![]() Fine-tune this setting while previewing audio to achieve maximum noise reduction with minimum artifacts. Controls the percentage of noise reduction in the output signal. The amount of noise reduction is always the same for all channels. Displays the selected channel in the graph. A logarithmic scale more closely resembles how people hear sound. To better distinguish them, click the menu button, and select options from the Show Noise Floor menu.įor finer control over low frequencies, select Logarithmic. Tip : The three elements of the noise floor can overlap in the graph. Threshold shows the amplitude below which noise reduction occurs. High shows the highest amplitude of detected noise at each frequency Low shows the lowest amplitude. Tip : To better focus on the noise floor, click the menu button to the upper right of the graph, and deselect Show Control Curve and Show Tooltip Over Graph. If you click the Reset button to flatten the control curve, the amount of noise reduction is based entirely on the noise print. For example, if you need noise reduction only in the higher frequencies, adjust the control curve downward to the right of the graph. The blue control curve sets the amount of noise reduction in different frequency ranges. If you regularly remove similar noise, however, a saved profile can greatly increase efficiency. However, you can apply noise prints only to identical sample types. Reduce the FFT Size or select a longer range of noise. ![]() Tip : If the selected range is too short, Capture Noise Print is disabled. Adobe Audition gathers statistical information about the background noise so it can remove it from the remainder of the waveform. Extracts a noise profile from a selected range, indicating only background noise. When recording in noisy environments, record a few seconds of representative background noise that can be used as a noise print later on. In the Editor panel, select the range from which you want to remove noise. To select noise in a specific frequency range, use the Marquee Selection tool. ![]() In the Waveform Editor, select a range that contains only noise and is at least half a second long. Threshold below which noise reduction occurs. Drag control points to vary reduction in different frequency ranges B. Quick links View all your plans Manage your plans. Now most of the noise should be removed from your audio. Remove all annoying background noise in one step. Get rid of unwanted sounds that are mixed into your main audio. Sometimes you will want to remove specific, isolated sounds. ![]()
