Step 2: Remove background noise from audio using Audacity

Once the audio file is obtained from the video, use Audacity, an open-source free sound editor to remove background noise.

But remember, you cannot completely remove background sound of traffic or people, which is louder or at the same frequency as the main speech, music, or audio. To fix such loud background noise, first use a Notch Filter feature followed by Noise Reduction in Audacity. Notch filterhelps to remove resonances and line frequency between 50-60 Hz noise.

Follow the below steps to remove background noise:

  • Safely download Audacity on your computer from here.
  • Open Audacity.
  • Click File and import the audio file into Audacity.
  • Play the audio, select the portions of background noise.
  • Click the Effect tab on top.
