The DSP tests drive the same files the page loads, so there is no second
implementation to drift. The room tests put two real browsers through a
real room with a synthetic microphone, which covers everything except the
acoustics: slot rotation, leave and rejoin, and the stalled-device case
where a chirp must be withheld rather than sent late.
