I'm not sure the best way to explain the scenario so I'll do my best, please don't hesitate to ask if I'm missing something obvious to help build the picture.

My problem is I've edited a video in Premiere (CS6) and when I export it part of the audio is missing and I cant seem to find any reason why.

The audio that is missing is at the start and end of the video, it's a stereo piece of music. The rest of the audio is mono (and renders out no problem). When I'm playing back the preview everything plays as expected, nothing seems to be muted or turned down. The settings on the export are set to match the quality of the music track that is missing.

Any ideas why I can't get that audio to render? It's really frustrating! Cheers.

EDIT: I've tried rendering in different formats and sample rates. No joy.

  • I'm not familiar with Premiere, anyway, a couple of things comes to my mind: what happens exporting only the audio, it plays as expected? have you tried exporting the video with mono audio to see how it plays? are the system audio settings configured properly (number channels/volume per channel/ballance)?

  • In what format are the audio files when you import them? (mp3, wav, etc.)

  • The file that isn't rendering out is a .wav with the following details: Source Audio Format: 44100 Hz - 24 bit - Stereo Project Audio Format: 44100 Hz - 32 bit floating point - Stereo The rest of the audio that does render is from a quicktime avi.

Managed to dive in to it and root out the problem. Despite all the audio playing in the preview there was actually a channel solo'd in the audio mixer. I only noticed this when I ran an update on Premiere, de-authorised and re-authorised it (because of another issue that happened) the audio in the preview started to play back correctly as per the track solo status.

Thanks for those who looked at the question and tried to help.


In my case, it was lack of space on the drive with the Project (I did not recognize it). It probably could not somehow create the audio peak file. I created more free space and all audio tracks were exported correctly.
