Amiga soundcard Prelude vs Prisma?

[Matt_H]

Given that the Prisma isn't available yet, I hesitate to suggest one way or the other. I think most of the Prelude's power and versatility comes from AHI. The Prisma will have a much more powerful processor, but if it doesn't have AHI I think its utility will be limited...

Ian, can you tell us more about the Prisma's software? I think there's still a lot of confusion as to how that will work (well, on my part at least ). How will programs take advantage of the Prisma?

[Matt_H]

So it sounds like it's AHI for basic audio out, and then prisma.library for the complex decoding?

[Matt_H]

Thanks for that explanation! I guess, concept-wise, it doesn't sound like it's vastly different from a Delfina or another of the old soundcards with a hardware MPEG decoder (but without recording ability?).

I think I mentioned it when the board was announced, but I would like to suggest again an mpeg.device compatible software interface at a later date/in addition to/instead of an MHI driver. I don't think MHI was used for anything other than AmigaAMP, whereas there are a few more programs that can use mpeg.device (including MHI). I just discovered this one which sounds really cool and could open up the possibility of hardware decoding to a lot of old software.
