>Missing doc/general update

I will wait for a few days to see if there will be additional comments on the patch and then add doc/general update and resend patchset.

I have a question regarding this.
I saw that for AC-3 encoder IX is used.
I guess that "I" stands for integer (I didn't find documentation regarding this).
Is it enough to add the same for decoder (since it is just X now), or I need to add entirely new entry for fixed point AC3.
