The primary Clear Audio requirement should read:

(CA-1) Support clear audio as a separate, alternative audio track from other audio-based alternative media resources.

The salient point is that we do not require user agents to create clear
audio. Rather, clear audio is, or is not produced at the same time as
the primary media resource audio is mxed down. Thus, it becomes simply
another alternative media resource to be correctly identified by
metadata.

Any user agent which wishes to expiriment with "reverse karaoke" type
strategies to create something approaching clear audio is welcome to do
so, of course. However, that is not how we expect clear audio to be
generated, nor is it how clear audio is generated today.
