Title:
独立したノイズ充填を用いた強化された信号を生成するための装置および方法
Document Type and Number:
Japanese Patent JP7391930
Kind Code:
B2
Abstract:
An apparatus for generating an enhanced signal from an input signal (600), wherein the enhanced signal has spectral values for an enhancement spectral region, the spectral values for the enhancement spectral regions not being contained in the input signal (600), comprises a mapper (602) for mapping a source spectral region of the input signal to a target region in the enhancement spectral region, the source spectral region comprising a noise-filling region (302); and a noise filler (604) configured for generating first noise values for the noise-filling region (302) in the source spectral region of the input signal and for generating second noise values for a noise region in the target region, wherein the second noise values are decorrelated from the first noise values or for generating second noise values for a noise region in the target region, wherein the second noise values are decorrelated from first noise values in the source region.
