I'm using a mid-level Focusrite interface and getting some eco/latency while tracking voice (monitoring with headphones in real time). Everything I've read says to mute the input or play with latency in the DAW, but for the life of me I can't figure out how to do either. Anyone have suggestions on specific steps I could take to remedy? My laptop is pretty souped up, so should be able to handle the load.

Focusrite 18i20 (with control app), modified Macbook with High Sierra 10.13.4, Sound Forge Pro Mac 3.
