Publisher's Synopsis
A method includes generating a first signal corresponding to a first component of a high-band portion of an audio signal. The first component has a first frequency range. The method includes generating a high-band excitation signal corresponding to a second component of the high-band portion of the audio signal. The second component has a second frequency range differs from the first frequency range. The high-band excitation signal is provided to a filter having filter coefficients generated based on the first signal to generate a synthesized version of the high-band portion of the audio signal.
