Define a condition for when a track should be active and not.
Can either be a function callback or a configuration object.
If a function is used, it should return a boolean
for whether
or not the track should be active. The function is called for
each audio event, and receives a parameter object with time
,
and potentially point
and value
properties depending on the
track. point
is available if the audio event is related to a
data point. value
is available if the track is used as a
context track, and valueInterval
is used.
