DOLBY DIGITAL DECODER AND AUDIO AMPLIFIER

[guybrush]

Hi to everyone.
I'm thinking to build my own multi channel amplifier for music and also for home cinema. For the audio section, there are a lot of material on the internet. For the digital section, is more difficult to find material. There is some chip from zoran.com but i don't know if the algo is public and can be implemented in any DSP. What do you think about this project?

Bye

There are open source decoders out there that probably could be ported to a DSP.
