Your mix is full of synthesized analog instruments - but something is missing! YES! THE SOUND OF A CABLE LYING ON THE FLOOR SOMEWHERE NEAR AN ELECTRIC LINE. Line Hum gives you this missing piece of Analog authenticity, As well as a variety of noisy wave forms, this Audio Unit is also able to just sit there and drone on any frequency and ring modulate its input for added distortion. It's actually pretty useful, especially when you run a bunch of them serially or in parallel. Because this is an Audio Unit, you need to run the (non functioning) Line Hum app to install it.
