I know about variable bit rate encoding, but did wonder whether bodging something together, like that, would work. As well as the change in rates, I was thinking whether there was a beginning and end of file marker, and if you'd end up with a player stopping at the end of the first MP3. I have done similar things with MPEG videos before, joining a couple together through brute force, and it usually works if they've got the same x by y pixel sizing, but not always. -- (Currently running FC4, but testing FC5, if that's important.)
