This is the wonderfully intuitive tool I've been using to take .wav files and weave them into a voice pack. Auto-generates a readme file, has four team support, and can boost or nerf the volume of your pack (ignore what it says about volume levels above 1.0 being irrelevant, I've made most of my meaningful volume shifts in the 10-30 range!) If you'd like tips on good free programs for editing audio or extracting said audio from voice files posted on youtube, see my tutorial on the "tutorials" tab of this mod. TROUBLESHOOTING NOTE: You may need to make a clone of your UT2004 directory at the location where the packager looks for files. It consults all kinds of files from UT2k4, so might as well just move your backup folder of UT2004 to the location where it looks, since it doesn't alter the files.
