vorbis_synthesis_halfrate

declared in "vorbis/codec.h";

cannam@86: cannam@86:

This function puts the Vorbis decoder into or out of half-rate cannam@86: mode. In half-rate mode, the audio is decoded to only half its original cannam@86: sampling rate. Half-rate mode speeds up decoding at the expense of cannam@86: decoded audio quality.
