针对传统音频控制器信号检测耗时过多,误差较高的问题,提出基于小波变换的嵌入式音频控制器信号自动检测方法。通过对嵌入式音频控制器信息特征进行采集,对相似特征信息进行匹配处理,并规范相似特征层级,以便对不同层级信息进行分层检测,简化检测步骤。为提高检测精度,进一步对音频控制器嵌入信息进行降噪处理,提高检测精度。最后通过实验证实,基于小波变换的嵌入式音频控制器信号自动检测方法比传统方法有更高的精确度,耗时少,充分满足研究要求。

To solve the problem of time consuming and high error in traditional audio controller signal detection,an embedded audio controller signal automatic detection method based on wavelet transform is proposed.By collecting the information features of the embedded audio controller,the similar feature information is matched,and the similar feature level is standarded to hierarchically detect the different levels.In order to improve the detection accuracy,the embedded information of the audio controller is further denoised,and the detection accuracy is improved to realized the automatic detection of the embedded audio controller signal.Finally,experiments show that the automatic detection method of embedded audio controller based on wavelet transform has higher accuracy than the traditional method,and the time-consuming is significantly reduced,which fully meets the research requirements.
