I just got my Matrix Voice today (exciting!), and I am eager to start experimenting.
However, I cannot get either of the two microphone test scripts to function (test_doa.js or test_micarray.js). I suspect this is due to slight differences in low-level configuration between the Creator and Voice microphones, but I’m not sure. I can’t seem to find any other examples in the documentation or in other repos on how to access the Voice microphones via MALOS. The mics do seem to be showing up as ALSA devices (listed as “Dummy”), but I can’t seem to record from them directly either:
arecord --device=hw:1,0 -r 16000 -c 1 -f S16_LE output.wav
This just produced a strange beeping sound (with and without MALOS service running in background).
Is there anything I’m doing wrong at this point? Is there a timeline for some Voice specific examples of accessing the microphone array?
