Comment (by Kamedo2):

 Replying to [comment:351 klaussfreire]:
 > I'm not sure whether to fix or scrap fast and faac. Fast would be nice
 to rewrite using twoloop with quick and dirty parameters (far few
 iterations for instance), faac not sure how it compares against the
 others.

 Faac on v9 is extremely bad. I don't think we will need many -aac_coder
 variant in the final version. Overwhelming majority will use the default
 setting.
