Interesting article. I think the problem may be moot when stations find out that the only way they are going to make any money from their digital HD stream is to have alternative programming on the digital side.
People are not going to buy new FM radios to receive the same program stream in digital format. The audible improvement, if any, is too small to warrant purchase of a new receiver. Although the program material could be broadcast with wider dynamic range in the digital form, the satellite broadcasters have found they have to dynamically compress because most listening occurs in cars. Road noise and wind noise limit how low you can go on level in the auto environment before the program is under the audio noise. The only other option would be ruptured ear drums on the up side. So the satellite guys compress the dynamic range as much as the analog FM guys do. XM now has a channel called XM Pops which transmits light classical music in surround sound. There is at least one home receiver designed to demodulate this channel in its fullest glory. It sounds quite good on a normal stereo receiver too and I think the dynamic range is greater than average as I catch myself reaching for the volume control during soft passages. Once the need for alternative programming is realized, the NAB will lobby the FCC to drop the requirement to carry the same program material on the digital and analog services. Eventually they will probably drop the analog program ala what is about to happen with TV.
