Guest guest Posted December 4, 2008 Report Share Posted December 4, 2008 http://audacity.sourceforge.net/ download it there. You'll also need either the notch filter plugin or the low pass filter plugin. I think the low pass is already included. I'd be happy to edit some sound clips for you for you to test and determine whether or not they make a difference. I should be getting my low pass filtering ear plugs today or tomorrow. > > > > > > > > So I'm trying some experiements to see if I can find a path for > > us to > > > > explore. > > > > > > > > I've asked my exwife to send me some recordings of her speaking > > using > > > > offending words and sounds.

Guest guest Posted December 4, 2008 Report Share Posted December 4, 2008 http://audacity.sourceforge.net/ You'll also need the lowpass filter plugin. It may be included by default, I can't rememeber. I'll be happy to edit sound clips for you to see if you would get any relief. My low pass filter ear plugs should be here today or tomorrow. I'll keep this board posted on the results. > > > > > > > > So I'm trying some experiements to see if I can find a path for > > us to > > > > explore. > > > > > > > > I've asked my exwife to send me some recordings of her speaking > > using > > > > offending words and sounds.

Guest guest Posted December 4, 2008 Report Share Posted December 4, 2008 Hrm. Not sure why my replies are not coming through. At any rate, the software is called Audacity. just google it and download it. Try the low pass filter. Otherwise you can email me and I can edit a wav file for you to try. > > > > > > > > So I'm trying some experiements to see if I can find a path for > > us to > > > > explore. > > > > > > > > I've asked my exwife to send me some recordings of her speaking > > using > > > > offending words and sounds.
