Editing Audio
For each audio track, the selection in the automation options menu determines the track's automation state during the
mixing process:
Ignores the track's stored settings during playback. Off allows real-time use of Audio Mixer controls without
Off
interference from existing keyframes. However, changes to the audio track aren't recorded in Off mode.
Reads the track's keyframes and uses them to control the track during playback. If a track has no keyframes,
Read
adjusting a track option (such as volume) affects the entire track uniformly. If you adjust an option for a track that's
set to Read automation, the option returns to its former value (before the current automated changes were recorded)
when you stop adjusting it. The rate of return is determined by the Automatch Time preference.
Records adjustments you make to any automatable track settings that aren't set to Safe During Write, and
Write
creates corresponding track keyframes in a Timeline panel. Write mode writes automation as soon as playback starts
without waiting for a setting to change. You can modify this behavior by choosing the Switch To Touch After Write
command from the Audio Mixer menu. After playback stops or a playback loop cycle is completed, the Switch To
Touch After Write command switches all Write mode tracks to Touch mode.
Identical to Write, except that automation doesn't start until you begin adjusting a property. The initial property

settings are from the previous adjustment.

Robbie Carman explains how to use automation modes in Adobe Premiere Pro's audio mixer
Peachpit TV for Video.
Set Automatch Time for Touch mode and Read mode
When you stop adjusting an effect property in Touch mode, the property returns to its initial value. This is also the
case while in Read mode if a keyframe exists for the affected parameter. The Automatch Time preference specifies the
time for an effect property to return to its initial value.
Automating audio changes in the Audio Mixer can create more keyframes than necessary in the audio track, causing
a degradation in performance. To avoid creating unnecessary keyframes, thereby ensuring both quality interpretation
and minimal performance degradation, set the Automation Keyframe Optimization preference. In addition to the
other benefits, you can edit individual keyframes much easier if they are assembled less densely in the track.
1 Choose Edit > Preferences > Audio (Windows) or Premiere Pro > Preferences > Audio (Mac OS).
Enter a value for Automatch Time and then click OK.
