[speex-dev] narrowband embedded in wideband

[Matthias Granberry]

It looks like I'll need to go further into the guts of speex to do
this.  I do, however, see some lines in nb_celp.c/nb_decode() that
look interesting.  I guess I'll play with it.  I doubt that it will be
terribly clean, though.

 Jean-Marc: Take a look at line 1195 in nb_celp.c (CVS).  It reads
 "speex_warning ("More than to wideband layers found: corrupted
 stream?");" when it should be "More than two wideband layers..."
