Audio jack

I investigated this intending to write a TDR (Time Domain Reflectometer). However some idiot decided at some point that, on phones, the microphone input is on the outer sheath of the jack. Look it up – Phone connector. So, providing you can make up a suitable jack it should work. However I do have an Oscilloscope app as part of my AudioTools. There are Windows and MacOS versions and it is free open source software.
