> Does anyone know of any Linux tools that can create DDP (Disc > Description Protocol) images? Not as far as I know, but at least the spec for the protocol is available: http://www.dcainc.com/products/ddp/ I'd guess that most people in the Linux audio community are mastering direct to CD-R, so no-one has prioritised making a DDP tool yet. I guess one way to do this would be to have a JACK client that just writes DDP to disc, so your mastering chain would be: Ardour/Audacity/whatever -> JAMin -> DDP. I don't know if this is technically feasible. Presumably you'd need some kind of editor tool for the DDP metadata. Cheers Daniel
