A slight reduction in Data after moving it from ExFAT

[levmc]

15,977,545,728 bytes (15.98 GB on disk) (This is what it says on ExFAT partition info)

15,965,361,439 bytes (16.1 GB on disk) (This is what it says for my folder that I transferred the data to, in the internal drive of my iMac).

Why is there a difference?
15,977... reduced to 15,965... bytes.
These are music files (AIFF), would there be loss of sound quality?

Or could the computer just be reading the same quantity differently because it's on different formats?

Yes...there are different methods to calculate space, and possibly there could be metadata differences between formats. Maddening, but not uncommon. I don't think the files themselves should be affected...so no quality difference. If the file were different/missing anything, it would likely be corrupted (unusable).
