This configuration can be used only with stereo input audio data. 129: MPEG-2 AAC Low Complexity. 132: MPEG-2 AAC Low Complexity with Spectral Band Replication (HE-AAC).

• bitrate_mode

  allowed_bitrate_modes()

  Default value: 0
  Bitrate Mode. See: http://wiki.hydrogenaud.io/index.php?title=Fraunhofer_FDK_AAC#Bitrate_Modes 0 - Constant Bitrate (default). 1-5 - Variable Bitrate

• bitrate

  pos_integer() | nil

  Default value: nil
  Bitrate in bits/s for CBR. If set to nil (default value), the bitrate will be estimated based on the number of channels and sample rate. See: https://trac.ffmpeg.org/wiki/Encode/AAC#fdk_cbr Note that for VBR this parameter is ignored.
