Garageband Remove Background Noise Free

Getting rid of background noise in Garageband is pretty simple, and while there are many more sophisticated plug-ins for noise gating available on the internet, I would say that, from what I’ve experienced thus far, the stock noise gate that comes with Garageband works just fine.

In this tutorial, I’m going to run through how to quickly use a noise gate to eliminate unwanted sounds in a Garageband recording, and I’ll also direct you to a more sophisticated noise gate plug-in.

Moreover, I’ll also show you how to manually go into your vocal tracks and actually delete the undesirable sounds from your recordings, rather than just gating them.

First things first, I’ll show you how to set up a simple gate.

How To Set Up A Noise Gate

With Garageband open,

1) Go down into the Smart Controls with your vocal track selected, and notice the little box and the text beside it that says, “Noise Gate.”

2) Check the box off, meaning that now, your noise gate is turned on.

3) Slide the noise gate bar over to the desired dB setting until the noise has been completely eliminatedusually between -50dB and -15dB

Using the tool, you may connect remotely to the computer based on Mac OS system from the machine, where Windows is installed, and vice versa. In this article I am going to describe precisely how to use TeamViewer to control Mac from PC and on the contrary. Mar 19, 2020  Teamviewer allows you access to computers remotely. It works for Mac, PC, and Mac to PC remote access. Both computers need to have Teamviewer installed before using it. Once they install. TeamViewer Host is used for 24/7 access to remote computers, which makes it an ideal solution for uses such as remote monitoring, server maintenance, or connecting to a PC or Mac in the office or at home. Install TeamViewer Host on an unlimited number of computers and devices. As a licensed user, you have access to them all! Re: controlling a mac from pc Yes, install TeamViewer on both and log into your Contacts and Computers and you should be able to control each from the other. If my post was helpful, Please throw me a Kudos. Can you use teamviewer from pc to mac. If you wish to have remote access to your Mac computer from any device in the world at any time, TeamViewer can enable you to connect through a web browser alone. To make use of the Mac remote access feature from your mobile, you simply need to install the app on your iOS device first.

You can choose at which rate you’re going to set the noise gate, and of course, it really depends on what you’ve recorded and how loud the signal is, however, there is typically a range which sounds the best, and I would say that between -50dB and -15dB is the best area to be in.

For instance, on the latest track that I mixed for a client, I set the Noise Gate to around -20dB, and I’m sure that the client used a gate when he was recording as well.

Be careful not to turn the noise gate up so much that you eliminate all of the little sounds (transients) that make it sound authentic and human unless your goal is to make it sound “too perfect.”

Moreover, you might find that too much gating will create a choppy vocal during a quieter part of the singing/speaking. In combination with a compressor, the noise gate is very useful.

In terms of where it should be in the signal chain, you want to use the Noise Gate right after wherever the noise is coming from.

How To Set Noise Gate

If you’ve used a compressor to increase the quiet sounds and decrease the loud sounds, you might find that it brings up the undesirable sounds in the background.

In this case, you can use the Noise Gate after the compressor rather than before.

Here’s what I mean by the order of the plug-ins in the signal chain – the image below illustrates what I’m talking about.

Noise Gate Tips

Also, notice that the Noise Gate comes with its very own pre-sets in Garageband.

Click the Noise Gate plug-in the Smart Controls, and then in the Drop-Down menu, you can see the presets that come with it.

There are seven of them: Acoustic Bass Gate, Backing Vocal Gate, Electric Bass Gate, Fast Gate, Hard Floor Noise Cut, Percussion Gate, as well as Tighten Up.

How To Eliminate Unwanted Background Noise Manually

In many cases, you might find that it’s better to move to actually go into the vocal track and eliminate the unwanted sounds manually, rather than gating merely everything.

Here’s how to do this:

1) Double click the Audio Recording in the Workspace to highlight it.

2) Zoom in to the track by using the Zoom function on your trackpad.

Zooming in on the audio file in the Smart Controls will allow you to see all of the little noises in the wave format.

3) Isolate the parts of the audio recording that you want to get rid of, and then use the (Command + T) function to actually cut them out.

a) Use the (Command + T) function to cut the first offending part.

b) Then move the Rule over to the next part and use the (Command + T) function again.

You’ve created a little square, and you can select the square, and then delete it from the audio track entirely.

By doing this manually, we can actually delete the offending parts straight up, including the moment the singer takes a breath before starting to sing.

You can isolate the breath in the audio track and then delete it.

Once you’ve done this, you’re going to find that you run into problems later, however, when it comes to whether you want to duplicate that very same audio region and then loop it.

For instance, if you go through your vocal track, deleting each undesirable audio region, you’ll notice that you can’t loop it, due to the fact you deleted the parts out of it, essentially separating the vocal track from each other, and making it more than one track, rather than all combined as one.

If you try to use the (Command + J) function to merge the tracks together again, you’ll be right back where you started – the breaths and unwanted noises included, however, there is a way of getting around this.

Through the creation of a brand new audio file, as well as the (Command + J) function, you can actually make a new and improved audio file where the breaths and all of the undesired sounds have been eliminated, however, if you try and do it without creating a brand new file, the (Command + J) function will just combine the tracks together and those mistakes and little errors that you deleted before will come right back again.

This is a little bit tricky, so pay close attention.

How To Create A New Background Noise-Free Vocal Track

At this stage, you’ve gone through your vocal track and cut out all of the undesirable sounds, including the unwanted breathing right before the vocalist sung their first word.

Eliminate

1) Use the (Command + D) function to create an entirely new track with duplicate settings.

2) Copy and Select all of the edited vocal track, the one where you’ve eliminated all of the undesirable sounds, and then copy and paste it into the new Track Region, which is going to look like what you can see in the image below.

3) Select the new audio track and use the (Command + J) function to create an entirely new audio region without the unwanted noises and breathing.

Garageband will bring up a warning that says that for a new file to be created out of “noncontiguous” audio, a new track has to be created.

It’s worth noting that if you don’t get this warning sign, then what’s going to happen is that you’re just going to merge the tracks together again and wind up with very same breaths, errors, and background noise in the new track.

You want to click Ok, and then voila, you have a brand new track without the breathing and mistakes, and then you loop it however much you want.

Noise Gate Plug-Ins

In terms of what plug-ins you can actually get your hands on, I would say the most popular free plug-in for Noise Gates is the Bob Perry Noise gate which can be found on VST4Free at the link here.

This noise gate is more sophisticated than the stock plug-in that comes with Garageband, and it’s more realistic to the analog noise gates that you’d actually see in a professional recording studio or in a musician’s home.

Similar to the compressor, it has a few different parameters, including the Threshold, Attack, Hold, Release, and then the Range.

It has a few other parameters as well, including two toggle switches on the left and right-hand side.

On the left side, it has the “Curve” toggle switch.

The curve has three parameters, Curve, Log, and S-Curve

And then on the right side, there is the “Source” toggle switch.

This toggle switch goes back and forth from Side Chain and Channel.

We’ll talk about how to set up a more sophisticated noise gate plug-in in the future, as well as some of the other functions of a gate.

I hope this was helpful to you. In the future, I’ll dive deep into the Noise Gate, its parameters, and how to really get the best out of one.

Remove Background Sound From Audio

Disturbed by unwanted noise in silent passages of your Real Instrument recordings? No problem—meet GarageBand's noise gate.
Effects like distortion, overdrive, and amp simulators involve amplification of the Real Instrument's input signal. This amplification may also boost otherwise unnoticeable instrument and background noises. The noise gate can prevent these unwanted, low-level sounds from entering the effects

To reduce noise in a silent passage:
