    I just picked up The Band's Greatest Hits and it is 24 bit digitally re-mastered. What are CD's normally mastered in? Is this a good thing?

    CDs are normally mastered to 16 bits, so the added 8 bits allegedly gives 50% more "clarity."

    Someone is going to explain this better soon, I hope, for your sake.

    All CDs have 16 bits of detail.

    The extra 8 bits of detail in a 24-bit master are dithered into the 16th bit on the CD. Dithering extends the dynamic range, although it is only audible below the noise floor. Noise-shaping is a frequency-based weighting on the dithering which moves noise to higher frequencies where it is much more difficult to hear the noise at low (-96 dB) levels.

    24-bit mastering is a good idea. Whether a particular CD made from a 24-bit master sounds good is a different matter.
