Hello, recently i have shot footage, in which there is a hum in the background, the hum is not extremely loud, but loud enough to be noticed. the voices talking in the background are extremely crisp. Is there a way i can keep the voices crisp in the audio while removing the hum? also I am not too familiar with the audio filters in FCE if someone would like to give me a step by step on what to do that would be awesome, i also have sound samples if anyone wants them. Thanks for everything.
