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> <table border=0 color=black cellspacing=0 cellpadding=7> <tr bgcolor=#cccccc> <td> <pre><b> extern int vorbis_synthesis_halfrate(vorbis_info *v,int flag); </b></pre> </td> </tr> </table> <h3>Parameters</h3> <dl> <dt><i>v</i></dt> <dd>The <a href="vorbis_info.html">vorbis_info</a> structure for the decoder instance.</dd> <dt><i>flag</i></dt> <dd>Whether half-rate mode is to be turned on or off.
