for ループ内で倍数関数を作成できますか?

var mySound1 = new buzz.sound( "laser-01", { formats: [ "ogg", "mp3", "acc" ]});
var mySound2 = new buzz.sound( "alien-noise-01", {formats: [ "ogg", "mp3", "acc" ]});

var sound = [mySound1, mySound2]

// additional sounds
var $i;
for ( $i = 0; $i< sound.length; $i++){
    function playsound[$i](){   
           a[$i].play().fadeIn().loop();
        }
}

playsound1();

関数を再利用できます:

// declare your sound dictionary
var sounds = {
    'laser':       new buzz.sound( "laser-01", { formats: [ "ogg", "mp3", "acc" ]}),
    'alien-noise': new buzz.sound( "alien-noise-01", {formats: [ "ogg", "mp3", "acc" ]})
};

// this is the helper function
var playSoundFn = function() {
    this.play().fadeIn().loop();
};

// assign the helper function to all your sounds
for (var i=0, len=sounds.length; i<len; i++){
    sounds[i].playSound = playSoundFn;
}


// then play your sounds from any of them in your dictionary :
sounds['laser'].playSound();
sounds['alien-noise'].playSound();

**編集** ( TheSmoseに感謝)

sounds配列内の各項目がbuzz.sound.prototypeプロトタイプで作成されている場合は、カスタム関数を単純に追加して使用できます。

// this is the helper function
buzz.sound.prototype.playSound = function() {
    this.play().fadeIn().loop();
};

// declare your sound dictionary
var sounds = {
    'laser':       new buzz.sound("laser-01", { formats: ["ogg", "mp3", "acc"]}),
    'alien-noise': new buzz.sound("alien-noise-01", {formats: ["ogg", "mp3", "acc"]})
};

// then play your sounds from any of them in your dictionary :
sounds['laser'].playSound();
sounds['alien-noise'].playSound();

$i をパラメータとして、playsound 関数に渡すだけのほうがよいでしょう。

var sounds = [
    new buzz.sound( "laser-01", { formats: [ "ogg", "mp3", "acc" ]}),
    new buzz.sound( "alien-noise-01", {formats: [ "ogg", "mp3", "acc" ]})
];

var playsound = function (i) {   
   sounds[i].play().fadeIn().loop();
}

playsound(1);

スタイル関数名が本当に必要な場合はplaysound1()、それを評価できます (ただし、これを追加しないことをお勧めします)。

for (var i = 0; i < sounds.length; i++){
    eval('var playsound' + (i+1) + ' = function() { playsound(' + i + '); };');
}

playsound1();
playsound2();
