Abstract
A haptic feedback method, system and related device for matching split-track music to vibration are provided. The method includes: acquiring raw audio data; obtaining multiple split-track audio data by splitting the raw audio data by using a predetermined deep learning model; calculating an energy proportion corresponding to a respective split-track audio data in the raw audio data; determining a weight of the respective split-track audio data according to the energy proportion; performing weighting calculation on the multiple split-track audio data according to a predetermined weighting rule, to obtain a time-frequency spectrum; generating a matched vibration signal corresponding to the raw audio data based on the time-frequency spectrum; and outputting a haptic feedback effect according to the matched vibration signal. The audio data can be matched to vibration, and a vibration feedback that more precisely matches cadences and rhythms of the audio data can be output.
