That would work, but it's a bit more work than I wanted to tackle.
I'm no programmer, by any stretch, and making front ends for A/D
coverters isn't entirely simple, either. A sound capture device
contains at least anti-aliasing filters, I'll have to add only
attenuators.

At the moment the Hantek 6022 is looking rather promising.

The openhantek software compiled easily on the Pi4, but it
won't run demo mode for some reason. I'd like to get a look
at that before buying hardware.

Thanks for writing,
