Default Dynamics and level compression - FM vs DAB

One thing I didn't mention on the pages was that I have also been struck
my
how my older recordings from R3 (back from circa 1980) seem to have a
wider
dynamic range despite my having to alter the recording gain at times
because of the limited SNR of domestic cassette and rtr tape.


I would agree with that. I have noticed that the envelope of recent Prom
concert recordings have that flat-topped look which the older ones don't.
I've never found the need to adjust the recording level whilst recording
from the radio as even R3 never had a wide enough dynamic range to justify
that. In any case in the past the background noise of the FM reception was
significantly greater than that from the tape. Nowadays I don't have that
problem as I get a good view of the local FM/DAB transmitter mast from my
living room window.

One advantage of FM that wasn't mentioned was the short delay. I can have
several radios, all tuned to the same station (usually R4), on at the same
time so that I can follow a programme as I move about the house. That
doesn't work with DAB or DTV. If I am recording from the radio nowadays I
usually use my Sky + and then copy from that via the optical SPDIF link to
the computer.
