[LAD] web expert advice wanted

[Fons Adriaensen]

Hello all,

I need some advice from a web protocols expert...

I want to record the _audio_ part of 

<https://www.skylinewebcams.com/en/webcam/ellada/crete/rethymno/karavostasi-underwater-cam.html>

during a long time without wasting bandwidth on the video part,
and avoiding being 'timed out' or blocked by 'please whitelist
our ads' popups.

Anyone has an idea of how to do this ?

TIA,
