Audio Graph: A graph displaying a visual representation of the Source Audio data analyzed
by the behavior per frame.
During playback initiated by the Play button beneath the Audio Graph, the selected
Source Audio data appears. If audio analysis is being performed, a progress bar appears
in the Audio Graph area.
The values of Low Frequency, High Frequency, Floor, and Ceiling can be set by dragging
the small triangles along the bottom or right side of the graph. Or they can be set
numerically using the four sliders underneath the graph to isolate specific frequencies
and values for analysis.
Low Frequency: Sets the low frequency threshold of audio analysis. Only audio frequencies
above this value are analyzed. Values range from 1 Hz to 22,050 Hz.
High Frequency: Sets the high frequency threshold of audio analysis. Only audio
frequencies below this value are analyzed. Values range from 1 Hz to 22,050 Hz.
Floor: Sets the minimum value of audio input, below which results are ignored. Values
range from 0 to 1.
Ceiling: Sets the maximum value of audio input, above which results are ignored. Values
range from 0 to 1.
Smoothness: Sets the window size to smooth the result curve. Any value other than 0
triggers a keyframe reduction with an error tolerance of 1%. Values range from 0 to 10.
This parameter is only available if Respond To is set to Amplitude.
Note: Depending on your audio file, Smoothness values greater than 7 may result in
audio playing out of sync.
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 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 list below.
