I have some multichannel AAC songs that I want to include in DVD-Audio. I have searched but found no related post. Does anyone know if it is worth converting from lossy AAC 5.1 to DTS or including them in DVD-Audio (if possible)? I have read somewhere that DVD-Audio Forum had accepted AAC as one of the acceptable lossy media to be included but it doesnt seem like any DVD-Audio authoring softwares support it including DiscWelder.
Sorry to say, but AAC is certainly *not* acceptable in *any* DVD-A discs. NO lossy forms are allowed in an Audio_TS - that was the whole point. All you can use are LPCM (up to 24/48 in 5.1, or 4.0 in 24/96) and MLP Lossless (up to 24/96 in 5.1). The best you can do is decode back to LPCM and author in something like Cirlinca or DiscWelder. Quicktime Pro ($20) will decode the AAC Multichannel to LPCM multichannel (I think).
