You can fix a wide array of audio problems by combining two powerful features. First, use Spectral Display to visually identify and select ranges of noise or individual artifacts. See Select spectral ranges and Select artifacts and repair them automatically. Then, use either Diagnostic or Noise Reduction effects to fix problems like the following:. Crackle from wireless microphones or old vinyl records.

See Automatic Click Remover effect. Background noise like wind rumble, tape hiss, or power-line hum. 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.

Given that it comes without a price tag, we can forgive the limitations. Audacity Price: Free. Best free editor for simple, fast edits. It’s a capable all-arounder with a clean and minimal interface that sets it apart from the comparatively cluttered Audacity.

Add markers to your files, make edits to specific channels, and manipulate the metadata before exporting your recording. In addition to the basic trimming and clipboard operations, ocenaudio also includes a number of effects and support for VST plugins and AU plugins on a Mac.

These include simple noise reduction operations, filters, a band equalizer, plus time and pitch adjustment. Highlight audio to get quick access to functions like cut, copy, and delete, and to see exact timecodes. It’s a simple editor, but it’s perfect for users who find Audacity’s interface overwhelming and clunky.

Thanks to some clever memory management, ocenaudio is great for editing large files without performance taking a hit—something that’s rare for free editors. If you don’t need multi-track support or all of the effects and plugins included in Audacity, ocenaudio is the editor for you. It’s also considerably better looking.

Best audio editor for creating and deploying effect chains. Acoustica Standard Edition offers more than your average free audio editor in a package that won’t break the bank. It’s a high-resolution audio editor, with support for 32 bit audio and sample rates of up to kHz. You can use Acoustica for single-track waveform editing or multi-track mixing where you can loop, stretch, and fade clips on a timeline.

Basic effects include a limiter, an equalizer, and a suite of audio restoration tools for removing hiss, pop, and hum from recordings. Each of these can be chained together, saved, and deployed with a click across multiple sessions and files.

Acoustica is also compliant with common broadcast standards, making it easy for working with video soundtracks. Acoustica’s neat row of useful icons, dark color scheme, and tab-based interface for working on multiple files should prevent you from feeling overwhelmed by the extensive feature set.

If you find yourself craving more “professional” features, the Premium Edition of Acoustica offers even better audio restoration tools, multi-channel 7. Best audio editor for one-click audio repair and batch operations. A self-described “swiss army knife of sound editing,” Amadeus Pro is a multi-track audio editor for Mac with a focus on user-friendliness. An attractive interface displays only a handful of icons for the most basic operations, including playback controls, the record button, and a few multi-track functions like adding new tracks or splitting stereo recordings into individual tracks.

Most other functions are triggered via the menu bar or a keyboard shortcut. In addition to the basic editing operations, Amadeus includes a batch processing module for applying effects, writing metadata to, and converting multiple audio files via a simple drag-and-drop interface. Apply effects like RIAA equalization and amplification, trim silence, and suppress white noise. The app also allows you to apply plugins in AU format to a selection of files in a click. Amadeus Pro includes a tool called Repair Center, which scans your file for imperfections and attempts to repair them for you.

You can listen to the repaired segment before applying it to your recording. The nature of the Repair Center tool makes it particularly easy: It’s a bit like using a spell checker that scans through your document and suggests improvements.

There’s also a built-in burning tool for committing your recordings to CD, provided your Mac has an optical drive. Best audio editor for quick and simple edits on a Mac.

For Mac users, Fission feels like home. It’s a pure Mac app, built from the ground up with macOS in mind. This much is evident from the most basic of functions, which closely mimic Apple’s desktop OS. Fission lacks many of the effects found in its rivals. You can apply fades, normalize audio, or amplify sections, but there are no equalizers, noise reduction is absent, and plugins aren’t supported. Instead, the emphasis is on lossless waveform editing, with the overall quality of your audio being Fission’s main focus.

There’s no multi-track editing or recording of multiple inputs—this is a simple and streamlined waveform editor. The editor includes a batch processor for converting files from one format to another.

Export your audio as chapterized MP3 or AAC files by marking regions as chapters in Fission, then exporting under the File menu or export in iPhone ringtone format. It’s a simple editor, at a reasonable price point, and it’s perfect if you don’t want to get bogged down by features you’ll never use.

Best audio editor for journalists and podcasters. Hindenburg Journalist is a multi-track audio editor aimed at professionals who work with the spoken word. You can either record directly into the app or arrange files you’ve already recorded elsewhere. It’s perfect for cutting together interviews or producing podcasts since it handles some of the more technical aspects of production for you.

The app’s standout feature is its ability to handle levels for you. As soon as you’re done recording or importing a waveform, watch Hindenburg Journalist automatically increase or decrease the volume of the track to comply with modern loudness standards. You can then use the built-in profiler, an automated equalizer for enhancing voice tracks, to optimize your audio for publishing. Hindenburg makes it easy to create and arrange projects on a timeline.

You can add markers or separate audio by chapter while recording, so you don’t lose track of important sound bites.

The app’s clipboard function provides four groups into which you can divide your sound bites, music, ambiance, and other audio clips, with the ability to paste the top clip with a custom shortcut. Best audio editor for Windows users on a budget. Despite the affordable price tag, Audio Studio 12 is a powerful tool for editing, mastering, and exporting audio to a variety of formats.

It’s not a multi-track editor, instead focusing on a single stereo file or recording at a time. Common tasks that the app handles confidently include cutting up files, merging recordings, cleaning up audio, and applying effects.

Audio Studio 12 comes with iZotope Ozone Elements, a dedicated mastering processor which runs alongside the main app as a plugin. Ozone includes professionally-designed presets to make your recordings sound richer and punchier with minimal effort. Video integration is one of Audio Studio 12’s strong points. You can open a video file and see the individual frames on the timeline while making your edits.

When you’ve improved your soundtrack, it’s easy to merge—or “remux”—that audio file back into the video, without having to take the time to re-render the whole thing. Best audio editor for web-based audio editing. Editing audio in a browser isn’t for everyone.

This is incredibly important when dealing with multiple microphone sources, to eliminate an unwanted channel, or to isolate dialogue from a 5.

In addition, you can also use “adaptive” tracks for non standard formats with support for up to 24 channels per clip or track. No matter how many sources you sync to your clips, they will playback seamlessly and can be edited to a single multi channel track or separate mono tracks. Track format can be changed by right clicking on the track header.

Clip format can be changed by right clicking on the clip and changing clip attributes. You can use the index to locate clips, quickly change track states, and even create spotting lists with markers. In list view, the markers index shows each timeline marker as an icon, along with notes and description columns for creating a detailed spotting list.

The track index lets you quickly select or toggle track states such as lock, arm, solo and mute with a swipe of the mouse. You can also rename tracks, show or hide visibility in the timeline and mixer, and even drag to reorder tracks!

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. Choose a high setting to increase frequency resolution; choose a low setting to increase time resolution.

High settings work well for artifacts of long duration like squeaks or power-line hum , while low settings better address transient artifacts like clicks and pops.

Watch the video Remove noise from audio files with Audition to see how you can reduce noise and remove unwanted sounds from your audio.

You can correct a large area of audio or a single click or pop. This effect provides the same options as the DeClicker effect, which lets you choose which detected clicks to address see DeClicker options. However, because the Automatic Click Remover operates in real time, you can combine it with other effects in the Effects Rack and apply it in the Multitrack Editor. The Automatic Click Remover effect also applies multiple scan and repair passes automatically; to achieve the same level of click reduction with the DeClicker , you must manually apply it multiple times.

Determines sensitivity to noise.
