I’m trying to prepare a load of my old shambolic recordings for some kind of release and there’s one song with a bit of feedback that I didn’t intend that has been bothering me for years. I’ve tried so many things to get rid of it. The tape is either long gone or at least on a different continent so I’m working with mp3s… the mix is a bit of a jungle and there’s no point where the feedback is alone. If anybody can help I’d be overwhelmingly grateful!!
Fortunately, feedback like that tends to happen in a regenerative, slightly resonant system. In English, it happens at a single pitch tone which makes it a stationary, easy target for the Audacity tools. If you have a very high quality PA system, sometimes those will howl at more than one pitch or they slide around. In that case you are, as the technical phrase goes, “in doo-doo.”
