Could I build a metal detector with USB sound cards which is for

signal generation
oscilloscope stuff
FFT/DSP analysis
multichannel audio

So theoretically you can do a VLF detector mostly in software right?

Like:
PC audio out -> amp -> TX coil
RX coil -> preamp -> sound card line-in
then do all the filtering/phase analysis/ground balancing/etc in software.

think:
multi-frequency operation
live FFT/spectrogram visualization
phase analysis
adaptive filtering
ground balancing in software
machine learning classification
mapping/logging
experimental coil geometries


I'm thinking this because I'm pretty sure there's a bunch of hidden objects on my property placed by groups over a two decade period, I need to start surveying for what happened here and why

yes but also no
you still have to learn instrumentation electronics and that will make you more schizo and derail your project

the image is old as fuck and predates modern culture.

That doesn't answer the question.

I think it does. They weren't adding genderbender chemicals into a food and water back then. Men were men and women were women.
