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 1):
An apparatus comprising:\n a receiver configured to receive an encoded bit-stream, 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; and a decoder coupled to the receiver, the decoder configured to:\n generate a second harmonically extended signal at least partially based on a low-band excitation signal associated with the encoded bit-stream; \n scale the second harmonically extended signal based on the mixing factor to generate a first scaled signal; \n scale second modulated noise based on the mixing factor to generate a second scaled signal; \n combine the first scaled signal and the second scaled signal to generate a high-band excitation signal; and \n reconstruct the audio signal based on the high-band excitation signal.
