ESTIMATION OF MIXING FACTORS TO GENERATE HIGH-BAND EXCITATION SIGNAL |
摘要 |
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. |
