1. (Optional) Choose Edit > Preferences > Audio
(Windows) or Adobe Premiere Elements 9 >
Preferences > Audio (Mac OS) (Figure 15), and set a
value between 1 and 2000 milliseconds for Minimum
Time Interval Thinning to limit keyframes to intervals
larger than that value. If you don’t want to hear audio
while you scrub audio, deselect Play Audio While
Scrubbing.
2. In the Timeline or Sceneline, click the Audio Tools
menu and select Audio Mix (Figure 16) or choose
Window > Audio Mixer.
3. In the Monitor window, drag the current-time indicator
to where you want to start mixing audio.
4. Click Play in the Monitor window and adjust the
controls in the Audio Mixer (Figure 17) to
automatically add keyframes to the track:
• To adjust balance for a track, turn (drag) the
Balance control left or right.
• To increase the volume for a track, drag the Level
control up or down.
Note: You can specify the spacing of keyframes in the
Audio preferences.
To mute a track while mixing, click Mute. This option
does not mute the track permanently—only while
mixing.
5. Close the Audio Mixer when you are finished mixing
the audio.
