Actually, the Xbox One has complete audio chip(s) for games that can handle 512 simultaneous voices and will capture voice at 24 KHz PCM, and several more for Kinect processing.   We still don't know what some of the extra co-processors do.

As I understand developers can take up to 4 of the CU's of the GPU for sound processing on the PS4.  As we know the PS4 will have in game chat, and this chip seems to be assisting with that as well.

The Xbone audio chip was made to works with the Kinect feature all the time.... of course there are simple games tasks too but if you need to do any raycasting audio you will need to use GPU CUs on Xbone too.

PS4 audio chip do the same except the Kinect part... so the voice recognication will be ready only when you are not playing a game (I guess)... and if you need to use raycanting auido again you need to go to GPU CUs.

I don't see advantage here... both will be free audio processing without need to use GPU or CPU... anything more complex in audio terms will need to use the GPU.

EQ/Dynamics/Filter/Mix part is not for Kinect. It's for in-game sounds. As I said earlier, it's not that massive hit when it's done native on CPU, but they decided to offload it to separate DSP.
