该代码是从SPEEX中提取出来有关回声消息部分的源码
它采取的是在频域进行操作,效果比较好"
经测试,如果原始声音与用于回声消息的参考声音之间存在时钟不同步时,极易发生在回音消息算法中的反溃发散现象.
压缩包中含有测试语音文件:
Input_exsample_stereo.pcm: 8k16bit的线性pcm,含双通道语音。
vleft.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的左声道音频。
right.pcm: 8k16bit linear pcm, 从Input_exsample_stereo.pcm 中分离出来的右声道音频。
-The code is extracted from the SPEEX news out of the echo part of the source it is taken to operate in the frequency domain, the effect is better " by the test, if the original voice message and a reference for the echo between the voice of the clock is not synchronized easily occurred in the response message algorithm in the phenomenon of anti-ulcer divergence. compressed package file containing the test voice: Input_exsample_stereo.pcm: 8k16bit linear pcm, including dual-channel voice. vleft.pcm: 8k16bit linear pcm, from Input_exsample_stereo.pcm separate the left channel audio. right.pcm: 8k16bit linear pcm, separated from the Input_exsample_stereo.pcm the right-channel audio.
