My application is a mode 1300 vocoder only, so I thought I would just
simplify the library. Woof... You'd think the same C compiler would produce
the same output given two identical functions...
Anyway, I have it down to to just two bit-errors now in the hts1.raw
encoding. I can't figure out why they are different, but one of the errors
is in the codebook index (off by one) of one of the middle frequency
formants. I think the other is a voicing bit error.
