If you record a sound file in an environment that contains background noise then it is inevitable that your audio will be partly contaminated by the noise. You can use the Audacity audio-editing application to eliminate a buzzing noise or any other unwanted noise from an audio track. To eliminate buzzing, first direct Audacity to analyse a part of the track that contains only the buzzing noise. Then use the application to eliminate that noise from the entire sound file.
