手游中的声音处理

手游中的声音处理

本文是在同一个游戏中移植在不同机型时所做的对声音的处理，考虑到性能的要求，对每种类型的手机做了一定的要求

s40 中的声音处理：

1) kia.mid.sound.*;

2)

Sound soundPlayer;
void initSound(){
soundPlayer = new Sound(b_main,1);
if(m_playSound == 1){
soundPlayer.play(0);
}
}

3)
byte[] b_main = {
(byte)0x02,(byte)0x4a,(byte)0x3a,(byte)0x40,
(byte)0x04,(byte)0x01,(byte)0x1f,(byte)0x1e,
(byte)0x54,(byte)0x88,(byte)0x38,(byte)0x84,
(byte)0x44,(byte)0xbc,(byte)0x4a,(byte)0xc4,
(byte)0xa0,(byte)0xa9,(byte)0x0b,(byte)0x91,
(byte)0x27,(byte)0x22,(byte)0xa2,(byte)0xb1,
(byte)0x31,(byte)0x13,(byte)0x88,(byte)0x00,
};

4)
static int m_playSound = 1;

5) 在程序中对声音的控制
m_playSound = (byte)(1 - m_playSound);
if(m_playSound == 1){
try{
soundPlayer.play(0);
} catch(Exception e){}
}
if(m_playSound == 0){
try{
soundPlayer.stop();
} catch(Exception e){}
}

手游账号买卖平台使用 ott 文件 在nokia 40或 60中

1) 定义数据结构
public class EMSound
{
public int type;
public byte[] data;

public EMSound(byte[] data, int type)
{
pe = type;
this.data = data;
}
}

2)
kia.mid.ui.*;
kia.mid.sound.*;
3)
Sound soundPlayer;
SoundListener soundListener = new EMSoundListener();


EMSound currentSound = null;
boolean soundPlaying = false;
boolean soundEnable = true;

class EMSoundListener
implements SoundListener {
public void soundStateChanged(Sound sound, int event) {
switch (event) {
case Sound.SOUND_STOPPED:
soundPlaying = false;
break;
case Sound.SOUND_PLAYING:
soundPlaying = true;
}
}
}

public EMSound loadSound(String resfile, int resID) {
EMSound sound;
try {
InputStream is = getClass().getResourceAsStream(resfile + "/" + resID +
".ott");
int len = (int) is.skip(10000);
is.close();
is = getClass().getResourceAsStream(resfile + "/" + resID + ".ott");
byte[] barr = new byte[len];
is.read(barr);
is.close();
sound = new EMSound(barr, Sound.FORMAT_TONE);
}
catch (Exception ex) {
sound = null;
}
return sound;
}
