Export Audio Mixdown glitchy artifacts

I’m using Cubase Pro 15 Version 15.0.21. I have recently created quite a small project (no more than ten tracks), all MIDI/VST instruments, from various libraries including BBC SO Professional.

Up until recently, with projects large and small, I have used the Export Audio Function with Real Time Export checkbox Unchecked. However, with my new project I’ve found that when I come to Export the mix I get a very poor result (it glitches and crackles at various places) but it works fine if I check the Real Time Export option. For the past several years I have unchecked this option as a) it slows the process down, and b) when I’ve had the option checked in the past I have run out of computing resource (either CPU or memory - I can’t recall as it was Cubase 9).

Thoughts? It’s not a deal-breaker but it’s annoying! Thank you.

Hi,

Have you tried to increase the Buffer Size, please?

Also, if you’re exporting at a lower bit depth (like 16-bit), enabling dithering can help reduce quantization noise and artifacts.

Thank you @Martin.Jirsak - as always, you know the answer! I’m actually exporting to MP3 so I don’t think I can change the bit depth (I’m exporting to 160 kB/s) but I increased the buffer size from 512 to 1024 and it worked. I’m assuming that this increased buffer size is good for exporting and mastering, but a lower buffer size for recording is better?
