I am consolidating my tracks to send off for mixing. I recorded in 96khz. The mixing guy wants 24bit 48khz. I know there is an option for bitrate under mixdown, but I don’t see and option under export selected tracks. Is there any way to change the exported file bitrates without converting whole project? I hope this makes sense.
1st things first … get a different mixing guy!
He doesn’t know what he’s doing! 
He should be doing any conversion he requires!
anyway…
you can batch export in Audio Mixdown (select the required tracks from the list on the left) and set the Sample Rate and Bit Depth.
Ah yes…didn’t catch that when replying your other post.
Export selected tracks is for importing back into cubase projects only.
