Sorry, this is a feature that is still missing in all PDA's to this date. The only "built in" option for audio capture is the microphone. Which, if you get the right recording program and tweak your mic settings a little, can produce pretty good recordings. However, if you're looking to do some serious audio work you may want to check out this link. http://www.core-sound.com/HighResRec...html#EXPANSION I haven't tried this yet but it is on my Christmas wish list. Hope this helps.
