回声消除功能源代码
附件称号:acoustic_echo_cancel压缩包内文件格式:可执行文件
附件来历:互联网
运行方式:Windows方式
是不是经自己验证:是
附件性质:免费
详细说明:该代码是从SPEEX中提取出来相关回声响讯部分的源码
它采纳的是在频域进行操作,效果比较好
经测试,如果原始声响与用于回声响讯的参考声响之间存在时钟不同步时,
很容易生成在回音消息算法中的反溃发散景象
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。
left.pcm:8k16bitlinearpcm,从Input_exsample_stereo.pcm中分离出来的左声道音频。
right.pcm:8k16bitlinearpcm,从Input_exsample_stereo.pcm中分离出来的右声道音频

The file format in the compressed package: executable file
Attachment source: Internet
Operation mode: Windows mode
Is it verified by yourself: yes
Attachment nature: free
Detailed description: This code is the source code of the relevant echo signal part extracted from SPEEX
It adopts the operation in the frequency domain, and the effect is better
After testing, if there is a clock mismatch between the original sound and the reference sound used for the echo sound,
It is easy to generate the anti-collapse divergence in the echo message algorithm
The compressed package contains test voice files:
Input_exsample_stereo.pcm: 8k16bit linear pcm, including dual-channel voice.
left.pcm: 8k16bitlinearpcm, left channel audio separated from Input_exsample_stereo.pcm.
right.pcm: 8k16bitlinearpcm, the right channel audio separated from Input_exsample_stereo.pcm
