Hi,

I found this morning this information.

Hopefully it will work on the Empeg....

Besides licensing, I would worry more about this statement:
Quote:
What processing power is required for decoding and encoding MP3 Surround?
The Fraunhofer IIS MP3 Surround encoder causes workloads approx. 50% higher than the Fraunhofer MP3 stereo encoder. Decoding six channels with the Fraunhofer IIS MP3 Surround decoder needs around three times the processing power of decoding stereo MP3.


But it does sound very cool. Maybe I'll have to start checking out the DVD Audio available.

Unlikely to work with the empeg unless it's backwards compat like MP3 Pro and even that was a bit naff. It'd play but you'd end up with something 1/2 the bitrate since the new Pro bit would just be ignored. Even if we some how managed to get a licensed codec in, the empeg is only stereo

I myself am waiting for 360-channel surround sound. 5 channels... BAH!

The Ogg Vorbis spec can already do more than two channels anyway. Of course, I don't think that anything actually implements that feature.

No. The empeg's output hardware is ordinary stereo, using a Philips DSP chip that's meant for ordinary stereo car CD players. There is no way on the empeg to have more than two channels of output.

So no matter what tricks you do in software to decode multi-channel information, there is nothing you can do to make more than two channels play out of the empeg's outputs.

No. It's connected to the DSP still.

Besides that, I believe it needs to be configured differently to output surround. Since all settings are done with hardware, it would not be easy to change.
