This doesn't really help right now, but it looks like GStreamer will
soon be able to help you with a command like this:

gst-launch interleave name=int ! wavenc ! filesink location=/tmp/x.wav
{ filesrc location=ch2.gsm ! gsmdec ! queue ! int.sink1 } { filesrc
location=ch2.gsm ! gsmdec ! queue min-threshhold-buffers=1 ! int.sink2 }

Unfortunately the interleave plugin isn't currently fully implemented,
so this command bombs out with an error.  No one was awake on the IRC
channel to help out so hopefully they'll release a new version soon that
has the necessary bits implemented.
