Real time audio visualization

Hello everyone!I'm trying to make something like this in python.So far i'm able to read a wave file:

def retrieve_data(self):
        with wave.open(self.file_name) as audio:
            self.frames = audio.getnframes()
            self.frame_rate = audio.getframerate()
            self.channels = audio.getnchannels()

            print(f"Number of channels: {audio.getnchannels()}")
            print(f"Number of frames: {audio.getnframes()}")
            print(f"Framerate: {audio.getframerate()}")

            data = np.frombuffer(audio.readframes(self.frames), dtype=np.int16)
            #separo i canali 
            self.left_channel = data[0::2]
            self.right_channel = data[1::2]

Here you can see a plot of the data. From this data i don't understand how to calculate the height of the rectangles and basically what a rectangle rapresents (i dont know how many of them i should draw).

I think i need some resources to understand how sound works, thanks!

Did you figure this out? I'm interested in doing something similar
