Method and apparatus for decomposing a stereo recording using frequency-domain processing employing a spectral subtractor
摘要
An apparatus for generating a stereo side signal having a first side channel and a second side channel from a stereo input signal having a first input channel and a second input channel is provided. The apparatus comprises a modification information generator (110) for generating modification information based on mid-side information. Furthermore, the apparatus comprises a signal manipulator (120) being adapted to manipulate the first input channel based on the modification information to obtain the first side channel and being adapted to manipulate the second input channel based on the modification information to obtain the second side channel. The modification information generator (110) comprises a spectral subtractor (115) for generating the modification information by generating a difference value indicating a difference between a mono mid signal or a mono side signal of the stereo input signal and the first or the second input channel.
