Dear MacDV'ers; I've been a subscriber for a while, skimming the messages but not reading too closely. I just tried to find an archive search feature and couldn't locate it. Please advise the link if such exists, so I don't have to bother y'all if this is a repeat question. Recently I taped a ceremony in a museum, so the sound is ok, made with the Canon ZR 60 built in mic, but I'm wondering if the sound quality can be improved by a relatively simple mechanism like separating the soundtrack, importing into Garageband, and applying a filter with a tweak or two and then re-attaching to the video. Thank you. David Nuss
