I don’t think that DDPs support 24-bit and I wouldn’t trust anybody on the receiving end to be able to keep a DDP image at 24-bit to cut the vinyl from even if Wavelab could somehow make a DDP 24-bit.
For MFiT version, you could just render each region (CD track) as a 24-bit WAV and have Wavelab add the numeric prefix to the start of the file name. Just remember to adjust your dither plugin to 24-bit from 16 . You can set the metadata options to add the song title to the metadata without the numeric prefix as well so the number doesn’t show when you load into software if you don’t want it to.
For vinyl masters, I usually just render a long continuous 24-bit WAV file from the montage for each side of the record and include a PDF of where the track IDs are. This way all the spaces between songs stay in tact. After I have my settings dialed in for the vinyl master, I usually have to make a montage (save as) for each side of the record so that the times on the PDF for each side match the audio file and start from zero.
For side A montage I simply delete the regions that are for side B and add a CD end maker where side A ends. For side B montage, I have to delete all the regions for side A and slide the side B regions and markers to the start of the montage (zero).
I’m used to doing this by now but I have always wish there was an automatic way to generate a vinyl master using 1 montage, resulting in one WAV per side with times that match the PDF and audio file.
For example, if you make a WAV for each side using one montage laid out like a CD master, the times and IDs for side B will show much higher times than the audio file because the audio file will start at 0 but the times include all the audio from side A.
