OK, I see the problem - you're using the downloadable version, but I uploaded the wrong file. I've now updated the file so here it is again:
download/file.php?id=20305

If you want to print a list of frequencies, find the line:
Code: Select all
;(format t "Frequency ~a~%" hz)

and remove the semicolon from the start of the line (and use NotePad++ )

Note also that if there are a lot of harmonics and a lot of gain per harmonic, there may be numerical overflow and the output will be corrupt.
