Do you want to make your podcasts more professional?
In this video, we will show you how to remove unwanted noise from your podcast. There are a lot of options you can consider to do when it comes to post-production for your podcasts. As Paul mentions in this video, one of the best things you can do is make sure your podcast is recorded with the best quality audio possible up front. This means using an EQ, Compression, Noise Gates and other digital audio effects such as VST3 plugins. We cover all of this in our podcasting course and tutorial videos here on YouTube.

Once your podcast audio is sounding great live the next step is to tweak the audio in post-production. Audio post production can be complicated but we are simplifying the audio post-production down to removing unwanted noises. Now we could get rid of many breathe sounds with a high noise gate it can be complicated to use a noise gate this way because it can sound unnatural.

We discuss two easy ways to remove the sound of a breath in your podcasts in this video. One is to simply use the noise reduction tool. This will muffle the sounds of the breath and make it almost imperceptible. Generally, when you are talking to someone you can’t hear them breathing. Because the microphone is so close to their mouth you can actually hear them breathing and that does not sound good on a podcast. So you have two choices when it comes to noise reduction. You can take a “Noise Profile” of the portion of your audio that you want to remove and then apply it to your entire audio recording OR just the portions of the audio that you want to effect.
Another way to remove the breath sounds is to simply silence each one. In this video, Paul is recording audio for an important commercial so completely removing all breathing sounds is done manually. Depending on your level of audio production you may choose to do one of these techniques or both.

Audacity is a great, free-of-charge audio editing software. In today’s tutorial, you will find out how to remove background noise.
It is probably the most common task for people recording voice-overs in not perfect conditions. I myself have got this problem as my PC is fairly noisy and even though I have a good microphone some noise is usually recorded. Nothing to worry about, thanks to Audacity useful function we can quickly remove it. Here are just 3 steps you need to take.
Removing background noise in Audacity#1 Record background noise
First things first. You need to provide a sample of the background noise so the program could separate it from the recording. The easiest way to achieve that is to record ‘silence’. Basically, you record your voice over or other sounds and at the end of the recording, you do not immediately hit the stop button. Instead, you wait for a couple of seconds and continue recording. By doing so, you will record background noise.
Have a look at the screenshot below. You will see on the left voice recording and then, the recording of the silence. As you can see, it is not the silence, the line is not perfectly flat which means that the background noise has been recorded.
#2 Get the noise profile
Now we need to let the program know what is the noise by ‘Getting the noise profile’. Use your mouse to select the noise (do not select your voice recording, only the noise). Then from the top menu go to Effects/Noise Reduction. You should see this window:
As you can see, there are a few options available. Because I am not an expert, so I leave them alone and just hit Get Noise Profile button. But you can adjust some setting and see how the process worked out. There’s a risk that the noise reduction will be too aggressive and it will distort the voice itself. If this happens, you can always go back, change the settings again and improve things.
#3 Remove the background noise
So at this stage, the noise profile should be registered in Audacity and all we have to do is to delete the noise. Press Ctr+A (or Command+A on Mac) to select the whole recording. Go again to Effects/Noise Reduction. But this time press OK button to remove the background noise:
The uneven line with the noise should be flat now. Also, it is a good idea to listen to the recording to check if it is not distorted. If everything is fine, that is all, just trim the recording on the left to remove the silence. If you are unhappy with the results, press Ctr+Z (Command+Z on Mac) to undo removal of the noise. Go back to step 2, change the Noise profile setting and remove the noise again in step 3.
