1. A system for outputting haptic effects comprising:
- a processor configured to;
receive an audio signal;
determine an envelope signal associated with the audio signal, wherein determining the envelope signal comprises;
determining a Fast Fourier Transform of the audio signal within two or more time windows;
determining a magnitude for the Fast Fourier Transform for each time window;
determine a haptic effect based in part on the envelope signal;
output a haptic signal associated with the haptic effect;
an audio output device configured to receive the audio signal and output an audible effect;
a data store configured to receive the haptic signal and store the haptic effect in a haptic track on the data store; and
a haptic output device in communication with the processor, the haptic output device configured to receive the haptic signal and output the haptic effect.
