Crackling/popping noises in exported video audio

Bryan-Atkinson wrote on 3/10/2025, 5:16 PM

Hey there, I'm using Movie Edit Pro Plus, I think 2020, and my exported video audio has a crackling/popping noise throughout a 9-minute video. It's just an audio interview recorded for radio with some still photos throughout, like a slideshow. I already exported a 70-second version using the same source file for the audio, and there were no audio issues. The audio doesn't sound this way in the software either, just in the exported files.

I've tried resetting the program settings to the defaults, and I've tried exporting it in different formats.

I've seen some responses asking the person to share their settings. If I need to do that, would you mind also including how I access that information to share with you?

Thanks!

Hi and welcome to the user to user forums.

First, make sure the volume isn't clipping for the output by turning on the limiter on the output volume slider of the audio mixer. Internally the volume will not clip when played but could be too hot for exporting.

Next, you could try going into the program's settings and increase the sample rate up two notched steps to make sure enough data gets to the render buffer in time and prevent momentary interruptions to the audio signal path.

Last, when exporting, choose the highest audio bit rate and sample rate available for the format chosen for your export.

Hopefully that will do it.

Thank you Ray!

Sorry for my ignorance. I tried finding an audio mixer. The only thing I found that seems similar is just to increase or decrease the decibels, but that's not what you were talking about.

When I clicked through settings, I didn't see anything like a sample rate.

I do have 48,000 Hz selected as the audio sample rate in movie settings.

Thanks again!

Hi.

Click on the image to expand it.

Let me know if you still can't find settings. The mixer once opened you need to press the effects button on the master channel to get to the limiter. In the audio settings only click twice on the + sign for the sample rate and for now leave the buffer settings alone.

@Bryan-Atkinson

In addition to @CubeAce's comments what is the audio file type eg wav, mp3 etc, the bitrate and sample-rate of the audio file you are importing?

To get this information, use Windows file Explorer, right click the audio file and select properties
