Research on the Key Technologies of Broadcasting Audio Quality Automatic Detection

As an important part of broadcast business, Broadcast audio quality testing guarantee the broadcast quality, it can find out audio quality problem during broadcasting process such as stereo phase inversion, too large of left and right level difference, mute and overload etc. The traditional detection method of artificial technical is time-consuming and laborintensive, which can easily lead to miscarriage of justice and leakage of judgment. This paper is for the above problems, through the specific audio quality check business process analysis, combined with the relevant digital signal processing technology and computer-aided analysis of algorithm design, and through the test experiment completed the audio quality of the automated analysis and processing algorithms to achieve a better analysis and detection effect.
