"with BBC Radio 3, on the other hand"

Oh, and of course, the human ear, like the eye rapidly adjusts to live performances, as does the eye with changing light levels - I was able to make use of this visual trick once in a play to make people think the sun was physically moving in a sun set!

The ear adjusts quite rapidly for live performances - listening to a radio is quite an artificial experience, and you are subject to an enormous amount of compression that you are not aware of.
