As I have quite loud fan noises and am able to remove them completely with close to non quality loss in my voice with audacity and the process hardly taking any time at all.
I was wondering. Has it been done before or can someone make it to be possible to record the microphone and apply noise reduction in real time to your microphone and stream that audio to virtual cable driver?
Best noise reduction results I have found by using “Noise reduction (db): 10” and “Sensitivity: 5” and “Frequency smoothing (bands): 0” and “Noise: Reduce”
First I get the Noise profile. Then I apply the noise reduction to where I took the noise profile and where I want the noise to be gone. Then I get new noise profile of the reduced sample and repeat that “reducing process” about 6 times.
In the end I get astonishingly good results compared to just using higher “Noise reduction (db)” or changing any other parameters.
I don’t see a way to attach a file so I cannot give my testing file where I just give example of the reduced noise and with out reduced noise.
While testing “Sensitivity” I found that going below 5 gives artifacts that can be removed by adding “Frequency smoothing (bands)” and it removed bass from the audio. And going above 5 started adding more bass to the recording and reducing other sounds.
I also never thought that my very small room ever had any echo before… But now that I was able to near perfectly (My voice quality does suffer compared to the original recording but that is expected and acceptable as I don’t have a proper mic to begin with) get rid of the background sounds. I got frustrated by the echo sound I have in here. But that is getting away of topic.
Anyone know the code to know is this possible to do in real time or not?
As there is quite many millions of people who would love to get this type of noise reduction in real time so it doesn’t need to be done seperatly.
As I tried to hint before (but I know someone will reply by saying stupid things) this IS NOT processor demanding task. Unless your computer is from the year 98.
