Abstract
An audio system includes a first transformation device provided with an input audio signal and which transforms the input audio signal from the time domain to the frequency domain resulting in an input spectrum. The system also includes a spectral processing device, which is connected downstream from the first transformation device, that receives the input spectrum and produces from it an output spectrum with a dynamic range that is reduced from that of the input spectrum. The system further includes a second transformation device connected downstream from the spectral processing device, and provided with the output spectrum. The second transformation device transforms the output spectrum from the frequency domain to the time domain, and provides an output audio signal.
