See, the problem is that the decoder should know its own latency and the
encoder knows its own and so can store that information in the XING header.
MP3 will splice gaplessly and with the editing software I have, I can edit
down to the sample and have done it visually with sample-perfect results.
What's intriguing is that this has any issues at all.

So, I'm not sure who is the one that didn't think it through enough-- the
designers or myself by just being unaware of something that becomes obvious
when getting into the nitty-gritty.
