1.
It gets the incidental background noise characteristics of the sample audio by wavelet de-noising,and compares it with the background noise of other audio to detect whether it is tampered by another piece of audio recorded by another type of device,which provides the evidence for judicial authentication.
利用小波降噪得到音频的噪声,以该噪声作为设备的特征本底噪声,与需要检测的音频本底噪声做比对,以检测该音频文件中是否被篡改入由其他种类设备录制的音频,从而为司法鉴定提供判断的依据。
3) noise background

The result shows that the S/N ratio can be raised and the seismic noise suppressed with nonintegerorder calculus.
初步分析表明,借助非整数阶微积分来改变地震数据的分维值、压制地震噪声是可能的。
