New LSP code committed
So, it turns out (and another implementation actually explicitly mentions it)
that LSP->LPC computation using the FIR algorithm is very sensitive to noise
(iterative algorithm) and really really requires doubles [we're not kidding].
This was complicating things for folks pursuing fixed point implementations,
and also was a potential source for bugs if FP optimizations got out of hand.
This
