Visualizing Sound Data Mastering any language depends heavily on motivating yourself to practice it. This is especially true with programming languages, because code is difficult to work into day-to-day conversation. Finding as little as 15 minutes a day to experiment with ActionScript 3.0 will hasten your progress considerably, however, and visualizing sound data will make that practice time fly by. ActionScript 3.0 gives you access to raw sound data during playback, allowing you to synchronize visuals to amplitude or frequency spectrum information. Using the former, you might easily create peak meters, or animated speaker illustrations, that bounce or throb to the beat. With spectrum data, on the other hand, you can draw a waveform of the sound or depict the low-, mid-, and high-range frequency bands of a sound much like an equalizer display.
