Lots of the projects I’m getting are coming in at 24bit. I master at the same bit/sample rate in the Audio File view and then build the release in an Audio Montage and use that for the creation of all the different final formats. When burning a CD you dither down to 16bit, easy enough. When rendering for vinyl or an “HD” digital format I want to keep it at 24bit but I’m curious…:
The Audio Montage is a 32bit audio streamer. This means that it non-destructively upscales all audio used within it to 32bit, right? So, even though the audio used in the project is actually at 24bits, I would need to dither to 24bit if I wanted to render out at 24bit because of this upscale and subsequent truncation? And I would also need to dither to 16bit even if the original mixes and masters were at 16bit?
To be safe I’ve done it that way so far, and all the audio sounds the same after dithering as it does after mastering in the File View, but I’d rather not add noise if I don’t have to.
Just out of interest, why is the montage a 32bit audio streamer? Why not have the audio dictate the bit rate like in the File View?
