Bit Depth

I know Bit Depth (sample size) has been requested here before, but is there any particular reason why Bit Depth (e.g. 8-bit, 16-bit, 24-bit etc.) has not been added to MP3Tag as an Information field?

Because MP3 is basically Bitless...

For in depth explanation, read this:

Yes, but MP3Tag doesn't just support the mp3 file format.

Indeed...I didn`t thought about that...
