By the way, if you've incorporated Moth3r's transfer with other audio-tracks, the command line changes a tiny bit: Instead of just putting the desired audio level at the end (31 in Moth3r's example), you'll have to have the number of the audio track first (0 being the first one), followed by a slash and the level (so, if the second audio track should be changed to 31 it'll be "1/31").
