Beamforming on Respeaker Core v2

Post by frederic.bost » Tue Feb 26, 2019 10:13 am

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 http://wiki.seeedstudio.com/ReSpeaker_C ... io-process thanks.
