Audio quality differs in source window vs timeline?

[tennet78]

Hi,

I just experienced some weird problem with the audio quality in Premiere CC 2019. I have added a mp3 song to the timeline and when playing back the video in the timeline then the audio quality of the mp3 sounds very poor.. but if I playback the same audio file in the "source window", then it sounds normal (high quality) again... Any idea why the sounds quality differs when playing it back in the source vs timeline window?

I also tried to export a video clip and the mp3 audio sounds bad in the exported video also.

I'm using a Macbook Pro (2018) and Adobe CC 2019.

Hi again, I just found ”the fix” in another thread here. My project file was probably corrupt..  When I created a new project and copied everything over, then sound was normal again. Problem solved.

I also had this problem

• Audio in source window = Excellent quality
• Audio in timeline = Poor quality

For me, the issue was that some tracks in the timeline were set to "mono". So, I needed to create a new sequence where all the tracks were set to standards. Here's a video I found that solved my problem: https://www.youtube.com/watch?v=ccU90lkQxLY
