Hi everyone,

I’m not very experienced when it comes to audio settings, and I could really use a bit of help.
Some time ago I managed to fix this issue in Vegas on my old PC, but now I’m working on a new one and I can’t remember what I did back then.

On my own machine the audio sounds perfect, but as soon as I upload the video the sound becomes slightly distorted in the video when the volume is turned up high.

I’m using Vegas Pro 23 Suite 365.

Project Audio Properties:

• Sample rate: 48.000
• Resample quality: Best

Master FX:

• Track Compressor: “Soft limiter”

Loudness Meter options:

• EBU R128 mode
• Loudness scale: Absolute (-23 LUFS)

Render settings:

• Sample rate: 48.000
• Bit rate: 320.000

System specs:

• CPU: Intel® Core™ Ultra 7 265KF (20 cores, up to 5.5 GHz)
• RAM: 32 GB DDR5-6000 (Corsair Vengeance)
• GPU: ASUS GeForce RTX 5070 12 GB
• Motherboard: ASUS B860M-Plus TUF Gaming
• OS: Windows 11 Home

I think there used to be one more option in my old Vegas setup that prevented these little audio artifacts, but I honestly can’t remember what it was.
I know very little about sound, so it’s probably something simple I’m missing.

I’ve attached my latest video.
If you play it at max volume you can hear that it no longer sounds completely clean. One of the first things I say: “You wake up with 5.5 kg of Carbon” (the artifact is very clear there).

Thanks in advance to anyone who can help!
