Gwave with GnuCap

Hello there,

I know its kinda off, but I don't have anywhere else to ask: Is it possible
to use gwave with gnucap? I've tried here, but gwave wouldn't display
correctly the waveforms. For now, I'm using gnuplot, but it is not
convenient.

With gwave, I get distorted waveforms that have nothing to do with my wave
files.

Versions:

gnucap-0.35
gwave-20090213

Thanks in advance,

Ivan
