- *
- * <refsect2>
- * <para>
- * This element lets you output sound using the WaveForm API.
- * </para>
- * <para>
- * Note that you should almost always use generic audio conversion elements
- * like audioconvert and audioresample in front of an audiosink to make sure
- * your pipeline works under all circumstances (those conversion elements will
- * act in passthrough-mode if no conversion is necessary).
- * </para>
- * <title>Example pipelines</title>
- * <para>
- * <programlisting>
- * gst-launch-0.10 -v audiotestsrc ! audioconvert ! volume volume=0.1 ! waveformsink
- * </programlisting>
- * will output a sine wave (continuous beep sound) to your sound card (with
- * a very low volume as precaution).
- * </para>
- * <para>
- * <programlisting>
- * gst-launch-0.10 -v filesrc location=music.ogg ! decodebin ! audioconvert ! audioresample ! waveformsink
- * </programlisting>
- * will play an Ogg/Vorbis audio file and output it.
