I set up my Matrix Voice with the Alexa Demo and it is working fine.
I am testing a little bit.
One question, how should the range of the microfone normally be?
I ask because the wakeword is only detected if I am in a range of ~1m
Is this normal or is there something I can optimize?
Hi, I have a similar problem. For me the range is 1-2 m, not more.
So I’m interested for a solution as well.
As per the short movie shown at https://www.hackster.io/matrix-labs/matrix-voice-running-alexa-demo-in-hands-free-mode-404aa3, it should work up to about 10 m (30 feet).
I had the same problem. Created a .asoundrc file in the home directory.
I am now able to record from 10ft away.
EDIT…added min_dB max_dB
After you create the file, reboot or logout-login and do a test recording with
arecord -d 10 --device=mic_channel8 -r 16000 -c 1 -f S16_LE test.wav
…test with aplay test.wav
Then go to alsamixer and you should see the new “MicArray Master” volume option.
name “MicArray Master”
Worked for me, hope this helps
