[Cin] OT: when you try to record dolphin, but result is mostly radio interference

[Andrew Randrianasulu]

My long-time friend Julian trying to record some underwater acoustics with
resident dolphin known as Randy. Well,  long chain of equipment
(hydrophone, pream, macbook with some adapters because apple eliminated
normal separate audio line in/outs) resulted in this:

For some reason Audacity for mac refused to record  above 44.1 Khz sampling
rate, so all sound still limited to around 22 Khz frequencies.

I suggested Ubuntu studio 24.04  but while personally testing my suggestion
I run into problems, spend some time resetting win 8.1 on laptop (there was
magical command to make  Windows boot again but you need Windows install
image for it  to work ...)
