From Tom Fine: "...The only cases I know of where something is released for
download-only with no ability to buy a CD (or LP or 45-single) because none
were printed, would be very-indie self-made albums and special one-off
singles, like for instance the famous Bed Intruder song that was a YouTube
and then iTunes sensation. "
Apple requires that their software be used to upload directly from an audio
CD. This gives them the capability of releasing bit-accurate audio files but
also restricts them to the technical limitations of the 44.1x16 bit format.
Jim Johnson, the inventor of AAC at Bell Labs, says that there definitely
should be less degradation when encoding from higher resolution sources. He
thinks of his process as very smart dithering. People tend to think of audio
degradation as being a linear process whereas it isn't at all. Jim says that
an AAC file having a 48k. sample rate that was encoded from a 24 bit source
could potentially sound better than "CD quality" in spite of the much lower
bit rate. The main thing to understand is that this lossy-coded audio is
very fragile and should never be subjected to any additional signal
