Analysis Events

When analyzing audio, FaceFX uses analysis events to signify important events in the audio.  These are then translated into animation curves via the analysis actor. Below are a list of the events and the event group names:

_AnimEventGroup

• Anim_Begin - Placed at the start time of the animation
• Anim_End - Placed at the end time of the animation

_StressEventGroup

Stress events represent stressed syllables potentially worthy of an eyebrow raise, head nod, or other gesture.  They have a duration scale equal to the current rate of speech.

• Stress_Initial - An initial stress is the first one in the animation or the first stress after a long silence.
• Stress_Final - A final stress is the last one in the animation or the last stress before a long silence.
• Stress_Isolated - An isolated stress has no other stresses in its immediate vicinity.
• Stress_Quick - A quick stress is one that occurs immediately before another stress.
• Stress_Normal - A normal stress is one that doesn't fit into any of the above categories.

_SilenceEventGroup

Silence events signify silence in the animation.  The duration scale of these events equals their duration in seconds.

• Silence_Short - A short silence less than .3 seconds.
• Silence_Medium - A medium silence between .3 and 1.5 seconds.
• Silence_Long - A long silence greater than 1.5 seconds.
