I guess i never put much thought into the tech besides bigger numbers are better. Here's something I found in a search...
"The amplitude of each sample is a numeric value that is represented by a certain number of bits. The more bits that are used to represent the amplitude, the greater the dynamic range that can be represented, with each bit providing a gain of approximately 6 dB. The dynamic range of 16 bit digital audio is therefore approximately 96 dB, whereas the dynamic range of 24 bit digital audio is 144 dB. 8 bit digital audio has a dynamic range of approximately 48 dB. The amount of data created by digital audio is quite large. 16 bits per sample at 44.1kHz creates 705600 bits per second."
The number of bits recorded per Khz puts in perspective. It's over a million at 24 bits. Sure, I'd love to hold out for 24/96 but that could be years.
These are just the stereo mixes that were announced. It's listed on Amazon.
