A METHOD FOR GENERATING A RECONSTRUCTED SIGNAL |
摘要 |
A method for generating a reconstructed signal comprises: receiving a signal containing data representing a baseband signal derived from an audio signal and an estimated spectral envelope; obtaining from the data a frequency-domain representation of the baseband signal, the frequency-domain representation comprising baseband spectral components; obtaining a regenerated signal comprising regenerated spectral components by copying into individual subbands the lowest-frequency baseband spectral components to a lower edge of a respective subband and continuing through the baseband spectral components in a circular manner to complete a translation for that respective subband; and obtaining a time-domain representation of the reconstructed signal corresponding to a combination of the baseband spectral components, the regenerated spectral components and the estimated spectral envelope. |
