Abstract
A system is provided that produces haptic effects. The system receives an audio signal that includes a low-frequency effects audio signal. The system further extracts the low-frequency effects audio signal from the audio signal. The system further converts the low-frequency effects audio signal into a haptic signal by shifting frequencies of the low-frequency effects audio signal to frequencies within a target frequency range of a haptic output device. The system further sends the haptic signal to the haptic output device, where the haptic signal causes the haptic output device to output one or more haptic effects.
