| 摘要 |
The invention relates to a device and a method to process audio signals. Said device comprising an input, an output and a continuous signal propagation path extending from the input to the output for audio signals applied to said input. The device further comprises in the signal propagation path from said input towards said output in the given order a first linear distortion generating unit (20) having first transfer characteristics, a nonlinear distortion generating unit (30) having nonlinear transfer characteristics to generate frequency-dependent distortion of the linearly distorted audio signal, and a second linear distortion generating unit (40) having second transfer characteristics, wherein said second transfer characteristics corresponds essentially to the inverse of said first transfer characteristics. The inventive method comprising subjecting said audio signals to first linear distortion characterized by first transfer characteristics, then subjecting the obtained linearly distorted audio signals to frequency-dependent nonlinear distortion, and then subjecting the thus obtained nonlinearly distorted audio signals to second linear distortion characterized by second transfer characteristics, said second transfer characteristics being provided essentially as the inverse of said first transfer characteristics. |
