Subject:Need a script to subtract one .wav from another

Maybe somebody smarter than me can help me out with this...
All I need is a script that does the following:

1. Open a first file whose name and path are supplied by a script argument
2. Open a second file whose name and path are supplied by a script argument
3. Invert/Flip the entire first file
4. Mix the entire second file with the entire (inverted/flipped) first file, similar to using the menu item Edit=>Paste Special=>Mix.
5. Save the resultant mix to a third file whose name and path are supplied by a script argument
6. Exit SoundForge

If somebody could supply me with a sample script that would perform the above actions I would be very grateful... I've been staring at this thing for a while now and I'm just running out of time.
**Edit** I'm looking to do this in JScript BTW.

Here's a basic script. It could use some better error handling, but it illustrates the basic steps.

Script : "Mix Inverted.cs"

using System;

using System.IO;

using System.Windows.Forms;

using SoundForge;



public class EntryPoint {

public void Begin(IScriptableApp app) {



   string strFile1   = GETARG("file1", "");

   string strFile2   = GETARG("file2", "");

   string strOutFile = GETARG("outfile", "");



   if ("" == strFile1 || "" == strFile2 || "" == strOutFile)

   {

      MessageBox.Show("useage\nfile1=path\\filename&file2=path\\filename&outfile=path\\filename", "invald arguments");

      return;

   }



   ISfFileHost fhOne = app.OpenFile(strFile1, true, true);

   if (null == fhOne)

      return;



   ISfFileHost fhTwo = app.OpenFile(strFile2, true, true);

   if (null == fhTwo)

   {

      fhOne.Close(CloseOptions.DiscardChanges);

      return;

   } 



   ISfFileHost fhOut = app.NewFile(fhOne.DataFormat, false);



   fhOut.ReplaceAudio(new SfAudioSelection(0,0), fhOne, new SfAudioSelection(fhOne));

   fhOut.DoEffect("Invert/Flip", 0, new SfAudioSelection(fhOut), EffectOptions.EffectOnly);

   fhOut.WaitForDoneOrCancel();



   fhOut.MixAudio(new SfAudioSelection(fhOut), 1.0, 1.0, fhTwo, new SfAudioSelection(fhTwo));

   fhOut.WaitForDoneOrCancel();



   fhOut.SaveAs(strOutFile, fhOne.SaveFormat.Guid, "Default Template", RenderOptions.RenderOnly);

   fhOut.WaitForDoneOrCancel();

   

   fhOne.Close(CloseOptions.DiscardChanges);

   fhTwo.Close(CloseOptions.DiscardChanges);

   fhOut.Close(CloseOptions.DiscardChanges);

  

   // Close Sound Forge.

   System.Diagnostics.Process curr = System.Diagnostics.Process.GetCurrentProcess();

   curr.CloseMainWindow();

}



public void FromSoundForge(IScriptableApp app) {

   ForgeApp = app; //execution begins here

   app.SetStatusText(String.Format("Script '{0}' is running.", Script.Name));

   Begin(app);

   app.SetStatusText(String.Format("Script '{0}' is done.", Script.Name));

}

public static IScriptableApp ForgeApp = null;

public static void DPF(string sz) { ForgeApp.OutputText(sz); }

public static void DPF(string fmt, object o) { ForgeApp.OutputText(String.Format(fmt,o)); }

public static void DPF(string fmt, object o, object o2) { ForgeApp.OutputText(String.Format(fmt,o,o2)); }

public static void DPF(string fmt, object o, object o2, object o3) { ForgeApp.OutputText(String.Format(fmt,o,o2,o3)); }

public static string GETARG(string k, string d) { string val = Script.Args.ValueOf(k); if (val == null || val.Length == 0) val = d; return val; }

public static int    GETARG(string k, int d) { string s = Script.Args.ValueOf(k); if (s == null || s.Length == 0) return d; else return Script.Args.AsInt(k); }

public static bool   GETARG(string k, bool d) { string s = Script.Args.ValueOf(k); if (s == null || s.Length == 0) return d; else return Script.Args.AsBool(k); }

} //EntryPoint

Thanks for that! It does exactly what I need it to.
