MP3 conversion: created file is offset

On converting a 24/48 wav file to mp3 using the render function - no plugins on master buss, the resulting file is offset by around 25msec. Since the file being generated is a click, the band is getting a little confused…

Any idea why this happens and how to prevent/fix it?

It’s normal in MP3 and AAC. Added silence at the beginning is called Delay. Added silence at the end is called Padding.

Do you have to use MP3?

Thanks, that explains it perfectly. It’s a 3 hour show, so didn’t really want to download the existing stems which are in wav - I’ll just trim the click files, zip and send through
