Does it make sense for this to be a static? Won't the available sample rates
vary by AudioCapturer implementation? Or does this refer to the sample rates
that our protocol supports? Or that the current client implementation supports?

It represents the rates the current client implementation supports, so it should
be the same across all platforms.
