Music Production & Sound Engineering Tutorial - Noise Reduction - Cleaning a solid File

With this tutorial I will be utilizing a sound file of a vocal recording. I'll be using 'adobe audition' to edit this sound file. 'Adobe audition' is a preferred model of audio recording software. This software allows you to record, edit and mix sound files/recordings on independent tracks. It has plenty of tools to edit/engineer your sound files the same manner you would like them to be.

This tutorial will show you how to use the noise reduction tool to remove unwanted sounds/background noise from your recording or any sound file. I am using adobe audition let's imagine but any decent sound editor will have it.

The initial step is to identify an appropriate section of the sound file which has the noise. A good method to find is the fact that which represents a pause between your speech/vocal. Much like whenever you take a pause relating to the sentences or words when you're speaking normally. It will pay to focus with all the software to get a nice clear look at the part your would like to work with. This is the section that will be accustomed to tidy up the complete sound file. Once you have zoomed in on your chosen section it'll be apparent that where it must be a silent pause i know of a basic noise. Here is the section that we'll sample after which remove from your entire sound file.

Generally when you record any sound there is certainly often a quiet hiss or humming (noise) which can be heard during playback. This may come from the recording equipment itself or from background sounds which are inside range of the recording equipment. It's generally thought to be noise because they are usually unwanted sounds. Engineering Melbourne

In addition to noise you'll also find other quiet looking elements of the sound file that represent the sound of someone breathing in. You will usually see these breath sounds right before a vocal part begins. These breath sounds will always be recorded with voice recordings if you don't make use of a microphone that only records outward sound. An alternative choice is always to possess a skilled vocalist! Some individuals decide to remove or reduce the volume of this breath sound however that must only be performed after you have removed the root noise of the entire track first.

Now we'll eliminate the noise!

Highlight the silent pause/noise. This is achieved inside the very same manner while you would highlight text inside a text document. Try not to select some of the vocal part when making your selection. You might like to focus to ensure your accuracy for this section of the process. To sample this noise in 'adobe audition' right-click with that highlighted section and click on "capture noise profile" in the menu that seems.

This tells the program (adobe audition) what you consider is the noise (sound frequencies that you might want to eliminate or reduce). The next thing is to to go forward and remove this noise in the entire sound file. In 'adobe audition' this is accomplished using the noise reduction tool.

Whichever sound editing software you decide to utilization in your studio setup, the technique can vary greatly slightly, however the basic steps and terminology will be really similar.

Next, click on the "effects" menu towards the top of the screen then select noise reduction in the menu that seems. Once you have done this a brand new window will be. This window represents the noise reduction tool and displays all the options and relevant details about that tool. The noise that you simply captured earlier would be the default noise used by it. You can either completely eliminate the noise or you can just decrease the noise for an acceptable level using the "noise reduction level" variable shown in the image. In the event you click the preview button you are able to listen to what the alterations will sound like before permanently applying them. This can be helpful to tweak the amount of effect you want to apply.

It is important to be careful and listen carefully during this period with the process because frequently it's easy to apply an excessive amount of noise reduction. This may effect the entire sound of the file in a manner that you did not intend. When you're satisfied with the settings click the OK button and the noise is going to be removed. Magic!

You may then see complete silence where the silent pauses between the vocal waveforms are. At this time you'll have successfully removed the unwanted noise from your entire duration of sound file. This could be seen most clearly through the completely flat line (zero decibels/volume) where the pauses are. At this point you might want to adjust the volume of the breath sounds discussed earlier if you think it is appropriate. Engineering Melbourne

It is useful to eliminate noise within all of your vocal recordings because when you've got several vocal tracks playing at the same time it also means you have several layers of noise. This noise can easily go unnoticed however it can sometimes slightly muffle other sounds/frequencies such as your musical parts or beats. When confronted with mastering, mixing and balancing the entire mix this can be a useful and important tool for any quality production and permits the beat/music to be heard superior.
