How to fix "Church Sound" echoes

Sometimes we can do the seemingly impossible, but I'm afraid that miracles are generally beyond us, and that's pretty much what you are asking for, I'm afraid. The chances are that if you have camera mic audio from the wrong end of a church, with a congregation between it and you, that there will be very little indeed that could be rescued from it. That said, if the humming is, as I suspect, from the camera itself and pretty constant then you stand some sort of chance of removing this, either with noise reduction or the sound remover tool. The bottom line though is that you will never get any real clarity of sound from that sort of distance unless you've used some serious surveillance equipment to record it - and even then it won't be brilliant.

If you want a more specific answer as to what if anything is possible, you'll have to put a clip of it (a direct copy of the original, not an MP3) onto Dropbox and put its public link here - the forum won't support audio files directly.
