I'd suggest you take a peek in the Let's Play Nofriendo Entertainment System subforum's Tech Support Fort. They've got links to some writeups that may help you. And you could always just ask in there.

If you're using AviSynth or basically any other NLE, you're only saving a list of edits until you do the final rendering. There will be no loss of quality.

If you want to render intermediate files, there's lossless codecs available (don't render uncompressed, it's just a waste of space). Lagarith is one such lossless codec. HD material will still be huge, but at least manageable. Not something you'd want to upload to Youtube, though. You can render to Lagarith from AviSynth by using VirtualDub.

As for the audio side of things, just keep things raw WAV until the final render, the audio size will generally be dwarfed by the video size anyway.

Playing an AviSynth script to check for audio sync is a recipe for disaster. Though if all you're doing is adding some frames, it might work.
You can get VirtualDub to show you the audio track of an AVS, so if you're just checking for peaks matching certain frames, do that.

Otherwise, just render a very low quality video.

Audacity project files are a great way to avoid quality degradation, so no worries there.
