Compared with the prior art, the invention has the following beneficial effects: according to the visual special effect display method for the lyrics of the music, the lyric special effect is automatically pushed and matched according to the pushing rhythms of the songs and the lyrics, and the processed special effect lyrics are projected to a screen, so that the effect that a lyric display system can display different lyrics according to songs of different styles is achieved; hundreds of specific lyrics are provided on the specific display screen, and the lyrics display and the work of the sound cavity are synchronously controlled by the mainboard, so as to ensure the consistency of sound and picture; therefore, the invention realizes playing different songs and displaying different special effects of lyrics, thereby improving the perception effect of the user; the invention randomly generates different lyric special effects for different songs and synchronously pushes the lyric special effects to the special effect display screen, so that the music is more visually displayed, and the immersion experience of the user is good.
Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are described in further detail below. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention.
A visual special effect display method for music lyrics comprises the following steps:
obtaining the authorization permission of a music software interface, and downloading the music software which is authorized to permit through a mobile phone;
reading music data of songs from music software, connecting the mobile phone with the special effect display screen through Bluetooth, and transmitting the read music data to the special effect display screen, wherein a plurality of lyric special effect databases are stored in the special effect display screen;
the special effect display screen compares and retrieves data matched with the lyrics and the audio information from the lyric special effect database, and then displays and superimposes the selected special effect form on the lyrics, thereby displaying the special effect lyrics on the special effect display screen.
The music data includes lyrics and audio information.
The specific steps of the special effect display screen comparing and retrieving the data matched with the lyrics and the audio information from the lyric special effect database comprise: detecting the beat of the audio data, and judging whether the detected beat is a rhythm change point of the audio data; if yes, marking the beat as a starting point of the optional music paragraphs, and generating a starting point list, wherein the starting point list comprises a plurality of starting points of the optional music paragraphs; selecting a music paragraph starting point from the starting point list according to a preset starting point selection rule, and dividing the audio data into a plurality of music paragraphs; setting the emotion label of each music paragraph, and calculating the emotion score of the emotion label corresponding to each music paragraph; searching a visual expression effect matched with the emotion scores in a special effect database stored in advance, and storing the identification of the visual expression effect and the music paragraphs in a correlation mode, so that when the audio data are read, the visual expression effect corresponding to the music paragraphs is played.
When the matched audio data is obtained, the audio data may be a specific music file, such as a complete audio data stored in advance, or may be a real-time audio data stream, such as audio data recorded and broadcasted in real time.
The rhythm change point is a time point corresponding to a beat at which the rhythm of the audio data changes, and in concrete implementation, the rhythm change point includes but is not limited to obvious change of sound of musical instruments, obvious change of human voice, obvious change of volume, obvious change of tone and the like.
The emotion labels have three dimensions, such as the speed degree of rhythm, the intensity degree of rhythm points, the extreme emotion product and the like, points are taken in the dimensions at certain intervals, a plurality of labels can be obtained, and the emotion scores can be calculated by setting the corresponding scores of each label.
The step of detecting the beat of the audio data includes: dividing the audio data into equal-length paragraphs according to preset segmentation intervals; calculating the audio energy value of each equal-length paragraph according to the PCM data of the audio data; marking the audio energy value higher than a preset energy threshold value as a peak value, and marking an isometric paragraph corresponding to the peak value as a peak paragraph; acquiring a pre-stored BPM set, and traversing each BPM value in the BPM set from small to large in sequence; calculating the coincidence degree of each BPM value and the peak value distribution; and determining the beat of the audio data according to the BPM value with the highest coincidence degree.
