The ArchLinux wiki as usual is a great source of info.Īlso you have AGC enabled so volume should be automatically levelled digital_gain_control=1 but after that include agc_start_volume=85 as if its too low it never gets a signal to kick in AGC Possible values 0-255. # Use PulseAudio by defaultĭescription "Default ALSA Output (currently PulseAudio Sound Server)" You can also setup as you have and create a nf and all your alsa devices and commands will use pulseaudio and pulseaudio-alsa.

I’m not sure how much doing steering (changing target_direction) dynamically works either. ![]() The webrtc library doesn’t implement DOA. I asked the pulse guys and they kindly replied. The webrtc AEC is really good but its debatable if the beamforming works and how without a differing DoA (Direction of Arrival) What are your setups? Are they working (better than mine, at least)? ![]() Well, the wakeword part if not good (I don’t know if the STT is any better), but standalone recording seem to be good.
