The concept of the whole work is to combine the rhythm of the music to create different visual visual effects, using the lines and the rhythm of the music to simulate the beat. Through the movement design of particles, the feeling of time and space travel is created, and the interstellar atmosphere of the universe is created. The black background has a sense of cosmic depth, and the stars use white particles to create resizing to create a three-dimensional sense of space.

Process Thinking

​

Create a function name preload() and add the mp3 file to read the song, play the song in setup() and get its amplitude, listen to all p5sound by default, or use setInput() to listen to a specific sound source. Use beginShape( ) to start recording the vertices of the shape and endShape( ) to stop recording. After visualization the P5.FFT object can return an array based on the analysis of FFT.waveform( ) and FFT.analyze( ): Each value computed along the time domain by FFT.waveform() represents the amplitude of the waveform at that time sample. Each value computed by FFT.analyze() along the frequency domain represents the magnitude at that slice of the spectrum.
