               uridecodebin uri=file:///tmp/file2.mp3 ! audioconvert ! m. \
               uridecodebin uri=file:///tmp/file3.mp3 ! audioconvert ! m.

gst-launch-0.10 adder name=mix ! alsasink filesrc location=file1.wav ! wavparse ! audioconvert ! mix. filesrc location=file2.wav ! wavparse ! audioconvert ! mix. filesrc location=file3.wav ! wavparse ! audioconvert ! mix.

Surely isn't the best way. But, is a little start.
