Generally, you can find areas in the beginning or end of the clip, or during pauses, that have a thick line around the middle of the waveform, but no spikes.įigure 75a. Audio corrected with a noise gate filter often sounds artificial, because the filter removes ambient noise the listener hears in other regions of the audio file.Ĭlick and drag your pointer to select a region that contains only the background noise (Figure 75a). In contrast, a noise gate filter simply mutes regions in the file that don't meet a specified threshold and doesn't touch the other regions. Noise reduction removes the noise identified in the Noise Reduction Profile from the entire audio file. Then, you preview and adjust the controls to fine-tune the application of the filter. This creates what Audition calls the Noise Reduction Profile. To do so, select a region in the waveform that contains just the noise to remove. As you might expect, Audition can't tell a "good" noise from a "bad" noise on its own, so first you have to tell the program what the unwanted noise is and isolate it. While you can edit audio using computer speakers for some operations, noise reduction definitely calls for your best set of headphones.Īpplying the filter is a three-step process. Noise Reduction can be a very subtle effect, especially when you're hunting for audio distortion. It does not work on irregular noises like applause, horns honking, or people laughing. Noise Reduction removes consistent noises from audio files like the hum of an air conditioner, or similar noise produced by using sub-par microphones.
