cannam@86 22 The ovectl_ratemanage_arg structure is used with <a
cannam@86 23 href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> and the OV_ECTL_RATEMANAGE_GET,
cannam@86 24 OV_ECTL_RATEMANAGE_SET, OV_ECTL_RATEMANAGE_AVG,
cannam@86 25 OV_ECTL_RATEMANAGE_HARD calls in order to query and modify specifics
cannam@86 26 of the encoder's bitrate management configuration. Note that this is
cannam@86 27 a deprecated interface; please use vorbis_encode_ctl() with the <a
cannam@86 28 href="ovectl_ratemanage2_arg.html">ovectl_ratemanage2_arg</a> struct
cannam@86 29 and OV_ECTL_RATEMANAGE2_GET and OV_ECTL_RATEMANAGE2_SET calls in new
cannam@86 30 code.

cannam@86 73 <dd>Regulates the relative centering of the average and hard windows; in libvorbis 1.0 and 1.0.1, the hard window regulation overlapped but followed the average window regulation. In libvorbis 1.1 a bit-reservoir interface replaces the old windowing interface; the older windowing interface is simulated and this field has no effect.</dd>
