I recorded an audio track with Audacity. With the sound being done, I used the noise reducer to take out of the parasit noise of the microphone with a reduction setting of 12 throughout the track.
The result being relatively good but not perfect in my opinion (my new microphone is noisier than the old one), I therefore decided to redo a noise reduction passage on the “silences” (always a little noisy) between the parts. of voice. So I used the noise reducer again with increased reduction (15), of course selecting ONLY those parts to correct. So normal procedure: I get a sample of the part of the track to correct then I select the whole of the part to be processed
And there, worries! the noise reducer also modifies the voice parts on either side of the “silence” (I can see it in the voice curve which changes and loses frequencies. The voice parts therefore had in the end 2 treatments of reduction, which affects the quality
Do you know the origin of this problem? Bug?
Thank you in advance for your answers
