Hi there, without hearing a sample, it's tough to say how hard it would be to dump the background noise. It's possible it can be done with filters, but you would have to build one (or several) based on the frequency of the background noise. I'd love to give it a try. I've been doing broadcast production for 15 years and haven't been stumped too may times. If it's possible, could you send me a minute or two of the audio. Thanks! Out-House Audio
