I can’t measure the latency with the built in tool because without an interface with i/o, my laptop only has 1 1/8" jack which can be assigned as either i or o but of course not both.
Just comparing the audio from both my laptop and my keyboard, playing a percussive sound, I can’t really hear any latency.
Which… gets me back to my original questions:
Would I automatically get better latency with a $100 interface?
Let’s assume based on your experience David-san that yes… automatically it’s a positive.
Would I get even better latency with a $900 interface (RME/Apollo)?
Which is to say… in this situation where all I care about is audio out of Gig Performer and not recording or other issues… what if any are the latency advantages from one interface over another?
Are there any benchmark tests of the latency of interfaces?
So this is something pretty common to graphics cards, where you run a software test and report exactly what the FPS or CUDA performance is. In theory the Gig Performer software test (requiring a hardware loop in place) does an accurate job of measuring this. All things being not equal, if someone had access to multiple interfaces testing their latency using the same computer… you would be able to demonstrably measure the latency performance of one interface vs another. In other words… a bench mark test. I think this would be very useful.
