I thought it was the other way around: that WAV files don't have headers
and are just 'raw" audio, and that MP3 files did have headers. I know
"catting" two MP3s together "works" but leaves a little "blip".

I was thinking that dd might be the way to go, like how people use it to
bust a backup into CD-R sized pieces.
