The audio carriers are at different frequency offset from the main

there may even be some sources where you get no audio. South America has a
PAL/NTSC mix, but the PAL is 60hz so it sort of works no matter which
receiver you use. (this probably has something to do with why PAL is more
popular than SECAM) It was interesting to find out the the same company
now owns all three companies that developed the three standards.

I was surprised at the large number of different
PAL standards in the link you gave for that.
I'm surprised myself and didn't read the English Wiki.
Btw. all the times I've seen television from former Yugoslavia
countries, at least gypsy television, audio was distorted.
When somebody from a German night show made a joke about Turkish
television, they add distortion to the sound.
I wonder if the engineers in those countries are idiots, or if there
should be a technically reason for the distorted audio signals.
