Indeed. And so far as I know, the BBC still use NICAM for the
distribution for FM. Hence it is digital with a 32k sample rate and
less than 16 bits per sample. So nominally 'worse than Audio CD'. Yet
can sound fine. People ceased being able to hear an all-analogue FM
chain decades ago.

Maybe fewer than 16 bits but it's almost a floating point encoding so
gives better resolution at low levels than you might think.

Yes, this may help people who've not checked it out.
