Still going through and remastering all the episodes' audio. Here's an example of what I'm doing:
After going through and scrubbing all the noise from the track and adjusting the levels, I drop the line into the timeline, match it up to the original track placement, delete the old line, move the new version into the old version's slot, then ride the levels to smooth it out even more. It's a lot of tedious work but that's what makes the sound quality soooooo much better.
This is from episode 115, so I'm almost done. Then I just need to dump the new audio into the animation timelines, adjust accordingly, and re-render.
Yeah, it's just that simple. :)
