theres a widget in /extensions/gui/ix/toxy/sp.wid in CVS that does this, with flexible scaling, ranges, log-linear, colors etc. ive found by tweaking the settings as input is playing, you can usually get a pretty good image. can't edit the spectrogram though. for that, try something like the latest version of wavelab, or soundprobe.. and possibly tapestrea
