Will 24 Bit, versus 16 Bit affect sync over a period of time since the camera's audio records at 16 Bit? Not at all...
....once again though, higher is better...in this case, more bits = more information captured/less information loss or tossed
edit...for those who are following this thread....
Bit Depth refers to the number of bits you have to capture audio. The easiest way to envision this is as a series of levels, that audio energy can be sliced at any given moment in time. With 16 bit audio, there are 65, 536 possible levels. With every bit of greater resolution, the number of levels double. By the time we get to 24 bit, we actually have 16,777,216 levels.
Sample rate is the number of times your audio is measured (sampled) per second. So what is the 96khz sample rate? It's 96,000 slices of audio sampled each second.
Bit Rate, or how much data per second is required to transmit the file, which can then be translated into how big the file is. A CD is 16bit, 44.1 so that is 44,100 slices, each having 65,536 levels. The R4 can record 96,000 slices a second at nearly 17 million levels for every slice. The Bit Rate is usually expressed in Mbit/sec.
48 mHz/16 bit = 1.35 Mbit/sec
96 mHz/24 bit = 4.39 Mbit/sec

). The live band was pumping a very HOT signal...the R4 just prrrrd away.... :-)
