jagger2048 / webrtc_noise_suppression Goto Github PK

我想请问下，如果不使用文件输入数据，而是实时进行处理的话应该如何修改，因为它会保留之前帧的信息，我在实时处理时的效果始终不对。

Hi I wonder if there could be more info on how to install and compile this tool in documentation? Thanks

Hello jagger2048,

I am a beginner of c language.
I am confused about how to compile your project and run it.
Could you please give me some information about it?
Thank you!

Hi,

Thank for your value repository.

I wondering your module support multiple-channel input for noise suppression?

Hello, jagger2048!
Thank You for Your great project!

In documentation for signal_processing_library.h I found this words:
// WebRtcSpl_AnalysisQMF(...) // // Splits a 0-2*F Hz signal into two sub bands: 0-F Hz and F-2*F Hz. The // current version has F = 8000, therefore, a super-wideband audio signal is // split to lower-band 0-8 kHz and upper-band 8-16 kHz. // // Input: // - in_data : Wide band speech signal, 320 samples (10 ms) // // Input & Output: // - filter_state1 : Filter state for first All-pass filter // - filter_state2 : Filter state for second All-pass filter // // Output: // - low_band : Lower-band signal 0-8 kHz band, 160 samples (10 ms) // - high_band : Upper-band signal 8-16 kHz band (flipped in frequency // domain), 160 samples (10 ms)

So why do You use WebRtcSpl_AnalysisQMF(...) (and WebRtcSpl_SynthesisQMF(...)) for 32000 Hz sound?
