[whatwg] Can AUDIO/VIDEO element have a "balance" attribute

[Philip Jägenstedt]

While I don't strongly object to the suggestion as such, there are 2
things I want to point out.

1. It is not clear (to me at least) what balance means for anything by
mono/stereo audio. What is the expected behaviour for 5.1 audio?

2. Balance is just one kind of audio filter effect. The more "filter"
features are added the tougher the requirements on the user agent and
the media framework backend they use will be.

Is there a use case for having the same LARGE media file played back
with different balance settings? All the obvious use cases would be
short sound effects where creating duplicate versions of the files might
be a better trade-off than introducing more complexity in the API.
