Now, launch the application and hit Ctrl + Shift + I; to import an audio file. If it isn’t a Windows machine, you can navigate your way through Files Import Audio to import the audio file from which you want to remove the background noise. Re: how to remove background noise in my reverb kick!? Noahadvs wrote: Try not to use caps lock, it's annoying. The problem you're having is one that needs to be fixed in the mixing stage.

Between these two, you can handle pretty much any flavor of noise, from fairly simple hisses to more complex noises that cover different bands of the audio spectrum. There is even a noise learn function for quick and easy cleanup of audio material. User impressionsRedunoise has found plenty of avid fans among those that routinely work with outdoor recordings. Useful for reducing many types of background noise, the plug-in is also effective at separating sounds according to frequency range.Surprisingly, some users found Redunoise to be quite an effective EQ unit. With its many controls suited for creative EQing, Redunoise is way more than just your run-of-the-mill noise reduction plug-in. Bottom-lineRedunoise is a versatile noise reduction plug-in that has some surprising tricks up its sleeve, particularly in the realm of creative EQing.

Although it is free, it definitely measures up to even some of the best payware offerings available. Sound Recovery by BitsonicIf you have ever had to struggle with restoring signals from poorly recorded or severely degraded audio, might be exactly what you need, and for free. It’s designed specifically for repairing extremely low-quality audio.Sound Recovery fills a gap in the audio editing world that most EQs and noise reduction systems simply cannot fill.

With a unique set of features onboard, this plug-in should find value among audio restorers and even forensic professionals. Specs and useful featuresSound Recovery essentially recreates mid-frequency content from low-frequency harmonics. By adding subtle levels of harmonic distortion, this process makes audio clearer and more understandable, even with most of the mid-frequency content missing.Sound Recovery also has a multiband denoiser feature that makes it a very capable noise reduction solution.

Effective at reducing the noise from the low-mid and mid-high frequencies, this provides a much more subtle alternative to heavy-handed EQing that often thrashes the entire audio signal.Other features let you further restore audio with depth and precision. The “split freq” feature lets you define the most troublesome frequency range, while the dedicated “recovery” feature adds even more distortion for enhanced clarity. User impressionsSound Recovery is a fairly capable noise reduction plug-in. The low pass filter and the denoiser feature effectively reduce noise in a broad range of frequencies. But most users seem to use the plug-in for restoring lost audio content, which is hardly surprising given its capabilities in that area. Bottom-lineSound Recovery might not be your first choice if you need a comprehensive range of noise reduction features. But if your focus is on restoring the intelligibility of recorded audio, this plug-in is a must-have.

Noise Reduction by Christian Buddeis a spectral noise gate designed for removing unwanted noise from a variety of audio sources. By targeting specific frequency ranges, its spectral gate effectively filters out noise with a fair degree of customizability over attack and release times. Specs and useful featuresNoise Reduction goes beyond the capabilities of most spectral noise gate plug-ins by offering a good range of customization options. The soft knee control is fully adjustable over a very wide range, so you can avoid many of the sonic anomalies that other spectral noise gates impart to audio material.The plug-in comes with a few different options for FFT sizes, and you could even choose from many window functions.Noise Reduction sets itself apart from other plug-ins of its kind with its continuous and consistent characteristic. The plug-in’s various features let you clean up only the offending bands of noise without introducing artifacts that are often more bothersome than hissing and crackling.Noise elimination plug-ins generally have low CPU requirements, but Noise Reduction places especially low demands on computer resources. You could easily strap on as many instances as you need for your various tracks, and still have enough CPU power for your other plug-ins. User impressionsUsers found Noise Reduction to be effective at getting rid of noise from problematic soundboard recordings and audio transferred from tape.

For many users, the ability to identify the noise from a quiet section of audio is useful for treating the rest of the material. Bottom-lineLike all plug-ins of its kind, Noise Reduction is most effective when used sparingly at moderate settings. It won’t win any awards for precision and total control, but it will be enough to get the job done in most cases. FFT Tools by Smart Electronixturns to the graphics world for inspiration in dealing with unwanted noise in audio material. Based on the image-processing technique employed in graphics programs such as Adobe’s Photoshop, it utilizes spectral-based processing along with a slew of intriguing features.FFT Tools makes it possible to clear out the hash from specific audio frequency ranges while leaving the surrounding frequencies unscathed. The plug-in can also be used to warp sound in numerous interesting ways, many of which go beyond the capabilities of even dedicated sound-mangling plug-ins.

Specs and useful featuresOne of the most intriguing features of FFT Tools is “Warp”, which swaps high and low frequencies with each according to a defined frequency band. The results can be pretty wild, to say the least, although moderate settings can produce more musical results.Noise reduction functions are mostly handled by the “Levels” feature, which gives you a good degree of control over the spectral dynamics. This feature lets you liven up dull audio or remove background noise equally well.FFT Tools also comes with a “Kontrast” control for saturating specific bands of the frequency range.

If more robotic sounds are your thing, the aptly-named “Robotizer” should find plenty of use in your productions. User impressionsMost people seem to use FFT Tools for generating weird textures and alien-sounding sonic landscapes. Although it does a decent enough job at noise reduction, it seems better suited for creative sound design than cleaning up noisy material.

Bottom-lineFFT Tools probably won’t be the first thing that comes to mind if you need to clean up noisy audio. Although it will work as a noise reducer in a pinch, this plug-in is more useful as a tool for generating unusual sounds and textures.

WAVE EDITOR / RECORDER

The Noise Removal Tool can remove continuous background noises, such as hiss or electrical hum from a sample, repair clipped samples and remove clicks from samples. It's not designed to remove transient background noises such as a door slam or bird song. Any or all these denoise functions can be performed in a single pass. The modules are activated by the button in front of each section label. See a tutorial video here.

NOTE: The Denoiser, Declipper and Declicker have a button preceding the section titles, this activates the given function when selected. The Declipper and Declicker are deactivated in the screenshot above.

To Open the Noise Removal Tool

To open the Noise Removal Tool Left-click on the Clean up (denoise) button or use theTools > Spectral > Clean up (denoise) option.

Residual vs Removed Sound

Above the main display window.

• Output noise only - When selected the parts of the sample removed by the Denoiser tool (noise) are heard. Select this button when you need to fine-tune the Denoiser process Threshold andAmount settings (using the Preview function). Listen for settings that sound only like the noise to be removed. If you hear parts of the sound you want to retain in the noise output, then the settingsare too aggressive. When deselected the Preview & Accept buttons will deliver the processed (residual) sound according to the plugin settings.

Sample Display

The main display window shows a spectral view of the sample to be processed. This represents frequency on the horizontal axis and time on the vertical axis, while color represents intensity.

• Frequency scale - Zooms the frequency scale for more or less precise EQ curve editing or frequency inspection.

EQ Envelope

The (white) EQ envelope allows a +12 to -24 dB EQ curve to be applied to the selected sample. Time is represented on the vertical axis and Frequency on the horizontal axis.Apply EQ in addition to the other noise reduction functions to fine-tune the result.

To edit the EQ curve: Right-click in the 'Envelope Editor Window' to add points, and Left-click to move points and tension markers. Right-click points to open a context menu thatallows you to delete points or change the curve type. The default mid-line is 'no change'. Boost/Cut values appear in the FL Studio Hint Bar as the nodes are moved.

If you need a dedicated equalizer use the Equalize tool.

• Reset - Resets the EQ envelope to the default state.
• Envelope options (small right facing arrow under the EQ display window).
  • Open state file / Save state file - Opens/saves envelope states. Several different pre-defined state files are available.
  • Copy state / Paste state - Use this to copy and paste envelopes, usually between instances of the EQ editor across open Edisons.
  • Undo - Undoes the last envelope edit.
  • Undo history / Last reset - Shows the editing history since the last reset.
  • Flip vertically - Inverts the current envelope.
  • Scale levels - Opens the Scale Level tool.
  • Normalize levels - Scales the envelope so the highest and/or lowest levels reach +/- 100%.
  • Decimate points - Opens a simple tool that allows manipulation of the number of control points in the envelope (useful in conjunction with Analyze audio file).
  • Filter - Opens the Envelope Filter tool (useful in conjunction with Analyze audio file).
  • Smooth up - Opens the Smooth Up tool that allows smoothing of the envelope shape (useful in conjunction with Analyze audio file).
  • Smooth up abrupt changes - Quick removal of 'spikey' or sudden changes in the envelope.
  • Turn all points smooth - Preset filter to quickly filter the envelope.
  • Create sequence - Opens the Envelope Sequencer tool.
  • Analyze audio file - Open, analyze and replicate the volume envelope of an input sound file. Drag and drop audio files directly on the Envelope editor for automatic analysis.

Denoiser

To activate ensure the Denoiser button is selected. The Denoiser is designed to reduce or remove constant background noises in recordings. This background noise can include tape hiss, microphone hum, power mains buzz, camera motor noise, air-conditioning rumble and any other type of noise that doesn't change in level or frequency significantly throughout the recording. If you need to remove door slams, bird song or any similar transient and variable sound. This is not the tool you are looking for.

• Threshold - Controls the separation of noise and desirable signal levels. Higher threshold settings reduce more noise, but also may suppress low-level desirable components of the signal (select the Output noise only switch to hear the sound being removed).A lower threshold preserves low-level signal details, but can result in noise being modulated by the retained sounds. A good default is 0 dB.
• Amount - Controls the level of noise suppression in decibels. Strong suppression can degrade low-level residual audio, so it's recommended to apply only as much suppression as needed to reduce thetarget noise to the level that is barely noticeable (click the Preview button to audition various settings prior to applying the noise reduction). Remember, if the sound is to be used in a mix, then it is likelythat less suppression will be needed to render the noise inaudible.

Using the Denoiser:

1. Noise profile - The Denoiser needs to hear an example of the background noise, preferably in isolation from other sounds, so that it can generate an accurate 'noise profile'. From main Edison samplewindow, select a section of the sample that contains only noise (if possible). Examine the start and end of the sample, where noises are usually exposed. Alternatively, you may need to select regions in the samplewhere there are pauses in the desirable sound (breaks in speech or singing for example). If a 'noise-only' region can't be found, select a quiet section of the sample where the noise is at its most audible. After selectingthe longest section of noise that you can find, Right-click the Clean up (denoise) button to create the noise profile. If the Noise Removal Tool is open, click the Acquire noise profile button to select thenoise sample.
2. Select the region to be processed - Prior to returning to the Denoiser interface, make sure that the region you want to denoise is selected in the main Edison sample window (the Denoiser will retain thenoise profile so it is OK to close the Denoiser to select the region to be processed). If no region is selected the whole sample will be processed, this is usually the desired outcome as processing small sections of asample can lead to audible tonal changes at the boundaries of the processed region.
3. Preview the settings - Open the Denoiser Tool and preview the default settings by clicking on the Preview button. Note the noise profile will appear in the Denoiser as a green frequency curve(see the screenshot above).
4. Fine tune the controls - Sometimes you may hear 'underwater' artifacts of the noise reduction process, if so you should continue to adjust first the Threshold and then the Amountsettings. You should apply only enough reduction (Amount) to make the noise barely or not noticeable in the context for which the sound is to be used. Excessive amount settings are guaranteed to cause audibleartifacts. It is often useful to select the Output noise only button to more clearly hear the parts of the sample being removed. Ideally only noise will be heard.
5. Accept the result - Once you are satisfied with the settings.
6. Practice makes perfect - If you would like to experiment, the sound 'Maximus NoiseGate Tutorial 44kHz.wav' is avocal mixed with some power-supply hum, exposed at the end of the sample. To download the file you will need to create a logon at freesound.The freesound project is an initiative of the Music Technology Group of Pompeu Fabra University to build a library of Creative Commons licensed sounds.

Declipper

To activate ensure the Declipper button is selected. The Declipper can repair digital and analog clipping artifacts that result when A/D converters are overloaded or magnetic tape is over-saturated.The Declipper can be extremely useful for saving recordings that can't be re-recorded such as live concerts, interviews or one-off audio events.

• Threshold - Selects the clipping level used for detection of clipped peaks. The ideal setting is a level just below the actual level of clipping, you can examine the waveform in the main Edison window andinspect the clip level by hovering the mouse over the clipped waveform.

NOTE: The Declipper re-creates peaks above the clipped level and will therefore reduce the overall volume of the recording to provide headroom for this process. In light of this, declipping usually needs to be applied to the entirerecording in order to avoid a sudden drop in volume in the processed region.

Declicker

To activate ensure the Declicker button is selected. The Declicker is useful for restoring for old vinyl and other recordings that cause clicks, pops and/or crackles. The Declicker can also remove a varietyof short noises from other sources, including lip clicks and 'smacking' on vocals, some clicks caused by digital errors or electrical interference. The Declicker works best onclick-transients of 10 ms or less.

• Sensitivity - Controls the aggressiveness of the click detection algorithm. Low values of this parameter will remove fewer clicks, while higher values may treat musical transients as clicks, resulting in distortion.

Accept button

• Accept - Processes and pastes (replaces) the original selection.
