You can use a tool like Spectrafoo to verify this. There is an example of it's bit meter in the upper right corner of the picture here:
There are no doubt other analyzers with such a display but that is the one we use here.

I hope someone here can help me with this technical question. I have some doubts about a file being digitized at true 24-bit. The file says 24-bit but Iím not sure how to verify it. Is there a way of verifying a file to see if itís truly 24-bit and not 16-bit conversion in a 24-bit file?
