For what 16 bit?

BitDepth have no sense with encoded audio in frequency domain.
In the document 'Digital Audio Compression Standard (AC-3, E-AC-3) Revision B' say:
"8.2.1.1 Input Word Length
The AC-3 encoder accepts audio in the form of PCM words. The internal dynamic range of AC-3 allows input wordlengths of up to 24 bits to be useful."

Then if a input of 24 bits is appropriate for ac3 encoder also the output can be 24 bits.

Edit: and Aften accept 24 bits input without problem.
