Howdy. After many years of saying that I’ll eventually get to preserving LD audio, I finally got around to starting it. I have a D704 and have tested DTS and PCM bit-perfect preservation (AC-3 pending), and I have three questions:

What is the best way to edit out the dead audio from a file? I would think a python script or something to read the data and remove the dead audio would be the best, but I haven’t found a tool that’s perfect. DTSParser stops at the side break of a DTS recording, and with PCM I don’t want to hear a pop.
I looked before asking this - how are people syncing up the audio with the video? I see posts about 100+ edits on some projects and I wonder how the edits are done without removing bits of the audio which we’re trying to preserve in the first place. Does the audio waver in parts? Have people stretched/compressed the time of the audio to sync with the video?
What tool are people using to test the synchronization of the audio and video? AviSynth?

Thanks
