In Audition, you’ll have to first capture a noise print before you can use the noise reduction. There are a lot of other effects, like hiss remover, that you can use to mitigate different frequencies, and adaptive noise reduction, which doesn’t need a noise print. You can perform noise reduction in a lot of different ways, but one of the best ones uses something called a noise print to selectively cut out noise, and is useful for all kinds of noise. Looking closer, these lines of noise stretch across all of the audio.Īfter noise reduction, there’s still noise, but there’s much less of it.īecause it cuts out those frequencies, this does distort the audio a little bit, which is where having a less noisy microphone comes in handy, as you can only do this so much without it sounding like you’re talking through a tin can. Before noise reduction, you can see here at the end of the audio (while I wasn’t talking) there’s still a lot of data. It shows levels of noise at each frequency, over time. The spectral frequency display in Audition is useful for visualizing noise.
