-- | Required when you set (Codec) under (AudioDescriptions)>(CodecSettings)
-- to the value AAC. The service accepts one of two mutually exclusive
-- groups of AAC settings--VBR and CBR. To select one of these modes, set
-- the value of Bitrate control mode (rateControlMode) to \"VBR\" or
-- \"CBR\". In VBR mode, you control the audio quality with the setting VBR
-- quality (vbrQuality). In CBR mode, you use the setting Bitrate
-- (bitrate). Defaults and valid values depend on the rate control mode.
