In our case, we will be representing the values of the FFT with the heights of various cubes. Music visualizations are nothing more than visual representations of the FFT for a song and how it changes over time. You might have noticed the FFT graph looks a little bit like a music visualization - and in fact it is. The leftmost peak represents the lowest frequency (the bass), and is the tallest because the bass has the greatest amplitude out of the four waveforms. You’ll notice there are 4 peaks, one for each of the pure waveforms. Performing FFT on the result returns an array of weights, which represent how much of each base frequency is being used in the result. What you physically hear is the result, which is the sum of the pure bass, kick, synth, and harmonics waveforms. Take the picture below as an example, which looks at a simple song from various perspectives. The Fast Fourier Transform algorithm is the exact reverse - it takes a complex waveform and decomposes it into its base frequencies. This complex waveform is then processed by your brain to create music, conversation, and everything else you hear. Pure waveforms from various sources combine together into a single complex waveform. Links: 1, 2, 3, 4, 5.Įvery sound that enters your ear is actually a sum of different frequencies. This homework only goes over the basics, but you could take it to another level by adding your own flair. In the meantime, take a look at these amazing music visualizer examples created with Unity by other people. Create a new scene called HW2 to work in.
Unity music visualizer download download#
This assignment will be a review of some of the Unity editor tools you have practiced in HW1, but more importantly, an introduction on using C# scripts to manipulate gameobjects.įirst off, download the skeleton asset package here and import it into a new project.
Your second assignment is to create your very own music visualizer! It will look something like this:
