I was sitting contemplating lossy audio compression and the concept that you can throw away data and have the result be perceived just like the original — perceptual transparency. I then wondered to myself, is there a sound of the data thrown away? I.e. the sound of that which is not perceived.
Does anyone know how this would be calculated or even if there are any examples of this posted on the interwebs somewhere?"
