摘要
Disclosed is a method and system of authoring an audio signal to produce an immersive haptic experience. The method and system preprocesses the audio signal in a preprocessor, which is passed to an audio analysis module. The audio analysis module processes the audio signal for a to produce (a) an array of time amplitude values, and (b) an array of spectral centroid values. In another implementation, the audio analysis module transforms the audio signal using Fourier transformation to produce an array of time amplitude frequency values and an array of spectral centroid values. The array of time amplitude values and the array of spectral centroid values are passed to an authoring tool. A user can modify the array of time amplitude values, the array of timer frequency values and the array of spectral centroid values to adjust the audio signal. The authored audio signal is provided to a transformation module, which transforms the audio signal into a transformed audio signal for producing a computer-readable file. The computer readable file can be stored and passed to a resynthesis module for producing immersive haptic experience. In one variation, the transformed audio signal can be directly synthesized using the resynthesis module. In an alternate embodiment, the authoring tool may be bypassed and the array of time amplitude values and the array of spectral centroid values are automatically edited using deep learning algorithms or artificial intelligence algorithms to generate haptic output in real time for producing haptic effect using one or more actuators.
