random sound script

[Trippin13]

Hi
I was hoping if someone could help me write script in F8 that
would play sound on random basis with a fadein and fade out.

Something like people talking in a restaurant which would be too much
as constant ambient noise .. but it would rather from time to time
play in the background ... so that I could mix in few sound clips playing randomly and using small clips I reduce size and make more exciting effect...

any ideas ?

thanks

stuff all of your sounds into an array.. then just call a random sound with setInterval()... you can even set it up to call a random sound, at a random interval of time.... maybe something like this (and i'm just guessing here.. i have no ideas how to stick sounds into an array...):

var sound1 = new Sound();
sound1.attachSound("sound01_ID");
var sound2 = new Sound();
sound2.attachSound("sound02_ID");
var sound3 = new Sound();
sound3.attachSound("sound03_ID");

var mySounds:Array = [sound1, sound2, sound3];

function randomSound(time) {
	wait = time*1000;  // time in seconds...
	go = function () {
		clearInterval(waiting);
		this[random(mySounds[mySounds.length])].start(0, 1);
	};
	var waiting = setInterval(go, wait);
}

randomSound(5);  // 5 = 5 seconds

maybe that'll give you something to work from at least..

I couldn't get this to work at all ?

WEll, i didn't say it work, i said it would give you a place to work from...
But, maybe you want to try this... when i want to use random elements from an array, this is how i do it (and this works just fine with sounds.. i tested it):

// invoking this method will get random elements of the called array

Array.prototype.randomArray = function() {
	var len = this.length;
	var temp = new Array();
	for (var i = 0; i<len; i++) {
		var ran = Math.round(Math.random()*(this.length-1));
		temp[i] = this[ran];
		this.splice(ran, 1);
	}
	for (var j = 0; j<len; j++) {
		this[j] = temp[j];
	}
};

/*
// ------------- EXAMPLE USAGE ------------ >>
var myArray:Array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0];
trace(myArray);
myArray.randomArray();
trace(myArray);
*/


// ---------- FOR YOUR SOUNDS --------->>

// assuming you are creating these sound objects on your _root timeline...
var sound0 = new Sound();
sound0.attachSound("sound00_ID");
sound0.stop();

var sound1 = new Sound();
sound1.attachSound("sound01_ID");
sound1.stop();

var sound2 = new Sound();
sound2.attachSound("sound02_ID");
sound2.stop();

var mySounds:Array = [sound0, sound1, sound2];

// This is the function to randomize the sound array, and play another sound
function randomSound(time) {
	// time in seconds...
	wait = time*1000;
	go = function () {
		stopAllSounds();
		_root.mySounds.randomArray();
		clearInterval(waiting);
		mySounds[0].start(0, 1);
		// call the function again to keep it looping
		randomSound(5);
	};
	waiting = setInterval(go, wait);
}


// start things off...

mySounds[0].start(0, 1);
randomSound(5);   // 5 = 5 seconds

stop();

so there you go.... you'll need to change the linkage ID's in my example to match yours, and adjust the time interval to the number of seconds you want to wait. But otherwise, you shouldn't need to change a thing.
