Perhaps this is better asked in a audio newsgroup?
I don't think so as the header isn't part of the audio. If you're in an experimenting mood, try ripping several tracks as a single wav and encode to a single mp3; then rip the same tracks as individual wav's and encode to individual mp3's. My guess is that the sum of the individual mp3's will add up to more than the single mp3 due to the headers. Todd
