1. A method of performing an inverse overlap transform used to decode digital media using a digital media decoding device, the method comprising: with the digital media decoding device, performing an inverse frequency transformation on digital media; and with the digital media decoding device, applying a plurality of overlap operators to results of the inverse frequency transformation, the plurality of overlap operators including at least a first overlap operator and a second overlap operator, wherein the first overlap operator is an interior overlap operator, and wherein the second overlap operator is an edge or corner overlap operator, each of the plurality of overlap operators being characterized by substantially equivalent DC gain.
