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
