Re: [LAU] Discussion: Future CPU-technology vs. realtime audio?

You're just going to have to buy the same hardware that high frequency
machine stock traders are using. Their latency requirements these days are
even more demanding than audio, and they've got the money to spend.

But also, you're likely going to need to forget hardware targeting mobile
(or more generally, battery powered) use cases.
