Solved ReSpeaker 4 Mic Array for GA
Recently i bought a ReSpeaker USB Mic Array for my RaspberryPi 4 (8Gb).
I use this Mic for GoogleAssistant (SDK), but it hears me badly.
I decided to check the Mic with next commands:
[ pi@raspberrypi:~ $ arecord test.waw ] — and say some words.
[ Recording WAVE ‘test.waw’ : Unsigned 8 bit, Rate 8000 Hz, Mono
^CAborted by signal Interrupt… ]
[ pi@raspberrypi:~ $ aplay test.waw ] — I hear my words with VERY loud digital noise and interference!
[ Playing WAVE ‘test.waw’ : Unsigned 8 bit, Rate 8000 Hz, Mono. ]
Then i cheked Mic with commands:
[ arecord --format=S16_LE --duration=5 --rate=16000 --file-type=raw out.raw ]
[ aplay --format=S16_LE --rate=16000 out.raw ]
With these commands the sound was PERFECT ! (just some echo).
I suppose that my Mic records sound in bad quality (by defalt), because my GA hardly hears me from distance even 1 metre.
Can you help me with this problem ?
I want to have my GA hearing always with good quality.
If you think, it’s beter to make double post…
