Abstract
A method includes converting an audio signal of a current time period to a frequency domain to produce a set of frequency coefficients. For each of the frequency coefficients, the method includes computing a gradient of that frequency coefficient's magnitude relative to a magnitude of the same frequency coefficient from a previous time period. The method then includes summing the gradients computed for the set of frequency coefficients to produce a sum value, and then generating a haptic signal based on the sum value.
