-/**
- * SECTION:element-lamemp3enc
- * @see_also: lame, mad, vorbisenc
- *
- * This element encodes raw integer audio into an MPEG-1 layer 3 (MP3) stream.
- * Note that <ulink url="http://en.wikipedia.org/wiki/MP3">MP3</ulink> is not
- * a free format, there are licensing and patent issues to take into
- * consideration. See <ulink url="http://www.vorbis.com/">Ogg/Vorbis</ulink>
- * for a royalty free (and often higher quality) alternative.
- *
- * <refsect2>
- * <title>Output sample rate</title>
- * If no fixed output sample rate is negotiated on the element's src pad,
- * the element will choose an optimal sample rate to resample to internally.
- * For example, a 16-bit 44.1 KHz mono audio stream encoded at 48 kbit will
- * get resampled to 32 KHz. Use filter caps on the src pad to force a
- * particular sample rate.
