List of Audio Interfaces

[Patrice Brousseau]

FWIW, I get these results:

Latency  8.4 ms with Frame Size 1.0 ms, 44.1k,
Focusrite Scarlett 2i4 Gen. 1 (USB 2),
MacBook Pro 2015, macOS 10.15.3 Catalina

Latency 11.4 ms with Frame Size 2.5 ms, 44.1k,
Focusrite Scarlett 2i4 Gen. 1 (USB 2),
MacBook Pro 2015, macOS 10.15.3 Catalina

I wonder why some people are getting latencies of 20 ms +.

Did you installed the low latency kext?

Thanks, but no.  My unit is Gen. 1.  I may give it a go later, but will likely try to buy a Thunderbolt interface instead. :0)

Won't work with 1st gen. Your numbers looks good anyway.
