Hi,

About a year ago I cobbled together a program that will read a PSN forma=
t file, compute the Hilbert transform and output the envelope back into =
a PSN format that can be viewed in WinQuake.  I have a second version th=
at also puts a cosine taper on the data in the process.  I can share it =
but someone should probably review the thing for correctness as I am not=
