     thanks. If the other program you are referring to is Spectran, >

Well, not particularly...  I do have a little trouble with Spectran but it
runs OK It always gives the error message that the soundcard is in use by
another application but, if you ignore that, it works until you want to
change something. That is on the shack PC with a Creative Labs card. I have
a lot of trouble with my laptop (P100 and ESS sound chip) which only seems
to like Spectrogram and Argo, Argo runs fast enough to give good resolution,
whereas Spectrogram goes too slowly.

The new version of NIAGARA will run on a P100 and ESS sound chip.
It needs DOS though, not Windoze.
Has color now, and can do spectral magnification.
Why not try it?  You might like it :-)

Just invoke with a command line parameter of "SB" and it will use your
ESS chip.  You will need the usual "BLASTER= environment statement.
