The optimal specs for an audio interface to use with realtime 3D apps such as Wwise and Unity

Hi!

I've been working with sound design, music production and more recently game audio. I've been meaning to upgrade my audio interface for a while. I work with real-time audio applications that rely on spatial audio processing and throughout my work in my grad program, I've encountered problems with reaching a maximum amount of allowed 'audio voices' in Unity. The default is as some of you may already know, 32, which is customizable; however in my experience with my poor Scarlett 2i4 audio interface, I wasn't getting stable results beyond 40 audio voices. There has to be a lot of different parameters revolving around this issue; but I was wondering if the audio interface has anything to do with it? I couldn't find a minimum recommendations from Audiokinetic on audio hardware. I'm not sure if a lower jitter, or a lower latency would help with these applications at all. I know that most of it is  handled in the CPU its own; but I was wondering if perhaps DSP capable audio interfaces' own CPUs (such as the UAD Apollo series as an example) assisted in this at all. I do have an i7-9770, which should be plenty; but I'm sure as some of you know, working with an increased number of audio sources in complex geometrical environments with many different audio sources playing at the same time - while also receiving real-time spatial processing (from propagation to HRTF representation etc... occlusion, air absorption and all that jazz) can be tough on the CPU on its own; which may yield to be not so feasible in actual game design scenarios.

I've been using 3D realtime authoring applications for research purposes throughout my time in school, and I intend to push the envelope on what we can get the most out of our spatial audio technologies such as Steam Audio (which I primarily work with and can't wait for the Wwise version). I was wondering if hardware had anything to do with the audio capabilities we would possess within our computers.

 

Kind regards,
