How to output to standard output?

Gstreamer should decode files and output the data to the standard output so it can be further processed by another program. I somehow don't know which sink to add at the end. The following is my command:

gst-launch filesrc location="$(FILE)" ! decodebin ! audioconvert ! audio/x-raw-int,rate=44100,channels=2,width=16,depth=16,endianness=1234,signed=true

But where do I have to direct this to?
