Premiere Pro dialogue plays in one ear: check channels and panning

Find where the voice becomes one-sided

Save a project copy before changing channel assignments. Two channels may contain different speakers or a backup microphone, so identify them before combining or remapping anything.

Rule out the headphones or speakers

Play a familiar stereo file through the same device. If that also loses one side, investigate the playback setup first.

Then compare a short passage of the original interview with the same passage in the edit. Choose a moment with one person speaking and little competing music so you can hear which channel carries the voice.

Inspect the source-channel mapping

In the Project panel, right-click the audio item and choose Modify > Audio Channels. Check the Media Source Channel assignments against what each recorded channel contains. Adobe's channel-mapping instructions show these controls.

Note the original assignments. Try the intended mapping with a short clip in a temporary sequence, then inspect the affected clips in the existing edit. Do not assume a source change will update every already-edited instance as intended.

Keep separate speakers or backup recordings separate if you still need to mix them independently.

Check the track's pan or balance

Open Audio Track Mixer and inspect the affected track. Adobe distinguishes panning a mono signal into stereo from balancing an existing stereo signal. The numeric center is 0. See Adobe's pan and balance guide.

For a mono voice intended to sit in the center, check it with pan at 0. For a stereo recording with one empty channel, centering the balance will not put the voice into that empty channel; return to the source-channel check.

Listen to a short export

Export a short section under a new filename. Listen to the voice alone, then with the full mix, using the playback device you checked earlier. Confirm that music placement and any intentionally separate speakers remain correct.

If Premiere cannot find the recording at all, use the offline-media relinking guide.
