    Patent number: 7702115
    Abstract: A method and apparatus to reconstruct high-frequency components of an input audio signal. The apparatus includes a frequency inverter to invert the frequency spectrum of the input audio signal, a band pass filter which filters out the higher frequency components of the input audio signal, a converter which shifts the frequency spectrum of the filtered signal to create a correction signal, and an adder which adds the correction signal to the input audio signal to obtain a reconstructed audio signal.
