Sounds use a considerable amount of disk space and memory. Because stereo sounds use twice
as much data as mono sounds, it is generally best to use 22-KHz 6-bit mono sounds. You can
use
setTransform() to play mono sounds as stereo, play stereo sounds as mono, and to add
interesting effects to sounds.
Note: Flash Lite 2.0 supports this method for native Flash sound only. The sound formats
that are specific to a host device are not supported.
The properties for the
soundTransformObject are as follows:
11 - A percentage value that specifies how much of the left input to play in the left speaker (0-
100).
1r - A percentage value that specifies how much of the right input to play in the left speaker
(0-100).
rr - A percentage value that specifies how much of the right input to play in the right speaker
(0-100).
rl - A percentage value that specifies how much of the left input to play in the right speaker
(0-100).
The net result of the parameters is represented by the following formula:
leftOutput = left_input ~ ll + right_input ~ lr
rightOutput = right_input ~ rr + left_input ~ rl
The values for left_input or right_input are determined by the type (stereo or mono) of
sound in your SWF file.
Stereo sounds divide the sound input evenly between the left and right speakers and have the
following transform settings by default:
ll = 100
lr = 0
rr = 100
rl = 0
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

class.
