Audio Track Mixer Automation Modes
Audio Track Mixer Automation Modes
The Audio Track Mixer in Premiere Pro uses automation modes to control how keyframes are recorded and played back. Understanding these modes is essential for effective audio mixing.
Automation Modes
| Mode | Behavior |
|---|---|
| Off | Ignores existing keyframes; allows real-time control without interference |
| Read | Plays back existing keyframes; does not allow changes |
| Write | Records keyframes continuously during playback; overwrites existing |
| Latch | Starts recording when a control is touched; continues until playback stops |
| Touch | Records while adjusting; returns to previous value when released |
Accessing Automation Mode
- Open Window > Audio Track Mixer
- Locate the dropdown at the top of each track channel (defaults to "Read")
- Click to select a different mode
If the dropdown is not visible, click the hamburger menu (β‘) and enable Show Track Controls.
Recording Keyframes
Automation modes record keyframes only during playback:
- Set track to Latch or Touch
- Press Play
- Adjust faders, pans, or effect parameters in real-time
- Stop playback
- Switch back to Read to hear the automation
Common Misconception
Read mode does not allow manual keyframe editing. It only plays back existing keyframes.
For manual (non-real-time) keyframe editing, use the timeline:
- Expand the audio track in the timeline
- Right-click track header > Show Track Keyframes > Volume
- Use the Pen tool (P) or Ctrl+Click to add keyframes
- Drag keyframes with the Selection tool (V)
Viewing Track Keyframes
By default, Premiere shows clip keyframes. To view track keyframes:
- Click the Show Keyframes button in the track header
- Select Show Track Keyframes
- Choose the parameter (Volume, Mute, or effect name)
