| Chris@1 | 20 <p>This function puts the Vorbis decoder into or out of half-rate |
| Chris@1 | 21 mode. In half-rate mode, the audio is decoded to only half its original |
| Chris@1 | 22 sampling rate. Half-rate mode speeds up decoding at the expense of |
| Chris@1 | 23 decoded audio quality.</p> |
