Sound.setTransform() 637

Mono sounds play all sound input in the left speaker and have the following transform settings

by default:

ll = 100

lr = 100

rr = 0

rl = 0

Example

The following example illustrates a setting that can be achieved by using setTransform(), but

cannot be achieved by using

setVolume() or setPan(), even if they are combined.

The following code creates a new

soundTransformObject object and sets its properties so that

sound from both channels will play only in the left channel.

mySoundTransformObject = new Object;

mySoundTransformObject.ll = 100;

mySoundTransformObject.lr = 100;

mySoundTransformObject.rr = 0;

mySoundTransformObject.rl = 0;

To ap ply t h e soundTransformObject object to a Sound object, you then need to pass the object

to the Sound object using

setTransform() as follows:

my_sound.setTransform(mySoundTransformObject);

The following example plays a stereo sound as mono; the soundTransformObjectMono object

has the following parameters:

mySoundTransformObjectMono = new Object;

mySoundTransformObjectMono.ll = 50;

mySoundTransformObjectMono.lr = 50;

mySoundTransformObjectMono.rr = 50;

mySoundTransformObjectMono.rl = 50;

my_sound.setTransform(soundTransformObjectMono);

This example plays the left channel at half capacity and adds the rest of the left channel to the

right channel; the

soundTransformObjectHalf object has the following parameters:

mySoundTransformObjectHalf = new Object;

mySoundTransformObjectHalf.ll = 50;

mySoundTransformObjectHalf.lr = 0;

mySoundTransformObjectHalf.rr = 100;

mySoundTransformObjectHalf.rl = 50;

my_sound.setTransform(soundTransformObjectHalf);
