I understand that michael wants RD before heuristics, but what exactly are
you doing that makes this 1000x slower than faac, libvorbis, lame, and
3000x slower than ffac3?
Is this the first RDOed lossy audio codec anyone has ever written?
Are you testing the tensor product of all possible choices while others do
gradient descent? Is it just that unoptimized?
