Higher bit depths provide more dynamic range and reduce distortion, though they increase file size and processing time. To determine the proper setting for common output types, see Understanding bit depth. Integer settings clip audio that extends beyond the amplitude range for a given bit depth. Floating Point settings require slightly more storage space, but retain much greater dynamic range.

Choose bit Floating Point if you want to repeatedly process the file and discard minimal amplitude data. See Viewing and editing XMP metadata. Byte Order available only for bit files. Specifies the numerical sequence for bytes of data. Monkey’s Audio compresses files to roughly half their original size, using a lossless algorithm that retains sonic fidelity.

Determines the tradeoff between processing speed and file size. Fast processing produces larger file sizes, and vice versa. Channel Mode. Adjusts the tradeoff between file size and audio quality. Higher settings increase size and quality; lower settings reduce size and quality. For information about Advanced options, position the mouse over them until a tool tip appears.

Choose Constant to apply a consistent bitrate or Variable to change the bitrate based on audio content. Bitrate for constant bitrates or Quality for variable. Avoid compressing the same audio to mp3 more than once. Opening and resaving an mp3 file causes it to be recompressed, so any artifacts from the compressing process become more pronounced.

The nonstandard Note : To ensure compatibility with a wide range of applications, choose the RF64 format for files greater than 4GB. FLAC format uniquely is both compressed reducing file size and lossless retaining full audio fidelity. The Default Byte Order automatically applies the default for your system processor and is typically the best option.

Determines the tradeoff between file size and audio quality. Higher settings produce larger files, but better quality. Legal Notices Online Privacy Policy. Buy now. User Guide Cancel. Save audio files. In the Waveform Editor, do one of the following:. Specify a filename and location, and choose a file format. Set the following options:. Sample Type.

All clips and tracks become mono. Phase cancelation from poorly placed stereo microphones or misaligned tape machines. See Automatic Phase Correction effect. The real-time restoration effects above, which are available in both the Waveform and Multitrack editors, quickly address common audio problems. For unusually noisy audio, however, consider using offline, process effects unique to the Waveform Editor , such as Hiss Reduction and Noise Reduction. Watch the Audio restoration techniques video to learn best practices for fixing audio in Audition using the Amplitude Statistics panel, spectral frequency display, adaptive noise reduction, Diagnostics panel, and DeClipper and DeHummer effects.

This effect can remove a combination of noise, including tape hiss, microphone background noise, power-line hum, or any noise that is constant throughout a waveform.

The proper amount of noise reduction depends upon the type of background noise and the acceptable loss in quality for the remaining signal. 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.
