The following settings are available in the Mapping submenu.
- 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.
- Link To Channel button
-
Enable to map the tracked audio to the selected animation channel. An ‘a’ appears in the Channel hierarchy next to the name
of the linked channel. Multiple channels can be selected simultaneously.
- Channel Name field
-
This locked field displays the name of the selected channel being linked to the tracked audio. Multiple Channels is displayed
if more than one channel is selected.
- Min Value field
-
Displays the minimum value at which keyframes can be set in the linked channel.
- Max Value field
-
Displays the maximum value at which keyframes can be set in the linked channel.
NoteThe minimum value can be higher than the maximum value to get an inverse mapping of the tracking mode in the animation channel.
- Attack field
-
Displays the number of frames needed for the channel to reach the Max Value before a transient. Available only in Transient
tracking mode.
- Release field
-
Displays the number of frames needed for the channel to reach the Min Value after a transient. Available only in Transient
tracking mode.
- 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.
- Reset box
-
Select Reset to reset the Mapping submenu settings only. Select Reset All to reset all of the Audio tab settings.
NoteSome of the settings in the Mapping submenu are repeated in the Filtering submenu so that you do not to have to switch tabs
to change the settings. The same settings are reflected in both submenus.
