> Synthesize a signal from a track of linear prediction coefficients.

## Documentation

> 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.

> 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 lpc_filter along with the LP coefficients for that frame. This function writes directly into the signal for the values between start and end;

Parameters:
  sig - the waveform to be synthesized
  lpc - a track of time positioned LP coefficients
  res - the input residual waveform
