Audacity Forum

I select a position in the audio track that I want to generate noise. Then I generate, say 600ms of noise. I see the noise inserted in the selected track, but in the below track, a portion of the audio near the same timestamp I generated noise for the top track, is removed!

When I use generate noise, it sometimes removes audio from the other track I am working with. I click a spot where I want to generate noise, and I see the top track grow because of the added noise... ...but then I also see the bottom track shrink because the effect removed something from it??? :shoc...
