As seems to happen with some regularity, there are rumors once again about Apple investigating high-quality music for iTunes. Kirk McElhearn explains why this is probably not the case:
[The new Apple TV] only handles audio at 16 bits and up to 48 KHz. So if Apple were planning to start dealing in high-resolution audio (generally considered to have a bit depth of 24 bits, and sample rates higher than 48 KHz), you’d have thought this device would be able to handle such audio.
Most people couldn’t care less about high-resolution music. For the most part, it’s a marketing ploy, and hardly anyone can tell the difference between CDs and good-quality compressed audio.
