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. Clicks are gone, and overall volume looks good. 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.
