APPARATUS AND METHOD FOR GENERATING BANDWITH EXTENSION SIGNAL |
| 摘要 |
An apparatus for generating a bandwidth extended signal includes an anti-sparseness processing unit to perform anti-sparseness processing on a low-frequency spectrum; and a frequency domain high-frequency extension decoding unit to perform high-frequency extension encoding in the frequency domain on the low-frequency spectrum on which the anti-sparseness processing is performed. |

1. An apparatus for generating a bandwidth extended signal, the apparatus comprising:
at least one processing device configured to: perform noise filling on a decoded low-frequency spectrum; perform anti-sparseness processing by which a constant amplitude component is inserted into spectral coefficients remaining zero in the decoded low-frequency spectrum on which the noise filling is performed; and generate a high-frequency spectrum by using the decoded low-frequency spectrum on which the anti-sparseness processing is performed. |
