Filtering Settings

The following settings are available in the Filtering submenu.

(a) Audio Level Indicator(b) Tracking Mode box(c) Frequency Graph(d) Listening Mode box

Tracking Mode box
  Select the tracking mode. In Amplitude tracking mode, a keyframe is generated at each frame, following the envelope of the audio signal. In Transient tracking mode, a keyframe is generated for each audio transient (sudden rise in amplitude), provided that the signal rises above the specified threshold.
Listening Mode box
  Select Pre Filter (the audio as it was imported) or Post Filter (the audio with any changes made) monitoring when playing back the audio media. This setting does not affect the analysis.
Frequency Graph
  A visual frequency representation of the audio signal being tracked. The audio display is always Pre Filter.
Frequency Range Preset box
  Select a frequency range preset to determine the cutoff frequencies for Low and High filters.
Low field
  Displays the lowest frequency of the input signal used in the analysis (also represented by a slider under the frequency graph). Use the slider or field to adjust the low value.
High field
  Displays the highest frequency of the input signal used in the analysis (also represented by a slider under the frequency graph). Use the slider or field to adjust the high value.
Threshold field
  (not shown) Displays the value at which a keyframe is generated each time the signal rises above it. Available only in Transient tracking mode.

TipStart with a high threshold, and lower it until all required peaks are detected.

Floor field
  Displays the minimum level of the audio media to be considered for the analysis. This setting is typically used to remove analysis noise between audio transients. Available only in Amplitude tracking mode.
Inertia field
  Displays the rate at which the signal decreases after a transient. In Transient tracking mode, the Release field can be increased to avoid the generation of several consecutive keyframes when the transient is not clearly defined in the input signal. Conversely, if the Release field is set to 0 ms, each transient rising above the threshold generates a keyframe, even if each occurs within a few milliseconds of another.
Audio Level Indicator
  A visual representation of the audio level and the current Threshold or Floor value. In Transients tracking mode, the arrow turns red to indicate a peak.
Reset box
  Select Reset to reset the Filtering submenu settings only. Select Reset All to reset all of the Audio tab settings.

NoteSome of the settings in the Filtering submenu are repeated in the Mapping submenu so that you do not to have to switch tabs to change the settings. The same settings are reflected in both submenus.
