Below is a quote from your page at

'And listening to Radio 3 or 4 using the FM tuner demonstrates how
much nicer these can sound via FM than via DAB.' I quite agree but
would you say this is a result of the low bit rate the bbc uses or is
an indication of the inherent superiority of analogue vs digital
sound reproduction?

Alas I can't give a simple yes/no answer to that question because
there are a number of differences between FM and DAB in practice.
Couple of examples:

FM tends to add some low order distortion, and also intermod,
particularly for stereo. Caused by the limited bandwidth, etc.

BBC FM has *level* compression applied in a different way to DAB. So
the dynamics are likely to be different. My impression is that this
tends to make the FM sound 'warmer' as it acts a bit like a 'sustain'
pedel.


I wonder why human ears prefer the sound of a bit of 'sustain'? I
certainly do.

Have a mate who constantly goes on about how much better FM is than
digital.

So set up a test for him. Three tuners all on R3 - one FM, one DAB, one
Freeview. Levels carefully balanced. A long silent pause when switching
between them - so the delay on digital didn't give the game away.

He failed miserably to distinguish which was which. ;-)



He should get his hearing checked then!....
