Audio crackling problem when exporting

[Florian Cedard]

Hello, I'm writing to you because I have a major problem when I export my projects in MP3 or WAV.

I find myself with a lot of audio crackling, and the longer the track is, the more there is.

I tried to export by changing the Buffer Size of my audio driver (512 / 1024 / 2048) but the cracking persists.

Is there a solution?

I could share my latest audio export so you can hear my problem

Thanks in advance

It would be help people help you better if you shared your system specs and settings.

Buffer settings have zero to do with export. Is this an ASIO interface or On Board system audio?

Hello and thank you for your answers.

So I use an ASIO interface (Steinberg UR44).

As for my hardware : 
Asus TUF B360-PLUS GAMING 
I7 8700
32 GB of ram
Samsung SSD 860 EVO
Nvidia GeForce GTX 1070

FWIW, I noticed that certain plugins (?) apparently didn't like the default "200ms" bounce buffer size in the Export dialog. I'd get weird glitching in the output file (both wav and mp3), in a non-repeatable manner. Not crackling per se, more of a stutter effect.

Bumping the Export bounce buffer down to 60ms cleared that up for me.

Note: This was in 2012.11. Haven't tried pushing the buffer back to 200ms in 2012.12 – why look for trouble.

I may have a solution, I have "frozen" all my tracks and it seems to work for now.

I'll keep you posted in time

Not sure this is correct. My understanding is the bigger the buffer the safer it will be for rendering the data. Would be interested to understand this better.
