Important question about subs

[Shannon]

Here is an example of what I'm talking about. Let's use the new BASE program that has not yet been released. I am using a Linux system. md5sum is in coreutils, so it's easily accessible for me.

Actual size in bites is rarely the same. It can be shown differently on different operating systems, and on different file managers.

I used to use byte padding to fill the last sector's worth of data in each mp3 file with enough data to complete the sector in which it was being stored on the disk, but I do not do that now because it was raising questions like these. I also stopped using that DAW to encode my files for mp3. But in the DAW, the difference is just a checkbox that I unchecked to stop padding bytes at the end of the file.
