It buffers the data in memory, there is no fixed size. It _will_ attempt
to write out a mixed audio frame each time a matching pair of frames has
been received from both sides; changing that to only write after a
certain amount of data has been received would not be a significant
task. There is a risk of data loss, though, if you do that... but at
least MixMonitor does not sit in the channel read/write path like
Monitor does, so delays in writing the audio don't impact the audio
being bridged across the channels.
