StereoMode::Enum.

Enumerator
None	None/LR mode is chosen by default.
LR	If MPEG/AAC encoder is used with LR mode the encoding will be done using normal independent coding of left and right channels.
MidSide	If AAC encoder is used with mode MidSide the encoding will be done using Mid/Side coding technique. If MPEG Audio encoder is used with this mode: Layers 1 and 2: the encoding will be done using normal independent coding of left and right channels(same as LR mode) Layer 3: the encoding will be done using Mid/Side coding technique.
Joint	If AAC encoder is used with mode Joint the encoding of every frame will be done with Mid/Side or Left-Right Stereo coding technique depending on the data present in the frame. If MPEG Audio encoder is used with this mode: Layer 1: the encoding will be done using normal independent coding of left and right channels(same as LR mode). Layer 2: the encoding will use Intensity coding technique when the bit rate is lower than 96Kb/s for 2 channel setup in combination with normal independent coding of left and right channels, otherwise will use only left and right coding. Layer 3: the encoding of every frame will be done with Mid/Side or Left-Right Stereo coding technique depending on the data present in the frame.
