I am looking for C source code for sine wave curve fitting algorithms.  Such an algorithm can be
used to compute THD/Noise in a digitized sine wave.  The fitting algorithm with adapt to phase
frequency, and amplitude and create a minimum RMS error replica of the digitzed sinewave.  The
RMS error thus indicates error in the original digitzer.
 
Thanks,
Charlie Thompson
