This is not merely unzipping a file. The decoder must mathematically reconstruct the audio based on a "psychoacoustic model." It predicts how the compressed data should sound to a human ear, synthesizing frequencies that were stripped out during the encoding process. A high-quality decoder smooths out the "artifacts" of compression, preventing the audio from sounding hollow or metallic. (Subwoofer) for deep bass, like explosions or low rumbles
