declared in "vorbis/codec.h";

Chris@1: Chris@1:

This function puts the Vorbis decoder into or out of half-rate Chris@1: mode. In half-rate mode, the audio is decoded to only half its original Chris@1: sampling rate. Half-rate mode speeds up decoding at the expense of Chris@1: decoded audio quality.
