I'm perfectly aware of how to use the --nogap switch and my test files
are available for anyone to examine. I respectfully suggest that you do
so before accusing me of incompetence.

I don't like the --nogap hack either, but it's the only way to squeeze
gaplessness from the usual sort of idiot player that can't make file
transitions without a humongous delay. Strip, concatenate, copy.

Concatenated --nogap files *stripped of tags* sound seamless. Tagged
files, --nogap or no, played separately don't...at least not always.
This is where I run aground since, while I know a great deal about mp3
stream structure, I freely admit that I don't know jack about the actual
encoding and decoding.

At any rate, so far as I'm concerned, this discussion is over. From
making a simple observation I've allowed myself, like a damned fool, to
spend hours justifying my original claim. Well, I'm sick of it. If
anyone else cares (and, frankly, I don't anymore), he's free to take the
baton.
