Audio outside the box

I am slogging through many, many DV files which require a second audio track (boom mike) to be synched to the picture. It helps to have both the picture (clapboard) and waveform from the camera audio to stay accurate, but I wonder if there's a product out there that would save me these many hours. Anyone know of software that will vertically align the matching waveforms of two audio tracks on adjacent timeline tracks? I'm not talking about timecode because the boom mike is DAT converted to a wav file--no matching timecode.

I'm unawares of anything that could be used to auto-match the files. You're going about it in the best way I'm aware of, outside of stamping T/C on the DAT tape or having genlock lash them up together.

Since you can't sync to the camera timecode in this case, your best bet is clapboards at the beginning AND end of each take. It's then a case of stretch (or squeeze) and align, until your beginning and end markers are lined up. Shoot for the zero crossing of the waveforms, makes it easier than lining up peaks.

In my case all my shoots are music, so I use snare drum hits instead of the clapboard.
