Problems solved by technology
However, when displaying the spectrum animation, it was found that some models had the problem of animation freeze, and the animation could not be played smoothly, which brought a bad experience to the user. After preliminary investigation, it was found that the data return interval was too long when the player called back the spectrum data. long, so it is necessary to optimize the animation effects for this problem

The invention relates to an audio-driven animation special-effect generation method, which comprises the following steps of: when an audio is played, acquiring frequency spectrum data corresponding to the currently played audio in batches, and caching the frequency spectrum data in a first cache region and a second cache region in odd number times and even number times respectively; alternately acquiring the cached frequency spectrum data from the two cache regions, and generating a frequency spectrum animation; further judging whether the next batch of spectrum data is cached or not; if the next batch of spectrum data is not cached, acquiring transition frequency spectrum data through the processing logic of frame insertion and frame compensation based on the currently cached frequency spectrum data, and caching the transition frequency spectrum data in a third cache region; and informing that the next batch of spectrum data is temporarily acquired from the third cache region, and generating a frequency spectrum animation. According to the invention, the processing logic of frame insertion and frame supplement is adopted, the frame rate is improved through the algorithm, the refresh frequency is prevented from being lower than the animation standard (24 frames per second), the frequency spectrum animation is smoother, and the situation of animation jamming is reduced.
Description
technical field [0001] The invention relates to the technical field of audio visualization, in particular to a method for generating audio-driven animation special effects. Background technique [0002] Existing players can present animation special effects at the same time when playing audio to increase user experience. The more commonly used animation special effects are spectrum animation. The existing spectrum animation presents the music spectrum corresponding to the currently playing audio to the user on the display interface , you can visualize the pleasant sound in your ears, as if you can see the sound in front of your eyes. However, when displaying the spectrum animation, it was found that some models had the problem of animation freeze, and the animation could not be played smoothly, which brought a bad experience to the user. After preliminary investigation, it was found that the data return interval was too long when the player called back the spectrum data. Th...
