I believe you were talking about me.  I did manage to get some FINE looking
waveforms from my re-constituted data.  I haven't been closely following this
thread.  I'll back track a bit and catch up, then I'll give you my 2 cents.
The algorithm runs quite quickly and works strictly in the time domain.  I
can process one data point every 1.5 milliseconds on a 68000 running at 10 MHz
and can generate 4 points (including the original point) to feed to the next
stage of my process.  With a bit of tweaking, I think I can get the CPU time
down to about 1 millisecond per input data point.
