Visually impaired audio?

recently i have noticed an option when backingup movies there is a checkable selection in the audio for visually impared does anyone what this is

That audio track is typically dialog and scenic description.

Like with what you can experience with most BBC programs…

thanks for the explanation, i normally uncheck that option

There’s no point in having it there unless you need it.

Particularly if you’re having to compress to fit a disc as this will increase the space available and therefore the quality of the final result.
