Embodiment Construction

[0056] The technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings.

[0057] See figure 1 , figure 1 It is a schematic diagram of the network architecture of a music visualization system provided by an embodiment of the present invention.

[0058] Such as figure 1 As shown, the network architecture of the music visualization system may include a device 101 for sending target audio and a music visualization device 102 .

[0059] The device 101 for sending target audio can be any device capable of processing original audio data and converting it into a digital signal that can be processed by a computer, and the digital signal can be called target audio. The device 101 for sending target audio may be, but not limited to, an audio device such as a sound card.

[0060] Such as figure 1 As shown, the device 101 for sending target audio can be connected to the Internet to obtain original audio data, or c...

Abstract

The embodiment of the invention discloses a music visualization method. The method comprises the following steps: acquiring a first power spectrum of a first audio frame; determining a plurality of first frequency points and second frequency points of the first power spectrum according to power spectrum data of each frequency point in the first power spectrum; obtaining a first frequency band of the first power spectrum according to the plurality of first frequency points and the second frequency points; performing number axis mapping on a second frequency band to obtain a first compressed frequency band, wherein the second frequency band is a frequency range smaller than a minimum frequency point of the first frequency band; performing number axis mapping on the third frequency band to obtain a second compressed frequency band, wherein the third frequency band is a frequency range greater than the maximum frequency point of the first frequency band; and combining the first compressedfrequency band, the second compressed frequency band and the first frequency band to obtain a second power spectrum of the first audio frame. By adopting the embodiment of the invention, an effectivepower spectrum display window can be customized for different music according to personalized characteristics of the different music, so that the music visualization effect better conforms to the listening feeling of human ears.

Description

technical field [0001] The present invention relates to the field of visualization, in particular to a music visualization method, device and system. Background technique [0002] In the traditional sense, music belongs to the art of experiencing beauty through hearing. But music also has the characteristics of image thinking. Accompanied by emotions, through imagination and association, images such as music images, life scenes, and artistic conceptions are obtained, and music visualization becomes reality. Music visualization refers to extracting the features of audio signals such as music, and then expressing the audio features through image rendering, so that the picture changes with the music. That is to use image language to explain the feeling of music. [0003] Existing music visualization processing technologies can include content analysis and feature extraction of natural audio (such as audio in WAV, MP3 and other formats). Common extraction methods include Fast ...
