I have a very hacky tool called speexcat, designed to cut and stitch
speex files together, and modify things like author/title tags
without the need for decoding/re-encoding. If I were to polish it up
a little (a lot), and maybe implement the ultra-wideband -> wideband
stripping, would anybody honestly use it? If so, I'd be happy to do
