[Speex-dev] What establishes "average" bitrate in Variable Bitrate (VBR) Mode?

[Randy Yates]

If I specify VBR mode via

  speex_encoder_ctl(pSpeexEncoder, SPEEX_SET_VBR, &isTrue);

then what establishes the "average" bitrate? Is it the normal bitrate
command,

  speex_encoder_ctl(pSpeexEncoder, SPEEX_SET_BITRATE, &vbrBitrate);

or the associated quality command?
