Log message:
Import gst-plugins1-soundtouch-1.6.1 as audio/gst-plugins1-soundtouch.

GStreamer is a library that allows the construction of graphs of
media-handling components, ranging from simple Ogg/Vorbis playback to
complex audio (mixing) and video (non-linear editing) processing.

Applications can take advantage of advances in codec and filter technology
transparently.  Developers can add new codecs and filters by writing a
simple plugin with a clean, generic interface.

GStreamer is released under the LGPL.

This package is part of the 'bad' plugins for GStreamer.  It provides the
soundtouch plugin, which allows detecting BPM and changing pitch
of audio files.
