I would like to use gstreamer to save an arbitrary clip from one audio file to a new file. For example, a segment from 1 minute to 2 minutes in the original. How do I do it?

    You need gnonlin. See http://www.jonobacon.org/2006/12/27/using-gnonlin-with-gstreamer-and-python/

    You won’t need a gnlcomposition because you only want one segment. Use a gnlfilesource with its start and duration set to 0, 1 minute, and media-start and media-duration set to 1 minute, 1 minute. All times and durations are in nanoseconds.

    Take 5 seconds from source.mp3 starting at 10 seconds, write to destination.ogg:

    gst-launch-0.10 gnlfilesource location=$PWD/source.mp3 \
start=0 duration=5000000000 media-start=10000000000 media-duration=5000000000 ! \
audioconvert ! vorbisenc ! oggmux ! filesink location=destination.ogg
