Software to Remove Audio Noises - What to Do With the Terrible Noises in the Audio of Your Recordings
- Written by Rodrigo Marques
If you are looking for a software to remove audio noise from your recordings, then let's take a brief look at what you can do to accept or even correct those unwanted noises. We'll look at at least two approaches you can use to remove noise, and also ways to keep those noises from occurring. Come on?
The Key Audio Noises We Found in a Home Studio
We've been talking about how to restore the saturated audio of a song in a video on our YouTube channel and this is a very controversial topic because sometimes we run into problems with no solution, or the solution does not please its simplicity or people don't believe their recording went to space without at least participating in some NASA training. Yes, your recordings can go into space very easily, especially if you're not using a decent production process to perform recordings, mixing, and even mastering.
If too great care is not taken, your recording may even become a circus of horrors impossible to control. That is why the slogan of Formula HSF talks about "More Control = High Quality".
If the noise is caused by "data loss" as is the case of saturation, as many say: the audio "cracked", "burst", then, unfortunately, I will have to reinforce here that there is nothing to do with this. You lost data when the equipment limits were exceeded, and in those moments nothing was recorded, other than a continuous peak of electricity, with no information that can be recovered. Be clear: it's practically impossible to recover saturated audio, okay?
Another type of noise that can be recovered is the white noise of the Universe. I had already spoken of NASA, now I'm talking about white noise of the Universe, soon we will have to change the site name to Home Studio Astronomy, right? Joking aside, there is rather a noise everywhere, which is called "background noise" that comes from outer space, or whatever exists out there.
The fact is that this kind of space background noise, yes, can invade your recording studio, it is often as punctual as a British and appears every time you start recording your audio. It is not very difficult to find a mixer of US$ 15.000 presenting this background noise. Which is totally normal if this noise is floating below -50 decibels. I'm not nauseous, our standard only regards something as noise if it's stronger than -50 dBs.
Remembering another noise here is the radio sources that are all over the planet Earth ... It is true, today I am very astronomical indeed. The truth is that there are communications on a huge variety of radio frequencies, from the highest to the lowest, some of them transmitted in the Kilo Hertz range and believe; if we had good ears, we could hear these radio waves in some way, because they are within our hearing range.
Then I want to make a video showing these radio waves and even a curious case of an album by an artist very well known worldwide where one of these radio signals ended up appearing on the recording, being replicated on the disc and even sold to millions of fans. A classic example of RF interference in a recording of a highly regarded studio in Great Britain.
So if you have some noise like that, don't despair, because it is quite possible to solve these problems, even before recording. As you will see next.
How to Remove Noises from Recorded Songs
If you've recorded everything, and even though you've done your homework right, it still has a background noise greater than - 50 decibels, the solution to this is to use some noise remover software, which is what you thought to do and that's why you're here listening to me talk about noise.
Without further ado, I can recommend the most efficient way to remove noise that is using a Direct-X plugin such as Noise Reduction 2.0, which comes with Sound Forge Pro. This is the exact plugin I use to do the mastering and is a The one that gives the best results for you that you want to try to recover some recording.
Waves Audio also produces some good noise reduction plugins, such as Z-Noise and X-Noise, as well as the W43 Noise Reduction Plugin. These plugins are amazing and are able to do exactly what you need to eliminate the noises. These noises will not be eliminated only if they present very large artifacts, or problems of data loss in audio as in the case of audio saturation, of course.
Waves have a wide range of plugins, the cheaper ones being the Noise Suppressor that only serves to remove the simplest noise like microphones, or the X-Noise that has many more features and serves to remove the more complicated noises to From your audio. I speak much more about how it all works within the Home Studio Course - Formula HSF and if you are not yet a student click on the link below, check all the details and sign up today so that you can have contact with these In the real environment in which they work.
There are some people using only the Audacity Audio Editor to remove noise, but this is not a very simple task and it may be that only Audacity is not enough to solve your problem, so this time I'll leave Audacity out, here.
Preventing Audio Noises Before Recording
They say that prevention is better than cure and in this case, I also agree that preventing such noise is the best way to get to the end of our production without further problems.
I commented in another video on How to Improve Audio Recording Quality on Home Studio and there I mentioned the importance of a grounding in the computer of your audio system, and also in everything that is involved in the process of capturing the audio, to solve the problem of the RF pickup, the frequencies that pollute our atmosphere and that comes from all sorts of equipment you can imagine: from wifi routers, cell phones, FM radios, vehicle engines and a host of other unimaginable sources that produce RF. So the best solution to this is an electrical grounding, which will solve almost completely this type of problem.
Using good audio connectors is also a great way to avoid noise, making sure that these cables are always intact and not damaged if you step on them or run over them with the wheel of your executive chair.
Expensive equipment will not save you from noise, so you should also take care of your equipment, regardless of their price, even because noise suppressor circuits remove details of your audio that can't be removed in any way.
Education is the Best Tool to Remove Audio Noises from Your Audio Recordings
Finally, I believe that education is the best tool you can use to help reduce noise in your audio productions, whether those that are already undermined - using software like the ones we mentioned here - or even helping you to observe all your production process, so you don't make mistakes, and fall victim to some intrusive RF wave, coming from God knows where.
This was a brief overview on removing noise, and I come back to talk more in detail about this subject in a future exclusive workshop.
I hope these tips can help you to better handle your production process and that you get excellent results in your future productions.
I believe it is important that you gain your independence so that you can understand how it all works and that you are prepared to solve any technical problems that may arise during your recording sessions.
