Apart of whatever noise reduction is used, the possible full gated (mute) part of this app IMO is a no-go for communication. In (e.g. music) audio engineering this kind of gate can be used to some degree, but if you've ever talked with somebody who's phone used this kind of gate approach, you'll know how annoying it is. Even assuming there should be no additional issues (such as e.g. possible imperfect latency, lookahead, cut off workarounds) the problem with muting by gate is: No voice = no audio or at best noise-damped audio, unfortunately this results in an annoying pumping sound, from silence to voice+noise to silence. It doesn't work for communication. For multi-track audio (video) recordings it does work, since noise is cut away, if no signal is available, too but if a signal+noise is available, the noise doesn't annoy, because the noise is either covered by other tracks, or by the nature of the sound, e.g. instead of vocals, a distorted guitar. If audio recordings are done for speech only, by audio or video studios, then almost all engineers are in favour of keeping the noise, to avoid this pumping by turning noise on and off. Especially when using a "decent microphone", it's not much needed to workaround noise at all. Noise gates almost all of the times are only used, if something else does cover the annoying effect of a noise gate. IOW if e.g. another track, such as a piano backs the singer, but for a speaker only, it's most of the times a no-go. I might be mistaken, since I never used this app. I'm sceptic that it is useful at all, due to my experiences of several decades of audio and video engineering and since I worked as engineer for one of the two famous, well known professional German microphone companies.
