SYNOPSIS

SEISMIC UNIX NOTES SUIFFT - fft complex frequency traces to real time traces

 suiftt <stdin >sdout sign=-1					



 Required parameters:						

 	none							



 Optional parameter:						

 	sign=-1		sign in exponent of inverse fft		



 Output traces are normalized by 1/N where N is the fft size.	



 Note: sufft | suifft is not quite a no-op since the trace	

 	length will usually be longer due to fft padding.
