Thanks for your comments Jostein.
  Why bother the users with that kind of info? This kind
of info is probably one
 of the top 5 reasons that keeps Windows- and Mac users from trying Linux apps
 IMHO. :-) 
All right. I'll rethink the presentation. The reason was to appeal to
"power users", who won't dive in C code but can throw together a Python
or Matlab script for a DSP algorithm.
  It saves the wave file in 16 bit 44100hz sample rate.
It should at least keep
 the file's current format and at least be able to save 24 bit files. For me,
 this is the most serious point. It's important to have control over the saved
 formats. You will come far with support for 44100, 48000 and 96000 sample
 rates in 16, 24 and 32 bit. 
You're absolutely right. It's on my list of future improvements.
  One more serious (probably) thing for people that work
with samples: The
 filter section have a 0 to 3 scale for Damping in stead of a DB scale. 
Yes! Thanks for that. I also plan a logarithmic scale for the frequency
slider.
  And finally a suggestion that will make Scalpel even
more effective: Make the
 key combination SHIFT+END mark the sound from the position point to the end of
 the sound. Using the mouse for doing this is just to time consuming when
 working with many samples. The same applies for SHIFT+HOME. 
Well, END and HOME (without the SHIFT) do exactly that. I'll add a list
of keyboard shortcuts to the Help menu.
Cheers,
Pierre
