I don't know if anyone has tried but is it possible to remove some of the
IBOC hash on analogue signals by using DSP audio processing?


Most stations are processing even the analog signal digitally, anyway. But
HD processing is generally done separately, to preserve more dynamic range
among other things.


Audio processing not the issue. The issue is the HD side bands screwing
up the analog reception. The noise for analog reception varies depending
on what radio you use to receive the signal.

For example I can't use the sync function on my Sony 7600G for KKGO and
KNX unless I want to hear a a low frequency buzzing in the background.
This was not an issue until they started the night time HD broadcasting
where I would want to use sync.

On the R8B and RX340 I can use sync but not side band selectable sync
unless I want to hear hiss in the background. Things will continue to
get worse the more digital mode is allowed to be used.
