Will this be the primary mp3 decoder that replaces Xaudio is future versions?

I wish.

While my decoder outperforms Xaudio under ARM, uses less memory, and provides much more accurate output, I've had no contact with the folks at empeg about this possibility. As Hugo mentions, they've already decided to go with the ARM decoder. (I have no idea how my decoder compares with ARM's atm, fwiw. I do know that I'm not finished with mine.)

You will find my decoder used as the basis for a number of other upcoming products, but this has nothing to do with Empeg Ltd or the empeg-car.

The reason you find support for the empeg-car in my decoder is, well, I own one or two of them and the audio interface on them is almost but not quite the same as the Open Sound System interface; so it deserved its own module.

Lastly, the reason you don't find mention of my decoder on the empeg developer site is... well, I guess two reasons: it has largely been a separate project, only peripherally related to the empeg, and I haven't been keeping the developer site as up-to-date lately as I should.
