<BLOCKQUOTE>Synthesize a signal from a track of linear prediction coefficients.
This function takes a set of LP frames and a residual and produces a
synthesized signal.
<P>For each frame, the function picks an end point, which is half-way
between the current frame's time position and the next frame's. A
start point is defined as being the previous frame's end. Using these
two values, a portion of residual is extracted and passed to
<!1><A HREF="lpc_filter.html">lpc_filter</A> along with the LP coefficients for that frame. This
function writes directly into the signal for the values between start
and end;
