Dual Mono [1 + 1 (L/ch1, R/ch2)]
This was introduced to allow two mono channels to be carried in the same
bandwidth as stereo signal. The main use for this mode is for multi-lingual
transmission where the decoder selects which language to decode on left or right.
Joint Stereo [2/0 joint]
This option is available for MPEG-1 Layer II only. This applies a technique called
intensity coding. The human ear is not as good at locating higher frequencies as it is
lower ones. The use of this mode may introduce more artifacts than stereo.
Stereo [2/0]
This mode treats the incoming audio signal as a left and right channel that the
viewer will listen to simultaneously. Practically, these stereo signals can be
uncorrelated where they are coded separately or related where they combined into a
sum and difference channel and each is coded separately.
6/8 Channel Phase Aligned Audio
For a description of the Phase Aligned Audio (PAA) mode, see Chapter 3, Getting
Started.
