    All new LSP->freq envelope curve computation code.
    It turns out that LSP->LPC using the impulse response algorithm is
    *very* sensitive to noise, and doubles really are necessary.
    Unfortunate, that.
    Reimplmented the code with a direct LSP->curve computation, skipping
    the LPC intermediary step.  This also eliminates any need for the LPC
    or iFFT code in decode/synthesis.
