“There’s dedicated audio hardware,” he revealed. “The principal thing that it does is that it compresses and decompresses audio streams, various formats. So some of that is for the games – you’ll have many, many audio streams in MP3 or another format and the hardware will take care of that for you.

“Or, on the system side for example, audio chat – the compression and decompression of that.”

He also added that the GPU can be useful to do different types of audio processing.

“It really does come down though to the amount of parallelization that is natural to perform for that algorithm, and that does vary greatly depending on what you are doing specifically in your audio processing. I think that as you go forward we will see a hybrid approach in a couple of years where certain aspects of the audio are being done on GPU.”

Earlier he revealed that PS4 GDDR5 RAM latency was not much of a factor since the GPU could handle it.

thx for the info...

Nice post. How many surprises is there. About the hardware.
