A method of providing a haptic signal is described therein, the method comprising the steps of providing a first source signal, filtering a mid-range band of the first source signal for restricting a bandwidth of the first source signal to the mid-range band, integrating the filtered mid-range band of the first source signal to identify an amplitude of the filtered first source signal, providing a voltage control amplifier with a proportional calibrated voltage on a basis of the integration of the filtered first source signal for adjusting an amplitude of the filtered source signal, isolating a trans-conductance voltage control amplifier high impedance output from a second source signal with a buffer, filtering the filtered source signal with a low pass filter to identify original sub-frequencies of an audio program and combining the identified original sub frequencies of the audio program with transposed midrange frequencies in a haptic signal.
