Krisp work with most of the video recording conferencing apps but you’re able to employ it with any app that lets you pick out an audio source . I tried it with Skype , Slack , and evenAudacityand it worked fine .
To test matter further , I dug up some old voice - overs with awful background noise just to see if it could filter out those noises and to my surprise it did eliminate all the disturbance when I play audio on the VLC media player using Krisp as the audio gimmick .
Testing
I set up two tests to see the performance of Krisp app , first was a pre - recorded audio sample with noise build in . Second , is a bouncy Skype call with background haphazardness and reverberate to examine the real - time noise reduction organization .
Test 1 : Parsing the audio Krisp
The first test require me sitting in a elbow room with an AC running in the background . I simulated a dealings environment by playing the sound through my phone . I then proceeded to read the audio sample in uncompressed WAV formatting . After that , the audio sample distribution was break away through Krisp for noise reduction . As you could see(hear ) , Krisp does make a considerable difference . However , there is a slight distorted shape in the audio quality which is partly due to the re - recording process .
Hey this is go to be a short tryout to see if the Krisp App works . I am sitting in a fairly silent room but the AC play in the background is loud . I ’m also start to sham other background noise like the traffic using the telephone , simultaneously crumpling a plastic bag , and dropping plastic cups on the tabular array . Hopefully , this mic picks up all the noise and we ’ll then attempt to eliminate those sound using Krisp App .
Score : 8 /10
mental test 2 : Krisp during a Live Skype Call
I made a Skype call and selected the reservoir as Krisp mic in the options . I plough the noise cancellation Off and On during the call and you could see the remainder in the video below . There is a pregnant deprivation of noise but the voice also get hold of a hit . I found that even though Krisp tries to keep the original voice as original as potential , Skype pack together the audio quite a spot which results in a misrepresented and sometimes even incomprehensible speech . Krisp works fine when you have fewer noise sources such as your dog bark in the background knowledge , building work outside the sign of the zodiac , etc .

grudge : 7/10
Results
I could n’t upload the sound samples densification barren and that ’s why the noise reduction on the picture attached does n’t voice radical . When you use Krisp on your own computer , the timber is going to be much safe than what you heard in the picture above . Overall , if I were to designate a grade to the filter audio , it would be around 80 - 90 % . I give this grudge because the noise decrease is done in real time , the data is processed on the data processor and the results are very impressive . However , I do feel there are some noise elements which cause the algorithm to eat relevant information as well . you could see(hear ) the distortion in the audio on the samples attached .
In the liberal adaptation of Krisp , you could mind without racket . To Speak and Listen without the noise you need to advance to the premium version that cost $ 20 per month . Thankfully , there is 2 weeks tryout of Premium .
