Transmitting material deliberately tweaked for a poor listening

have a compressor built in if that's the sound you want rather than
inflicting it on all listeners. Indeed part of the spec of DAB included
such a device although I've not known it be implemented.
It is implemented on my Arcam DAB receiver. Problem is that it is in
my home, and I don't need to use it there.
Right. How well does it work, out of interest?
Quite well, I would say. I tried the radio in the laundry room to see
how it would cope with the noise of the tumble drier, and it made a
pretty good job of staying audible.
My car radio will alter the level taking into account background noise,
though. And eq the speakers using the same microphone as sensor - if you
want. Haven't tried either yet as the mic isn't supplied as standard.
It wouldn't work if it were fitted. It would equalise to where the mic
is, not where you are, and they will have vastly different frequency
response errors, particularly in a car.
The idea is you put the mic where your head is when doing the auto eq then
save the settings. But you aren't then forced to use them - it will store
several different settings which may be manually set and recalled. But
like all such things I've settled on flat with a small amount of LF lift
to counteract tyre rumble etc.
Ah - ok. I thought maybe it was some fixed position thing you clipped
on a sun visor, or something.
