I have been mixing ITB but considering building a summing mixer to mix OTB. I would think the best signal path would be to take buses out of the daw, mix together in summing box then run through any analoge processers of choice, and then resample into anouther daw running at 16/44.1 thereby achieving the best sound quality by avoiding any SRC at the same time. IOW you've completely avoided any SRC, yet haven't added any DAC/ADC from what it would take to mix outside the box alone. How do people then get these results when sending their mixes off to a mastering engineer? I don't imagine ME's want to see mixes already converted to 16/44.1, yet if I wanted to mix OTB this would be my only option unless I was to resample at hi res and let the ME do the SRC, resulting in one more DAC/ADC than necessary, assuming the ME is downsampling. Either way there is more processing than necessary. Seems to me the only way to accomplish this would be to master the mix at the time of mixdown, anything else would be a compromise. Keep in mind I am talking ideals here, if I wanted to compromise I'd just keep mixing ITB. To me this all seems to point to the fact that maybe the line between ME's and MIX Engineers will be or should be a little more blurred than they are now. Possibly integrating the two or maybe working together on the same mix at the same time to get the best results possible. Any thoughts?
