By vector operations do you mean using something like the Accelerate framework? or SSE/NEON primitives? or just retooling your code so that your compiler can make attempts to vectorize when possible?
I'm a bit new to this stuff, so I'm not exactly sure to be honest! It looks like he is piping several array operations through Accelerate, and I suspect there is at least one part of my render callback function that would finish faster with appropriate vectorization.
If anyone has any relevant tips about how the Obj-C LLVM or whatever it is actually works and what it means for low-latency audio, please do share. My current strategy is ruthless and minimal static allocation but I don't know what is best.
