Almost all users working with professional and semi-professional audio editors when recording vocals (voices) or live instruments at home, where the necessary sound insulation is not provided for the premises, are faced with the problem of removing extraneous noise that may overlap the recorded material. Next, we will consider how to remove noise in Adobe Audition using various tools of the program itself and with modeling different situations in which such actions may be required. It is immediately worth noting that the application in question is taken solely as an example, since for similar programs like Cool Edit Pro, which is the predecessor of the Audition software package, or for editors like Sound Forge and similar ones used for editing noise, the actions are almost identical. The difference can only be in the names of the built-in tools.
How to remove noise in Adobe Audition: basic technique
In principle, the program itself has at least five tools for automatic or manual noise reduction. However, the most preferred tool that allows you to remove noise in Adobe Audition 3.0, as well as in any other modifications (SC, CC, etc.), most experts call the elimination of interference based on their pre-recorded sample. But foreseeing absolutely everything will not work, so sometimes you can use the standard predefined parameters, the use of which allows you to get rid of standard noise in the mains or something like that.
How to remove microphone noise in Adobe Audition or automatically when recording a part of a live instrument?
So, first we’ll try to use the simplest method. After the material has been recorded before it has been processed by additional plug-ins, it is worth using the Adaptive Noise Reduction tool, which can be called up in the general noise reduction section from the effects menu. For the selected fragment or for the entire track, you can remove noise in Adobe Audition CC or any other version of the application by selecting the available templates. The use of heavy interference cancellation (Heavy) after a preliminary analysis will remove very loud noises, while reducing the quality of the recorded material.
In the best case, it is better to use the Light template, although you can edit the installation of the necessary parameters yourself by moving the sliders to the desired positions. The only drawback of this method is that you won’t be able to listen in real time, and you will have to save the file to your hard drive.
Noise reduction in manual mode based on a fragment of interference
Now a few words about how to remove noise in Adobe Audition using a preliminary noise analyzer. To do this, you can select a tool called Noise Reduction (process).
First you need to click the “Capture Noise Print” button with the selection of the current file (Select Entire File), after which you can listen to the deleted noise (Noise Only item). If something does not suit you, uncheck and edit the Noise Reduction and Reduce by options. Save the fingerprint (Ctrl + Shift + P) and remove the clutter.
Note: if you have a pre-recorded noise fragment, you can also download it as a print. If a piece of noise was already recorded in the track before the start of the game, you can make it stand out and then make editing based on it.
Additional tools
Now let's see how to remove noise in Adobe Audition, which can be attributed to standard interference. For example, using the Dhummer tool, you can get rid of the hum of the mains by selecting a template corresponding to a frequency of 50 Hz.
Auto Heal, DeClipper or DeClicker tools are good for removing clicks, cod, or something similar. If additional plugins are connected to the program, for example, of the VST or RTAS formats, it is advisable to use the DeEsser effect to clear the vocals. In addition, among these plug-ins you can find many additional "lotions" of narrowly targeted action, for example, to remove the noise of guitar pickups, pickups when using too long cords, and to suppress all kinds of noise manifestations when using the Fuzz and Overdrive effects. In general, for each case, you can find several universal solutions.
Note: in order to simplify your work due to the complexity of the described application, novice users can recommend using the Cool Edit Pro program, on the basis of which Audition was actually created (by and large, the whole package just changed the sign, and the toolkit for work with audio). Finally, do not forget about plug-in third-party plugins. Among them, the choice of the right tool is much wider.
