@ShijunS Not sure what you mean with interop. Like echoCancellation, these are opaque abstractions of UA features. Sites can turn each setting on or off, and hopefully be content with the result being superior to the alternative setting.

I don't think they need to sound the same for there to be interop. Nothing in the spec mandates how UAs implement e.g. echoCancellation, nor how or when constraints might conflict, which might happen if support for e.g. mics with controllable hardware echo cancellation is added.

FWIW, Firefox implements echo cancellation, auto gain control, and noise suppression in software. Like the software features, the three boolean settings have no interdependencies; All 8 combinations are allowed. Firefox doesn't implement the volume constraint yet.
