I have always been fascinated by music visualization plugins such as milkdrop and I've decided to start a project doing something similar in LabVIEW. I started by taking the example VI that converts a .wav file to a waveform and plays the waveform. After extracting one channel from the waveform, I loaded the information into an array and converted the array to an image. I then resampled the image to the screen size. The result is very interesting, it looks like a bar code whose bars swell, intensify and fade in tune with the music.
Naturally, I want to take this further. More advanced matrix operations could probably yield some interesting results. I've alslo experimented with applying bandpass filters to the song to make the visualization only react to the bass or guitar part. I'll post a pic of the VI and the visualization image after my morning trip to starbucks is over.
