[BC] QUESTION FOR THE "MIND" MASSES

[Robert Meuser]

Bob:

My experience is that the difference is too small to matter. Surprisingly this 
includes most AM HD. You and Frank have done too good of a job making the 
processing transparent that it is hard to tell the difference.  I am beginning 
to think more in the direction Frank wants to go. 5.1 would jump off the dial 
better. At the end of the day multicast and other features will make or break 
IBOC - I am not and never had heard an audio quality issue. In the past I have 
heard some really horrendous audio on AM. Frequency response is trumped by 
cascaded codecs.
