There is no need whatsoever to base AAC encoder code in the reference
code to comply with the standard.

All that is needed is an encoder that complies with the stream format
specification in the standard (which is not program code).

None of the other encoders we have that comply with international
standard are based on non-free reference code (to the best of our
knowledge, of course).
