The processor is configured to receive an audio file, or a haptic file generated from the audio file, that includes a first channel having a first set of control parameters to generate a first haptic effect and a second channel having a second set of control parameters to generate a second haptic effect and to output a control signal that includes the first and second sets of control parameters for the haptic effect. The haptic output device is configured to receive the control signal from the processor and to output the haptic effect to the haptic peripheral. In an embodiment, the haptic output device is coupled to a bi-directional trigger and the control parameters move the trigger in opposing directions. In another embodiment, the control parameters generate different timelines of haptic effects to a user input element. ## Claims ### Claim 1 A system comprising: a processor configured to receive a file including a first channel having a first set of control parameters to generate a first haptic effect and a second channel having a second set of control parameters to generate a second haptic effect, and configured to output a control signal that includes the first set of control parameters for the first haptic effect and the second set of control parameters for the second haptic effect, wherein the file is an audio file or a haptic file generated from the audio file and the audio file is generated via panning of a sound signal;
