Possible to author 24/96 LPCM Audio DVD?

[timbabb]

I'm thinking of getting DVDSP (DVD Studio Pro from Apple) for the purpose of authoring 2-channel high-res audio DVDs. (Not DVD-As, but rather DVD video (audio only). The video will just be a still shot, but I want the audio to have 24 bit / 96 kHz quality. Will DVDSP allow this without subsampling the audio data?

Secondary question - My audio files are 24/96 AIFF files, can I just use these with DVDSP or will they need pre-processing?

Thanks in advance!

You need to pre-process with A.pack (if you want AC3 - limited to 16/48 ), which comes with DVDSP, or you can just leave it in AIFF, I believe, and DVDSP will make it DVD standard PCM audio. The DVD Video spec allows 24 bit, 96kHz audio (at least with PCM - the encoding method used by AIFF), but you will be limited to 6144kbps. Here's a brief reference site:

DVDSP does support Stereo PCM at 24/96, at 4608kbps, according to it's specs:
