Beamforming on Respeaker Core v2

Products & Technology ReSpeaker
#1

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.
