Stereo to Mono - Premiere Pro

If you have a stereo audio file or a stereo audio track in a video file and you only want to use the left or right channel Premiere Pro has multiple ways of accomplishing this.

A common a example would be a stereo file with audio on the left channel and silence on the right channel.

Effects

• The Fill Left or Fill Right audio effects can be used to duplicate the audio from one channel to another.
• For example, if the file has narration on the left and silence on the right the Fill Left effect would duplicate the left channel audio to the right channel.

1. Select the audio clip in the Timeline.
2. Open the Effects panel.
3. Expand the Audio Effects folder.
4. Drag the Fill Left or Fill Right effect on the clip in the Timeline.
   • Fill Left duplicates the left channel onto the right channel.
   • Fill Right duplicates the right channel onto the left channel.
5. Now the audio will playback on both channels. The waveform display in the Timeline will only show audio on one channel.

Breakout to Mono

The Breakout to Mono command creates mono audio master clips from a stereo audio or video clip. The clips reference the original file. No new media is created.

1. Select a clip in the Project panel.
2. Go to Clip > Audio Options > Breakout to Mono
3. Two new clips will be created in the Project panel.
4. The new clips will have the original filename with either Left or Right added to them.
