There are many things we can test to see what might be going on but a lot of it requires some test gear, if that makes sense. For instance what voltage is at the various pins of the THAT1512 (with respect to ground/0v), especially the output: pin 6 at the device itself so we ...
I know the microphone works, and as of trying to connect it again, I'm using AirPods Pro 2nd Gen. I don't even see the choice for Airpods microphone inside of the Sound setting in Settings, and when I do and test it, it just says 0% total volume detected or something like that,...
Our microphone spec says it’ll be -44 dB compared to 1 volt, with the 0 dB point set at an input of 1 Pascal (or 94 dB SPL). To get the output voltage for a given dB SPL, we can start by simply calculating dB offsets using the sensitivity figure. We’ll get back to 0 dB ...
