1. A method for converting an audio signal into one or more haptic effects, the method being performed by a processor and comprising:
- receiving a set of samples of the audio signal;
performing frequency filtering on the set of samples to generate a filtered set of samples;
generating a haptic signal by mixing the filtered set of samples with a periodic waveform; and
sending the haptic signal to an actuator to generate the one or more haptic effects.

Abstract
A haptic conversion system is provided that intercepts frames of audio data, such as a digital audio signal, converts the frames into a haptic signal, and plays the created haptic signal through an actuator to produce haptic effects. The haptic signal is based on a maximum value of each audio data frame, which defines a magnitude of the haptic signal. The haptic signal is applied to the actuator configured to receive the haptic signal, where the actuator utilizes the haptic signal to generate the one or more haptic effects.

16. A method for converting an audio signal into one or more haptic effects, the method comprising:
-
receiving a set of samples of the audio signal; determining a maximum value of the set of samples; performing frequency filtering on the set of samples to generate a filtered set of samples; determining a first waveform that is based on the filtered set of samples; determining a second waveform that is based on a periodic waveform, wherein the periodic waveform has an amplitude that is based on the maximum value of the set of samples; generating a haptic signal that is a sum of the first waveform and the second waveform, and sending the haptic signal to an actuator to generate the one or more haptic effects. - View Dependent Claims (17, 18, 19)
