For the last few years I've been using Nuendo 3 for mixing projects. Once the mix is sounding good, I use the Mixdown feature in Nuendo to create a stereo wav file (still at 48hz/24bit) before mastering in Wavelab.
The other night I was mixing a track down. Playing back the mix in Nuendo everything sounded great. Playing back the stereo mix file I created using the export mix feature, a lot of the depth seemed to go, top end was a bit scratchy, and everything sounded a bit scooped out in the mid range.
I tried a different track and the same thing was evident, the stereo mix lost a lot of sheen once the compiled track was played back.
In the end I recorded straight to CD playing back the mix through the desk to a CD recorder, then ripping the CD audio to wav to master in Wavelab.
Any ideas what might be causing Nuendo to create a mix that sounds noticeably different in the compiled stereo wav?
I've always mixed to a stereo file this way to be able to master at 48/24. Is there a weakness in the Nuendo mixdown process or could it be my audio interface causing issues (Moto 24 i/o)
I also use a Focusrite Liquid Mix which does cause the mixdown/export to happen in real time. Could this be causing an issue?
For the time being I'll mix straight to CD as the results are much better, but I dont remember there being such a noticeable difference on previous mixes so interested to try and find out what is wrong.
