Thinking about what we just discussed on the call, I think setting the
sample rate is an essential feature that should be there in the first
version of the spec, but it might suffice to have just the sample rate of
the AudioContext possible to be adjusted on initialization, for the first
version. That I think would cover the most critical UCs, and we could add
more complex features to v2. What do you think?
