Hello,
thank you very much for the great documents in your resource.
I think that the documents are very good.
I learn lots of things about audio.
And I think that for example: "IEZA: A Framework For Game Audio"
can also help to make [CC] closed captions.
When you want to replace sound with closed captions, it is good to have knowledge
about audio.
:-)
edit: corrected spelling of resources thanks aaron for the tip
