How to filter musical overtone/jamming of a vidios sudio content?

There is an ongoing international effert to control the information on the internet. It appears that here in the U.S. if they don’t want you to hear a message sent to you on the iternet, they overlay loud musical tones or noise that is louder then the audio message being spoke. I can’t be the only one that has this problem…so is there a filter out there that can eliminate the jamming without distroying the audio?
