I suggest that CA-4 can safely be termed 'may.'


1.)	This will only be possible from the browser/useagent if some API
mapping to OS provided audio controls is created.

2.)	Any user that significantly benefits from this kind of audio
tweak is very likely to have either or both:
	a.)	A profile on their computer that creates the correct
emphasis/de-emphasis.

	b.)	Most likely of all, direct control in hardware playback
equipment to create the appropriate audio representation.


Someone who benefits from this feature will need to apply it to
everything they listen to, so the burden should not be assumed on the
browser/useragent too directly.
