System and method for automatically producing haptic events from a digital audio signal
摘要:
The system and method described is directed to receiving digital audio files and automatically converting the received files into haptic events. In an embodiment, the received files are of sampled digital or digitized analog audio files. The system and method separates the audio signal into a plurality of sub-band signals and segments the sub-band signals into a plurality of events. The system and method then assigns haptic effects to the events to produce haptic event signals which are to be output by an actuator. The system and method utilizes clipping and minimum time separation parameters along with physical parameters of the actuator and frequency characteristics in the audio signal to analyze and provide discrete haptic events which correspond with the audio.
