摘要
本文主要采用声谱图特征,对广播音频信号进行可视化监测研究,通过实验分析,音频声谱图对广播实时监测能起到有效的保障作用,同时根据声谱图的有效特征参数,我们还能衍生出其他多类型的监控界面,丰富了监测内容,具有一定的实用性。
Based on the video spectrogram,this paper makes a study on the visual monitoring of broadcasting audio signals.Through experimental analysis,it is found that an audio spectrogram is useful in the real-time monitoring of broadcasting signals.Meanwhile,according to the effective characteristic parameters of the spectrogram,we can also derive other types of monitoring interfaces,which have enriched the monitoring content and have certain practicability.
