SPECTRAL ENHANCING METHOD AND DEVICE |
摘要 |
The invention concerns a method for spectral enhancement and a device therefor. The inventive method is a method for enhancing spectral content of a signal having an incomplete spectrum including a first spectral band, the method comprising the following steps: at least transposing the spectral content of said first band into a second spectral band not included in said spectrum to generate a transposed spectrum signal, with spectrum limited to said second spectral band; transforming the spectrum of the transposed spectrum signal to obtain an enhancing signal; combining the incomplete spectrum signal and the enhancing signal to produce a spectrum enhanced signal. The invention is characterised in that said spectral content is subjected to a whitening step. |
