<h1>vorbis_synthesis_halfrate</h1>
<p><i>declared in "vorbis/codec.h";</i></p>
<p>This function puts the Vorbis decoder into or out of half-rate
mode. In half-rate mode, the audio is decoded to only half its original
sampling rate. Half-rate mode speeds up decoding at the expense of
decoded audio quality.</p>
