Re: noise suppression with librespeaker in RespeakerCorev2

Hi Fred,

Can you try to record at first and aplay after it? And the format of pharse.wav should be same as the recordings, which means it should be 16-bit. If pharse.wav is not 16-bit, I think you should use an Alsa plugin to play it.

Re: noise suppression with librespeaker in RespeakerCorev2

Hi Fred, The capture and playback sample rate of seeed voicecard should be the same in Alsa setup. So we have to configure Alsa(edit /etc/asound.conf file) as follow: sudo nano /etc/asound.conf pcm.!default { type asym #capture.pcm "hw:Loopback,1,0" capture.pcm "seeedvoicecard" #playback.pcm "plughw...

Re: noise suppression with librespeaker in RespeakerCorev2

Hi, Thanks for the feedback. Let me explain these nodes in details: (1)hybrid_node: this node provides NS, AGC, VAD algorithms from WebRTC lib, not the Alango, so we are more recommended to use the vep_node. What is more, you can enable NS, AGC, VAD in the same instance in your case, for examples: h...

Re: noise suppression with librespeaker in RespeakerCorev2

"underrun" means the aloop node doesn't send the audio data to the loopback buffer on time. If you got a long list of this, it was probably because the previous nodes didn't send the audio data to aloop node. I think something stuck "vep node" at that time. You can monitor the CPU usage with "htop" ...

Re: noise suppression with librespeaker in RespeakerCorev2

How do you think that if we capture audio via alsa api and redirect the processed audio stream with alsa-aloop? Then snips or other ASRs can capture the processed audio stream easily.

Re: noise suppression with librespeaker in RespeakerCorev2

Hi Cinettoa,

I apologize for my late reply. I am very sorry about this.

Does this new librespeaker2.1.1 work on your board?
For the header files problems, I think you have to remove "/usr/local/lib/pkgconfig/respeaker.pc" manually.

Sincere apology,
Jerry

Re: Respeaker Core v2 and Snips

Hi,

The class SnipsDoaKwsNode is located in librespeaker2.1.0, which is not released yet. A huge update of librespeaker is still developing, and we may release librespeaker3.0.0 directly in late Nov.

Thanks for your attention!
