Typically, the further you drag to the right, the more voice you’ll hear in the removed audio. While previewing with Output Noise Only, drag the Noise Reduction slider to the left and right. Or, make another shorter selection directly in the Audition waveform to use during the preview. Click the Select Entire File first to hear the entire file, rather than just the noise you selected in the previous step. So my goal is to remove as much background noise as possible without introducing distortion or causing a mismatch between what the viewers are hearing and what they’re seeing.Īfter capturing the noise print, my process is to enable the Output Noise Only toggle (as shown), which plays the audio being removed by the filter, not the residual. For example, my video was shot in a large ballroom, where some measure of ambient sound is expected. Your goal isn’t to remove every last bit of background noise from the audio, particularly if that causes distortion, or even if it causes a mismatch between the audio and video. In addition, consider the purpose of the operation. To state the obvious, you will work most effectively in a quiet room with headphones. To configure these settings, you have some outstanding preview tools, which is the special sauce that Audition delivers that Premiere Pro doesn’t. I won’t go into the Advanced controls accessed via the Advanced option on the bottom, leaving only two controls to adjust: Noise Reduction, which defines the noise you’re going to remove and Reduce By, which controls the decibel reduction to that noise. Customizing the Audition Noise Reduction filter ![]() When you’ve identified the ideal sample, load the dialog shown in Figure 4 (below) by clicking Effects > Noise Reduction/Restoration > Noise Reduction (process).įigure 4. When you select a region, preview to make sure that you’re capturing only the background noise to be removed, and not other sounds. You drag and select a region on the waveform containing only noise and then choose Effects > Noise Reduction/Restoration > Capture Noise Print. I show how to identify the noise in Figure 3. Noise reduction in Audition is a two-step process: First, you identify the noise, then you configure the noise reduction filter. As you’ll see, Audition has a fabulous toolset for finding this sweet spot. So, when removing noise, you’re attempting to find the optimal balance between noise reduction and distortion creation. If you remove too much noise, you distort the audio, which may be more noticeable than the background noise. Here’s why: At a high level, think of noise reduction as a continuum between noise and distortion. On the other hand, if you’re seeking to lovingly optimize the quality of a single clip, you’ll probably find Audition’s Noise Reduction Process more effective. For perspective, if you’re working with dozens of audio files and are in a hurry, you may prefer to work with the Reduce Noise Function in Premiere Pro’s Essential Sound panel, which deploys Premiere Pro’s Adaptive Noise Reduction filter. More information on how to meet these requirements can be found below and in our Video Lessons & Resources, and many of the terms used here can be found in our Audio Terminology Glossary.Let’s start by removing the background noise. Some examples are but not limited to: ! # $ % & ' ^ ` ~ +.When naming files, please use only standard US alphabetical/numeric characters.be a 192kbps or higher MP3, Constant Bit Rate (CBR) at 44.1 kHz.measure between -23dB and -18dB RMS and have -3dB peak values and a maximum -60dB noise floor.have room tone at the beginning and end and be free of extraneous sounds.have a running time no longer than 120 minutes.contain only one chapter/section per file, with the section header read aloud.include a retail audio sample that is between one and five minutes long. ![]() ![]() be comprised of all mono or all stereo files.be consistent in overall sound and formatting.The following requirements help ensure customers get a great listen.
