Control how sound plays through the right and left speakers

When you want more precise control of how a sound is playing through the left and right speakers, the Sound class in Flash® 8.0 includes the method setTransform(). This method allows you to set percentages that determine how much of the right or left channel plays through the right and left speakers. Using this method, you can make your sound switch speakers from left to right dynamically or switch from stereo to mono. To use setTransform() with the Sound class, you create a generic object and add properties to it that hold the information specifying the distribution of left and right sounds. The properties of the sound transformation object are ll, lr, rr, and rl (Figure 1).

Figure 1: The properties of the object passed to the setTransform() method determine distribution of sounds between the left and right speakers. The first letter refers to the output speaker; the second letter refers to the input sound.
