Abstract:
A method includes generating a high-band residual signal based on a high-band portion of an audio signal. The method also includes generating a harmonically extended signal at least partially based on a low-band portion of the audio signal. The method further includes determining a mixing factor based on the high-band residual signal, the harmonically extended signal, and modulated noise. The modulated noise is at least partially based on the harmonically extended signal and white noise.

Claim (Index 7):
A method comprising:\n receiving an encoded bit-stream at a speech decoder, the encoded bit-stream corresponding to an encoded version of an audio signal and including data representative of a mixing factor, the mixing factor based on a voicing factor and a high-band adjustment factor that is based on a high-band residual signal, a first harmonically extended signal, and first modulated noise, wherein the first modulated noise is at least partially based on the first harmonically extended signal and white noise; generating, at the speech decoder, a second harmonically extended signal at least partially based on a low-band excitation signal associated with the encoded bit-stream; scaling, at the speech decoder, the second harmonically extended signal based on the mixing factor to generate a first scaled signal; scaling, at the speech decoder, second modulated noise based on the mixing factor to generate a second scaled signal; combining, at the speech decoder, the first scaled signal and the second scaled signal to generate a high-band excitation signal; and reconstructing the audio signal based on the high-band excitation signal.
