How to Remove Noise from Video using Sony Vegas Pro & Audacity

Sony Vegas Pro is one of the best video editing tool if you are using Windows. Even then it does not come with a Background Noise Removal Program of its own which brings in major drawback unless you are using a powerful microphone. Now since not everyone can afford such costly microphone, in this post I will tell you how to use Audacity along with Sony Vegas Pro to remove noise.

Note: Sony Vegas Pro does come with a Audio FX called as Sound Restoration but it does not work as good compared to Audacity. Since Audacity is a free tool, I will suggest you to use it.

Setting up Audacity:

  • Go to Options and then preferences. Switch to Audio Tab.

  • So browse and select audacity.exe.

Once you do that, it will export audio part of the video into Audacity and launch it. The next windows you will interact with is Audacity.

Noise Removal Using Audacity:

Now that you have the file in Audacity, first figure which part of the audio can be used as Noise. Audacity will use that as sample to remove noise.

  1. Select part of the audio file which has noise.
  2. Go to Effect and then choose Noise Removal.
  3. Hit the get Noise Profile button. It will disappear instantly as you do that.

  6. Once you are happy, click on Apply.

  • Now right click on the audio track which is on the left and deleted it.
  • Next drag and drop the filtered audio.

    I dont know man! I tried audacity myself. But I wasn’t very happy with the results. The best way to reduce noise is to not have it initially I think!
