Till now, all methods for simulate 2D water ripples that I found in actionscript, are based on the same principle.
A simple and relatively fast algorithm, that I found here.
The base of this algorithm, is the relation between the speed of the wave and their previous values of position. For that, we need to store the last two states of the water in two arrays.
After seeing what some speakers are doing at the FITC in San Francisco, I decided it was time to use flash to play with sound.
First of all, lets understand how does sound works taking one of the simplest sound forms, a note, represented by a sine wave.
