Parameter Values Description
Language
The language of the stream when not in dual mono (1+1)
mode.
Language (Left)
The language of the left channel when in dual mono (1+1)
mode.
Language (Right)
The language of the right channel when in dual mono
(1+1) mode.
User Language 1
A custom three-character language code when User
Language 1 is set in any of the language fields.

To meet the MPEG-1 Layer 2 encoding algorithm
specification the audio must not have pre-emphasis
applied. If the input signal does have pre-emphasis
applied, a de-emphasis filter must be applied prior to
encoding.
