It has a delay before the audio comes through.  When the audio enters
the buffer, VLevel starts smoothly adjusting the multiplier, which is
applied to the audio as it leaves the buffer.  The data in the buffer
(the future) is used to compute the multiplier for audio as it leaves
the buffer (the present), so the buffer's necessary.
