NOISE FILLER, NOISE FILLING PARAMETER CALCULATOR, METHOD FOR PROVIDING A NOISE FILLING PARAMETER, METHOD FOR PROVIDING A SPECTRAL REPRESENTATION COMPLETED WITH NOISE OF AN AUDIO SIGNAL, A CORRECTED AUDIO COORDINATED PROGRAM.

摘要

Noise filler (100) to provide a spectral representation (112) filled with noise of an audio signal on the basis of a spectral representation (110) of input of the audio signal, the noise filler comprising: an identifier (120 ) of spectral region configured to identify spectral regions (422e, 422f, 422g) of the input spectral representation (110) quantified to zero and separated from regions (420a, 420b, 420c, 420d) non-zero spectral representation of the representation (110 ) spectral input through at least one region (422a, 422b, 422c, 422d, 422h, 422i, 422j, 422k) intermediate spectral, to obtain spectral regions (422e, 422f, 422g); and a noise inserter (130) configured to selectively introduce noise into the spectral regions (422e, 422f, 422g) identified to obtain the spectral representation (112) filled with noise from the audio signal.
