[comp.sources.wanted] FFT routines

irf@kuling.UUCP (Stellan Bergman) (10/18/87)

I am looking for efficient FFT routines written either in C or FORTRAN77
(Tukey and/or Winograd algorithms) and optimized for UNIX (buffer sizes,
disk accesses, long instead of double arithmetic, etc).  96 dB (16 bits)
dynamic range is absolute minimum.

Just the subroutines themselves would be very nice but a C interface to
turn them into filters that read data from standard input and write the
corresponding FFT, IFT, ACF, etc to the standard output, would be even better. 

Thanks!
