Method and device for transposing the frequency of an input signal, in particular for hearing aids, comprising: - an analytical circuit (AS) with which are produceable a momentary frequency signal w(t) whose strength is proportional to the momentary frequency of the input signal ui(t) and a momentary amplitude signal A(t) whose strength is proportional to the momentary amplitude of the input signal ui(t); - a voltage-controlled oscillator (VCO) which is connected to the output of the analytical circuit (AS) that supplies the frequency signal w(t); - a multiplier (M) with two inputs, of which one of them is connected to the output of the voltage-controlled oscillator (VCO) and the other to the output of the analytical circuit (AS) supplying the amplitude signal A(t).
