本文介绍如何使用Cocos2d-x中的audioEngine进行音频管理，包括创建音频引擎、设置背景音乐及音效音量、播放/暂停/停止音乐等操作，并提供了调整音量、播放效果音等功能的具体实现。

1. 创建audioEngine

audioEngine = cc.audioEngine

2. 设置背景音乐以及音效声音

 // set default volume
        audioEngine.setEffectsVolume(0.5);
        audioEngine.setMusicVolume(0.5);

3. 结束audioEngine

 onExit:function () {
        this._super();
        audioEngine.end();
    },

4. 操作音乐以及动作

var soundId = null;

var playMusic = function () {
    cc.log("play background music");
    audioEngine.playMusic(MUSIC_FILE, false);
};

var stopMusic = function () {
    cc.log("stop background music");
    audioEngine.stopMusic();
};

var pauseMusic = function () {
    cc.log("pause background music");
    audioEngine.pauseMusic();
};

var resumeMusic = function () {
    cc.log("resume background music");
    audioEngine.resumeMusic();
};

var rewindMusic = function () {
    cc.log("rewind background music");
    audioEngine.rewindMusic();
};

// is background music playing
var isMusicPlaying = function () {
    if (audioEngine.isMusicPlaying()) {
        cc.log("background music is playing");
    }
    else {
        cc.log("background music is not playing");
    }
};

var playEffect = function () {
    cc.log("play effect");
    soundId = audioEngine.playEffect(EFFECT_FILE);
};

var playEffectRepeatly = function () {
    cc.log("play effect repeatly");
    soundId = audioEngine.playEffect(EFFECT_FILE, true);
};

var stopEffect = function () {
    cc.log("stop effect");
    audioEngine.stopEffect(soundId);
};

var unloadEffect = function () {
    cc.log("unload effect");
    audioEngine.unloadEffect(EFFECT_FILE);
};

var addMusicVolume = function () {
    cc.log("add bakcground music volume");
    audioEngine.setMusicVolume(audioEngine.getMusicVolume() + 0.1);
};

var subMusicVolume = function () {
    cc.log("sub backgroud music volume");
    audioEngine.setMusicVolume(audioEngine.getMusicVolume() - 0.1);
};

var addEffectsVolume = function () {
    cc.log("add effects volume");
    audioEngine.setEffectsVolume(audioEngine.getEffectsVolume() + 0.1);
};

var subEffectsVolume = function () {
    cc.log("sub effects volume");
    audioEngine.setEffectsVolume(audioEngine.getEffectsVolume() - 0.1);
};

var pauseEffect = function () {
    cc.log("pause effect");
    audioEngine.pauseEffect(soundId);
};

var resumeEffect = function () {
    cc.log("resume effect");
    audioEngine.resumeEffect(soundId);
};

var pauseAllEffects = function () {
    cc.log("pause all effects");
    audioEngine.pauseAllEffects();
};
var resumeAllEffects = function () {
    cc.log("resume all effects");
    audioEngine.resumeAllEffects();
};
var stopAllEffects = function () {
    cc.log("stop all effects");
    audioEngine.stopAllEffects();
};
