[gst-devel] adder and float

[Jonathan Giannuzzi]

I simply tried with gstreamer/examples/mixer/mixer.c
With two or more mp3's, it works OK.
Haven't done further testing since I gotta go.

I think modifying mixer.c to not use arbitrary decoders (maybe spider) and use 
audiosink from gconf would make it a good testcase for adder and volenv.
