I signed up for it too last weekend after coming across it after doing some research (I had been making a bunch of video recordings a few days prior, and once the videos were added into Camtasia and the audio played back I noticed a lot of background hum coming from my HVAC return outside of the room I'm in).
Was impressed with the Krisp.ai tech as well and probably works similarly to this tool and the other Nvidia solution that I can't try out since I don't have an RTX card (main difference might be the overall training set that Krisp has already run their algorithm through?).
I haven't had any Zoom meetings since purchasing Krisp, but I had been using the built-in mic from my LG Tone headset for those meetings.
Since making those video recordings I've been using my blue Yeti mic (and a pair of headphones connected to the mic for listening) as my primary and I've continued running a bunch of small tests to try and see if I can be happy with using Krisp enabled all the time.
Currently, I don't feel comfortable with leaving it on all of the time though for recordings, particularly with something like the blue Yeti mic which is able to capture pretty rich audio. In my testing, Krisp did a great job of eliminating the background HVAC humming noise, but replaced that issue with two others: some minor (but distracting) hiss/noise between words as I'm playing back the recorded audio, and also currently is limited to 16000mhz frequency (not sure if mhz is correct or not in this case...this is what support shared with me when I asked about audio quality degradation). The support person did respond though and say that the team is working on the increasing the frequencies they are able to work with though so I guess there might be some improvements in the near future on it?
After seeing the latency figures on the NoiseTorch page it makes me wonder if the Krisp latency is similar or not (so far I haven't noticed any latency issues with Krisp).
As far as remaining thoughts...I kind of wish there was a bit more configuration options available for Krisp, but the simplicity of it is also a benefit (for others that might not be as technical and just want a simple solution that does appear to work overall). I haven't gotten it to work for playback needs (it has the toggle for it, but nothing seems to happen when I try and toggle that on). Also, still not sure what the overall differences/improvements with Krisp Rooms enabled (I am recording in a room, but after reading their description/blog announcement page it kind of seems like it's more for conference rooms where multiple people are speaking and extra echo cancellation might be useful? ref: https://krisp.ai/blog/krisp-rooms-launch/)
Since I'm already out with a year subscription with them I'll continue to try and figure out how to use it effectively, but not as excited about it at the moment compared to how I was last weekend initially (impressive overall though...hopefully it continues to improve :-).
16kHz sample rate (= max frequency 8kHz) should be enough for speech only. Human voice is mostly <0.5kHz. You may hear some difference for hisses or for room sounds etc. but I’m sure you’re unable to hear any difference to higher sample rate in a voice chat setting
