Inspiration
I wanted to visualize some music, but I actually had no clue where to start.
What it does
It takes in a stream of audio (using PyAudio) and it applies a Fast Fourier Transformation algorithm to the stream (using a modified built-in from Numpy), which processes the audio and represents it visually on a Pygame GUI.
How I built it
I used Pyaudio, the numpy/scipy suite and Python for the data processing part, and the front-end Pygame.
Challenges I ran into
It was so hard. It was just simply hard. I had to learn the details for a fourier transformation without a solid background in linear algebra, which was absolute nuts.
Accomplishments that I'm proud of
But in the end, everything worked out just fine. A lot of Googling and a lot of textbook flipping, I finally understood the Fourier Transformation algorithm and got the program to work.
What I learned
With dedication (and Google haha), anything will work in the end!
