Abstract

A sort of method for modulating audio signals, including the following steps: separation of the first and the second sound frequency signals from the sound frequency input signals, having the first sound frequency signal the frequency range corresponding to the lowest sound section and having the second sound frequency signal the frequency range corresponding to the highest sound section, and hybrid sound frequency output signals for output including sound frequency input signals and the first and the second sound frequency signals.
