Hi,

yes ORC is the successor and its much better. There are already several
examples in GStreamer of how to use ORC for audio.
Here is some documentation how ORC is integrated in gstreamer:
http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/docs/design/design-orc-integration.txt

And here are two plugins that use it:
http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/gst/audioconvert
http://cgit.freedesktop.org/gstreamer/gst-plugins-base/tree/gst/volume
