To achieve the best results with the Noise Reduction effect, apply it to audio with no DC offset. With a DC offset, this effect may introduce clicks in quiet passages. Drag control points to vary reduction in different frequency ranges B. Low amplitude noise.
High amplitude noise D. Threshold below which noise reduction occurs. In the Waveform Editor , select a range that contains only noise and is at least half a second long.
To select noise in a specific frequency range, use the Marquee Selection tool. See Select spectral ranges. In the Editor panel, select the range from which you want to remove noise. When recording in noisy environments, record a few seconds of representative background noise that can be used as a noise print later on. Capture Noise Print.
Extracts a noise profile from a selected range, indicating only background noise. Adobe Audition gathers statistical information about the background noise so it can remove it from the remainder of the waveform. Tip : If the selected range is too short, Capture Noise Print is disabled.
Reduce the FFT Size or select a longer range of noise. Save the Current Noise Print. Saves the noise print as an. Load a Noise Print from Disk. However, you can apply noise prints only to identical sample types. If you regularly remove similar noise, however, a saved profile can greatly increase efficiency.
The blue control curve sets the amount of noise reduction in different frequency ranges. For example, if you need noise reduction only in the higher frequencies, adjust the control curve downward to the right of the graph. If you click the Reset button to flatten the control curve, the amount of noise reduction is based entirely on the noise print.
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. High shows the highest amplitude of detected noise at each frequency; Low shows the lowest amplitude.
Threshold shows the amplitude below which noise reduction occurs. Tip : The three elements of the noise floor can overlap in the graph.
To better distinguish them, click the menu button , and select options from the Show Noise Floor menu. For finer control over low frequencies, select Logarithmic. A logarithmic scale more closely resembles how people hear sound. Displays the selected channel in the graph. The amount of noise reduction is always the same for all channels. Select Entire File.
Noise Reduction. Controls the percentage of noise reduction in the output signal. Fine-tune this setting while previewing audio to achieve maximum noise reduction with minimum artifacts. Excessively high noise reduction levels can sometimes cause audio to sound flanged or out-of-phase.
Determines the amplitude reduction of detected noise. Values between 6 and 30 dB work well. To reduce bubbly artifacts, enter lower values. Output Noise Only. Advanced settings. Spectral Decay Rate. Specifies the percentage of frequencies processed when audio falls below the noise floor.
Takes into account the variance of the noise signal in each frequency band. Bands that vary greatly when analyzed such as white noise will be smoothed differently than constant bands like Hz hum.
In general, increasing the smoothing amount up to 2 or so reduces burbly background artifacts at the expense of raising the overall background broadband noise level. Precision Factor. Controls changes in amplitude. Values of work best, and odd numbers are ideal for symmetrical processing. With values of 3 or less, the Fast Fourier transform is performed in giant blocks, and between them drops or spikes in volume can occur.
Values beyond 10 cause no noticeable change in quality, but they increase processing time. Transition Width. Determines the amplitude range between noise and desirable audio. For example, a width of zero applies a sharp, noise gate to each frequency band. Audio just above the threshold remains; audio just below is truncated to silence.
Alternatively, you can specify a range over which the audio fades to silence based upon the input level. Determines how many individual frequency bands are analyzed. This option causes the most drastic changes in quality.
The noise in each frequency band is treated separately, so with more bands, noise is removed with finer frequency detail. Good settings range from to Fast Fourier Transform size determines the tradeoff between frequency- and time-accuracy. Higher FFT sizes might cause swooshing or reverberant artifacts, but they very accurately remove noise frequencies. Lower FFT sizes result in better time response less swooshing before cymbal hits, for example , but they can produce poorer frequency resolution, creating hollow or flanged sounds.
Noise Print Snapshots. Determines how many snapshots of noise to include in the captured profile. A value of is optimal for producing accurate data.
Very small values greatly affect the quality of the various noise reduction levels. With more snapshots, a noise reduction level of will likely cut out more noise, but also cut out more original signal.
However, a low noise reduction level with more snapshots will also cut out more noise, but likely retain the intended signal. This effect analyzes a selected portion of the recording, and builds a sound model, which is used to find and remove the sound. The generated model can also be modified using parameters that indicate its complexity. A high complexity sound model requires more refinement passes to process the recording, but provides more accurate results. You can also save the sound model for later use.
Several common presets are also included to remove some common noise sounds, such as sirens and ringing mobile phones. Learn Sound Model. Uses the selected waveform to learn the sound model. Select an area on the waveform that only contains the sound to remove, and then press Learn Sound Model. You can also save and load sound models on disc. Sound Model Complexity.
Indicates the complexity of the Sound Model. The more complex or mixed the sound is, the better results you'll get with a higher complexity setting, though the longer it will take to calculate. Settings range from 1 to Sound Refinement Passes. Defines the number of refinement passes to make to remove the sound patterns indicated in the sound model.
Higher number of passes require longer processing time, but offer more accurate results. Content Complexity. Indicates the complexity of the signal. Settings range from 5 to Content Refinement Passes. Specifies the number of passes to make on the content to remove the sounds that match the sound model. A higher number of passes require more processing time, but generally provide more accurate results.
Enhanced Supression. This increases the aggressiveness of the sound removal algorithm, and can be modified on the Strength value. A higher value will remove more of the sound model from mixed signals, which can result in greater loss of desired signal, while a lower value will leave more of the overlapping signal and therefore, more of the noise may be audible though less than the original recording. Enhance for Speech.
Specifies that the audio includes speech and is careful in removing audio patterns that closely resemble speech. The end result makes sure that speech is not removed, while removing noise. Watch the video Sound removal and noise reduction strategies to see how you can reduce noise and remove unwanted sounds from your audio.
Because this effect operates in real time, you can combine it with other effects in the Effects Rack and apply it in the Multitrack Editor. By contrast, the standard Noise Reduction effect is available only as an offline process in the Waveform Editor. That effect, however, is sometimes more effective at removing constant noise, such as hiss or hum.
For best results, apply Adaptive Noise Reduction to selections that begin with noise followed by desirable audio. The effect identifies noise based on the first few seconds of audio.
This effect requires significant processing. Reduce Noise By. Determines the level of noise reduction. To reduce bubbly background effects, enter lower values. Fine Tune Noise Floor. Signal Threshold. Manually adjusts the threshold of desirable audio above or below the automatically calculated threshold. Determines how quickly noise processing drops by 60 decibels. Values that are too short create bubbly sounds; values that are too long create a reverb effect. Broadband Preservation. Retains desirable audio in specified frequency bands between found artifacts.
A setting of Hz, for example, ensures that no audio is removed Hz above or below found artifacts. Lower settings remove more noise but may introduce audible processing. It has a beginner-friendly UI that appeals to a lot of people, while also having multiple templates and presets to speed up your process. Audition offers a handful of ways to remove background noise. It features light, non-damaging tools like equalizer, as well as more hardcore background noise removal tools.
Sometimes, the background noise in your audio is a constant hiss and presents as such. This is what is usually described as a noise floor. Adobe Audition offers multiple equalizers to choose from, and you should play around with them a little to find which ones you prefer to reduce noise with.
Audition lets you choose between one octave, one-half octave, and one-third octave equalizer settings. EQ is good for low-intensity noise, but not very useful for more serious stuff. Frequency analysis is a cool tool that helps you find and remove background noise in Adobe Audition. Unlike with Equalizer where you manually find the problematic frequency band, the Frequency Analysis tool helps you localize the troublesome frequencies.
The Spectral Frequency Display is another cool way you can localize and remove any additional noise you may have picked up while you shoot.
The Spectral Frequency Display is a representation of the amplitude statistics of specific frequencies as they change over time. This feature helps you highlight any sound that is obviously contradictory to your work, e. This tool has loose noise and true sound differentiation, so use with caution and experiment with the sliders for best results.
Sometimes what we hear as background noise in Adobe Audition may be noise from distortion caused by your audio source going into overdrive. Check out our article where we go into detail on audio distortion and How to Fix Distorted Audio. Another way to get rid of unwanted noise in Adobe Audition is by using the Adaptive Noise Reduction tool.
The Adaptive Noise Reduction Effect is particularly useful for wind noise and ambient noise. It can pick up small sounds like a random gust of wind. Adaptive noise reduction is also good at isolating excessive bass. A more difficult scenario is when you need to remove a noise that occurs at the same time in the clip as sound that you want to keep in your audio file.
In this video, you will learn how to use the Paintbrush selection tool to select the unwanted noise, create another noise profile, and again use the Sound Remover effect to remove a bell that rings at the same time that someone is talking. You will also learn how to remove ambient noise by using the marquee selection tool to select the background noise, capturing a noise print, and using the Noise Reduction effect to remove it.
Sometimes you will have video or audio files where the background noise is uneven or inconsistent. You could use the technique you learned in the previous video to remove each piece of inconsistent noise in several separate steps.
However, Audition has a feature that will allow you to remove all the inconsistent noise in one step. In this video, you will use the Adaptive Noise Reduction effect to analyze the audio in the clip and adapt to changes in the noise over time. This will allow you to remove all the noise in one step.
