sound editor or viewer, or application for displaying graphs (probably in a scroll view)

[Dan Hitt]

Is there a GNUstep application which displays waveforms?

These could be waveforms from sound files, or other sources.

What about one that draws graphs (which is of course related,
especially if it can handle sampled data with hundreds
of thousands of samples, i suppose in some kind of scroll view)?

(I am aware of many fine applications such as Audacity, but
wondering if there's a specifically GNUstep one, which need not
be very full featured.)

I looked at
    http://www.nongnu.org/gap/
and saw OresmeKit (for drawing graphs) --- but it's not released yet,
and when it is i presume that it won't be an app but a
framework to be used in creating apps.

I also googled around, and found lists of sound editors,
such as
    http://appindex.freecode.com/search?page=1&q=sound+editor
but searching for sound+gnustep just gives one result (which is
not for waveform display):
    http://appindex.freecode.com/search?page=1&q=sound+gnustep

Thanks in advance for any reference to any app, or for suggestions
on how i could do a better search.
