I believe no floats are involved in the DTS encoder code
(though I guess in the decoder, so that might break it).
For nellymoser and ra144 I am not sure that any rounding
errors can actually cause failures/different output.
For ra144 at least the decoder is integer-only.
But even so, running this through FATE once would be an
easy way to get the right PSNR limit values for the other
Of course that only helps if I can actually use our standard
audio reference there, too. The wma test use only the "luckynight"
There is also a bit the problem that when using enc_dec_pcm
we'll probably never notice when due to decoder improvements
that CMP_TARGET value should be made more strict.
