The Lync and other specs are constructed to provide signal optimal for voice
processing algorithms such as AEC, Noise canceling etc. Other streams may have
or sometimes need to have enhancements such as multiband compression, surround,
voice clarity, virtual bass, etc. So, it’s not ‘cheating’ but complying to
different requirements of different modes.
I don’t see a danger to have info on the stream source to be able to apply an
appropriate processing unless you want a single processing mode for everything?

I support this request since voice apps need a specific processing applied in
APO to be compliant with e.g. Lync spec.
But at what point does that cross the line into cheating? The Lync specs were
(presumably) carefully constructed to provide an optimal signal for video
conferencing. So, wouldn't you want to do that processing for every video
It seems to me a dangerous slippery slope to have "Zoom" mode and "Skype" mode
and "Lync" mode and "Teams" mode and "WHQL" mode.
