is relatively easy, and maintenance personnel can confirm whether there are problems in multiple video signals with the naked eye in a short time. However, audio signals play an auxiliary role in security monitoring. Maintenance personnel must use speakers or earphones to play each signal separately to confirm whether there is a problem with the audio signal. It is impossible to check multiple audio signals, and long-term monitoring can easily lead to fatigue. Therefore, In actual operation, monitoring personnel seldom monitor the audio in real time. Generally, when it is necessary to look back at the live video, they will synchronously call the audio to cooperate, so as to better restore the live scene. Therefore, when there is a pr...
