Exported audio sounds different from timeline!

[#1]

My audio sounds perfectly fine when i play it on my timeline. However, after exporting, the exported audio sounds very different and muffled.

I added the Denoiser effect as well as the Parametric EQ effect on the audio in the timeline. Thinking that this might be the problem, i erased the effects and when it exported, it didn't sound muffled anymore. But the problem is, without the denoiser and EQ effect, the audio sounds bad. So i really don't know what to do! The denoiser and EQ effect sound great on the audio in the timeline, so i'm very confused and don't know how to fix it!

PLEASE HELP!!! IT'S VERY URGENT! I have to submit this video tomorrow and i'm at loss.

People have had issues with the denoiser for a while. Try clearing the Media Cache and check this out: https://community.adobe.com/t5/premiere-pro/denoiser-problem/m-p/4162943#M10698

Hey, I've been having problems recently as well, but I found a solution that works for me. Are you using keyframes in the audio file? I noticed when I added an ease out/in, my keyframe would change to Bezier. I switched it back to continuous Bezier or Linear, and the export was accurate to the timeline. Hope this helps!
