Is there a way to take two mono .wav files and combine them in to a stereo .wav file? The way I imagine something like this is that the utility combining the two .wavs would have to pad the shorter of the two files out with silence. This gives you two independent streams of audio to play with. Along the same type of thinking, is there a utility that splits a stereo .wav file in to two mono .wavs? Trust me. There are a number of uses for bending the technology in this way. Martin McCormick WB5AGZ Stillwater, OK OSU Information Technology Division Network Operations Group
