Does this come with an option that decreases background noise in audio? Like iMovie does
It depends what you are calling background noise.
In any case, there are numerous audio filters included, you just need to learn what they can do for your particular audio track.
Like a fan or something once the backround
If it’s a “constant” noise, it’s easy with the low pass filter.
normally i handle that through my sound cards settings…nice thing about that is now background noise is handled globally.
