The number of possible simultaneous sounds for each of the assigned AudioStreamPlayers.
For example, if this value is [code]32[/code] and the animation has two audio tracks, the two [AudioStreamPlayer]s assigned can play simultaneously up to [code]32[/code] voices each.

Ordinarily, tracks can be set to [constant Animation.UPDATE_DISCRETE] to update infrequently, usually when using nearest interpolation.
However, when blending with [constant Animation.UPDATE_CONTINUOUS] several results are considered. The [member callback_mode_discrete] specify it explicitly. See also [enum AnimationCallbackModeDiscrete].
To make the blended results look good, it is recommended to set this to [constant ANIMATION_CALLBACK_MODE_DISCRETE_FORCE_CONTINUOUS] to update every frame during blending. Other values exist for compatibility and they are fine if there is no blending, but not so, may produce artifacts.
