| 发明名称 | Methods and systems for perceptual spectral decoding | ||
| 摘要 | A method for perceptual spectral decoding includes decoding of spectral coefficients recovered from a binary flux into decoded spectral coefficients of an initial set of spectral coefficients. The initial set of spectral coefficients are spectrum filled. The spectrum filling includes noise filling of spectral holes by setting spectral coefficients in the initial set of spectral coefficients not being decoded from the binary flux equal to elements derived from the decoded spectral coefficients. The set of reconstructed spectral coefficients of a frequency domain formed by the spectrum filling is converted into an audio signal of a time domain. | ||

| 主权项 | 1. A method for perceptual spectral decoding, comprising the steps of: decoding spectral coefficients recovered from a binary flux into decoded spectral coefficients of an initial set of spectral coefficients; spectrum filling said initial set of spectral coefficients into a set of reconstructed spectral coefficients, said spectrum filling comprising noise filling of spectral holes by setting spectral coefficients in said initial set of spectral coefficients not being decoded from said binary flux equal to elements derived from said decoded spectral coefficients; and converting said set of reconstructed spectral coefficients of a frequency domain into an audio signal of a time domain. | ||
