Since I’ve never tried monkeying with computeSpectrum to analyze audio data, I figured that would be a fun place to start before launching into the Flash Player 10 dynamic audio APIs. I applied the ‘vumeter’ effect to a song’s music video, slicing the frames into vertical strips and shifting them based on the amplitude of the frequency. The shifting amount is variable based on mouse Y position. This looked nice when applied to videos with a main focal image and a plain background, on my wife’s suggestion I wound up using the song Colors by Utada Hikaru, Japan’s favorite Tetris playing pop star.
