<p>Plays an audio stream at a different speed (by resampling the audio).</p>
<p>Do not use this element. Either use the 'pitch' element, or do a seek with
a non-1.0 rate parameter, this will have the same effect as using the speed
element (but relies on the decoder/demuxer to handle this correctly, also
requires a fairly up-to-date gst-plugins-base, as of February 2007).</p>
