Beamforming on Respeaker Core v2

Hello,



I’m using the latest Debian version on Respeaker Core v2.

I’m recording with the sox tools over alsa (I removed pulse audio).

I’m using the simple .asoundrc file:

pcm.!default {

type asym

capture.pcm “mic”

playback.pcm “speaker”

}

pcm.mic {

type plug

slave {

pcm “hw:seeed8micvoicec,0”

rate 16000

}

}

pcm.speaker {

type plug

slave {

pcm “hw:seeed8micvoicec,1”

channels 2

}

}



I was wondering if with this configuration, I record with beamforming feature from the Respeaker

Or do I have use a more complicated .asoundrc or even the librespeaker library to benefit from some beamforming features?



Thanks for your help

Hi there,



For the beam-forming function, you have to use librespeaker function to enable this function. you can refer to <LINK_TEXT text=“http://wiki.seeedstudio.com/ReSpeaker_C … io-process”>http://wiki.seeedstudio.com/ReSpeaker_Core_v2.0/#librespeaker-aduio-process</LINK_TEXT> thanks.
