I downloaded the app last night and was able to try it briefly, <10 minutes, today while at work. Nothing certain just yet for feedback, but did take note of some of the settings.
With noise removal at 1 and the voice setting at directional, I didn’t note any real difference. However setting voice to omni, there seemed to be a slight decrease in ambient noise whenever someone would speak.
A note regarding my work environment, I’m located in a telco central office, equipment ambient noise is 50 - 70db depending on where you are standing.
