Sensitivity: Sets the sensitivity of the transient detection. Values range from 0% to
100%. This parameter is only available if Respond To is set to Transients.
Channel: Sets the audio channel to analyze. Value can be set to Mix/Mono, Left, or
Right.
Note: With a multichannel audio file used as a source, Mix/Mono must be selected in
order for audio analysis to be performed properly.
Peaks: Sets the way the key points are linked when drawing the peak curves
generated by the audio analysis. Value can be set to Sharp, Smooth, Square, or
Continuous.
The different peak types are described in the table below.
Note: The examples below are for reference only. Because the audio behavior does not
generate keyframes, you won’t see actual keyframes in the Keyframe Editor.
Peak type Example Description
Sharp Each peak of the animation curve is described
by three keyframes with a straight line drawn
between them. A selected keyframe has no
tangent handles.
Smooth Each peak of the animation curve is drawn by a
single keyframe with a Bezier curve. A selected
keyframe has a tangent handle to change the
shape of the curve.
Square Each peak of the animation curve is drawn by
four keyframes. A selected keyframe has no
tangent handles.
Continuous This method behaves like Smooth
interpolation, but without access to Bezier
handles, as they are calculated automatically
from peak to peak.
