Problems solved by technology

However, such a display would present an inaccurate picture of the spectral characteristics
In this way, it does not meet the original intention of music visualization, and the synchronization effect of music and pictures is not good, which affects the user experience

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 present invention discloses a music visualization method. The method includes: acquiring a first power spectrum of a first audio frame; A frequency point and a second frequency point; according to a plurality of first frequency points and second frequency points, the first frequency band of the first power spectrum is obtained; the number axis mapping is performed on the second frequency band to obtain the first compressed frequency band, and the second frequency band is less than The frequency range of the minimum frequency point of the first frequency band; the second compression frequency band is obtained by numerical axis mapping to the third frequency band, and the third frequency band is the frequency range greater than the maximum frequency point of the first frequency band; combining the first compression frequency band and the second compression frequency band and the first frequency band to obtain the second power spectrum of the first audio frame. By adopting the embodiment of the present invention, an effective power spectrum display window can be tailored for different music individuation features, so that the music visualization effect is more in line with human hearing.

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 ...
