Re: [IRCA] Layer Announces All-Digital AM Co-Channel Lab Test Results

I'll put their opinions in the trash can where they belong, as there is no such thing as a "digital harmonic" and - assuming they mean simply "harmonic", harmonics are not the issue with digital codecs. It's rather the artifacts of the compression that cause the odd swirls, muffling and artificial sound. None of that has anything to do with harmonics.

Chuck,

Two broadcasting engineers I know, both in CA state that they have acute hearing and to them, the digital harmonics drive them nuts, if they have to monitor IBOC audio too long. It is quite personal to them. Some people like vinyl as the audio has the "warmth" that digital audio lacks. I kind of agree with that, as I have compared both many times. An album sounds better to me, if played through a good sound system. My hearing is not that acute that affects me listening to digital. IBOC audio sounds fine to me as well as the streaming audio, but to some digital audio is not to their liking.

The all digital quality only gets it up to just below analog FM. Still in last place.but possibly equal to many streaming channels.

The question is whether it is good enough to spark more interest and then more interest sparks more receivers. Or: the FCC does something to force the issue, an unlikely possibility given their lack of desire so far.
