To undo the last filter and try a more precise approach, go to Edit > Undo Adaptive Noise Reduction, as shown in Figure 17 (below).įigure 17. removing background noise to adding reverb and other sound effects. But if it's not adequate in the project you're working on, there's something else you can try. audio, with popular ones including Adobe Audition, Audacity, and GarageBand. For example, noise produced by a turntable motor or an action camera. In most instances, I would probably say that's okay and move onto the next edit. Reduce Rumble: Reduce the rumble noise, a very low-frequency noise, that ranges below the 80-Hz range. Most of the bushy lines are gone, which means we've removed most of the gain noise. There's still a bit of noise, but it's vastly reduced.įigure 16. How to Eliminate Background Noise in Adobe Audition A Powerful DAW Using Built-in Tools Using 3rd Party Plugins Avoid the Issues by using High-Quality Music. You can see in Figure 16 (below) that most of the bushy lines between the waveforms are gone. I recommend starting with Light Noise Reduction ( Figure 15, below).įigure 15. Choosing the automated Noise Reduction approach Double-click in the waveform to select the entire waveform, and then choose Effects > Noise Reduction Restoration > Adaptive Noise Reduction, as shown in Figure 14 (below).įigure 14. As with pops and clicks, the first thing you want to try is the automated approach. Bushiness in quiet regions of the waveform (such as the area highlighted here) means gain noise introduced when we boosted the audio. In this clip we can hear background noise that we just couldn't hear before.įigure 13. If you zero in on quiet (or near-silent) regions of the waveform and it looks bushy (see Figure 13, below), this bushiness typically means you're going to have some audible noise that resulted from the boost you gave to your audio when you normalized to -.01 dB. Dealing with Gain Noiseīut we've got one problem and that problem is the gain noise I talked about earlier. You take a Noise Print from that, then remove it from the whole clip bear in mind that you never. Clicks are gone, and overall volume looks good. You’re going to find that removing the Noise Floor will get you part of the way, removing the ambient noise all you need to make sure of is that you have a point in your production where the only sounds there are the background sounds. Increasing the volume of the clip by normalizing to -0.1 dBĪfter applying this filter, as you can see in Figure 12 (below), the audio file looks pretty healthy.įigure 12. This boosts the entire audio file so that the loudest region is just under 0 dB, which is as loud as you can get without introducing distortion into the audio file.įigure 11. We can fix that in the Favorites menu by choosing Favorites > Normalize to -0.1 dB ( Figure 11, below). Now we've taken care of all the pops and clicks, but as you can see in the waveform, the audio is way too low.
