it's the microphone i have posted here before, i just can't get that fucker to work.
At one point i had it working pretty ok, just with a bunch of noise and now i can't get it to output anything, only if i blow air at the mic capsule i can hear the sound output.
i'm starting to think the op amp or the tranny is just shit since i bought it from bug men as they aren't manufactured anymore
The usb ADC works fine, i tried connecting it to my phone via 3.5mm jack and it produces nice and clean sound, so that is not the issue.
Honestly it's fucking frustrating because i am not building a particle collider it's one fucking op amp that is supposed to boost signal from one fucking tranny, thats it.
