I agree with Scott about the “difference in quality” issue. Probably the only way people would notice a difference in audio quality would be to play the files side-by-side. Even then it would be difficult because of the relatively low quality of playback speakers/headphones. I’ve tried it with groups of people. And people really only notice bad audio when it is actually bad, not when it is just not as good as pristine.
And there definitely are batch converters (free and $). But getting some audio people to believe this may be difficult. They can be a stubborn lot, especially if they come from the days of tape recording when moving analog audio around really could audibly degrade it.
