Stream-independent sound to haptic effect conversion system
A haptic conversion system is provided that receives a plurality of audio streams of an audio signal. The haptic conversion system further determines, for each stream of the plurality of streams, whether at least one parameter of the one or more parameters indicates that the corresponding stream is to be converted into a haptic effect, and thus, identifies one or more streams that include at least one parameter that indicates the corresponding stream is to be converted into the haptic effect. The haptic conversion system further generates, for the identified streams, a haptic signal based on each corresponding stream. The haptic conversion system further sends, for the identified streams, each haptic signal to an actuator to generate a haptic effect.
