Does any one know which MP3 decoder is used in the Empeg player and can it be upgraded/replaced?

Its software based.

In version 1.0 of the software, the decoder was the XAudio decoder.

In version 2.0 of the software, the decoder is (if I recall correctly) the ARM decoder.

In theory, you could replace the decoder with anything you wanted to code up and compile. The problem is that the actual PLAYER software is integrated with the decoder and is not open-source.

So. If you want to replace the decoder, you must also write your own full replacement for the player software, too. No one has done this for the empeg car player yet.

If you want to replace the decoder, you must also write your own full replacement for the player software, too.

You could replace the decoder without replacing the whole player software. With some clever code in the kernel you could intercept calls to the file system, allowing you to lie to the player when it reads the metadata (telling it that all the MP3 files are WAV files). Then you could intercept calls to load the MP3s from disk and decode them to WAV on the fly.

Not easy, but maybe easier than rewriting the whole player.

Anyway, I can't see any good reason to replace the decoder or the player software, both are excellent.

Yeah there's certainly no point replacing the MP3 decoder - the ARM decoder is one of the best around.

Would Rob be having a sudden attack of modest with regard to the player software ?

Why? He didn't write the decoder.

Hence my comment about his modesty (on behalf of the empeg team).

Thanks guys. I was just checking to see if there were any updates to the decoder - since this can make a difference in sound quality. But since it already has one of the best out there, not need to update or change it.
