When I use Wavelab for mastering with effects on clip / track/ master section in a montage destined for CD burning and files exports, my ideal workflow is to render all of it in a 24 bit montage first. This becomes the master from which I will dither to 16 bit to produce a DDP, burn a CDs, or export Wav 16bit and mp3, but also export 24 bit files for platforms that require it
Why render first ? Since I use some CPU intensive plugins, that means I do the treatment only once
The problem is that straight rendering will loose isrc codes, CD text. to keep them I do a CD image and Cue sheet and import it back into a Montage. Luckily this works in 24 bit, but why make it so complicated ? I can’t find a logical reason why rendering should loose all this info.
There is also a serious drawback of importing back the bin-cue image, I always strip cd-text of accented characters like éèù etc. My new montage lacks the accents in the clip titles, so in turn file exports done from there lack the accents as well
