Abstract: A method for minimizing post-playback oscillation during playback of a haptic playback waveform to a haptic transducer may include determining whether a frequency response of the haptic playback waveform has a notch with a notch frequency at approximately a resonant frequency of the haptic transducer and, responsive to the notch frequency differing from the resonant frequency, modifying the haptic playback waveform for playback to the haptic transducer by shifting the notch frequency to approximately the resonant frequency.
