Hi ElaJones, If you use Audacity (free download) to record your audio, there´s a tag (Effects) to apply Noise Reduction to the whole audio. When you do it the first time, just select the section of the audio (where the noise is) for the program to understand what kind of noise it has to reduce. After that, run the Noise Reduction a second time in the whole audio. It might help. Best of luck!
