Using the microphone – part 2

This is really simple:

1
2
3
4
5
6

mic = Microphone.get()
attachAudio(mic)
mic.setUseEchoSuppression(false)
onEnterFrame = function(){
	object._xscale = object._yscale = mic.activityLevel
}

Sometimes the activity level is a bit low and so you could just:

1

object._xscale = object._yscale = mic.activityLevel+100

or

1

object._xscale = object._yscale = mic.activityLevel*2

6

mic = Microphone.get()
attachAudio(mic)
mic.setUseEchoSuppression(false)
onEnterFrame = function(){
	object._xscale = object._yscale = mic.activityLevel*10
}

produces:

Sound – part 2

Yesterday i published part one with the basic syntax… Now i bring you part two.

In this tutorial i will show you how to fade i sound, you could duplicate and edit it to allow fade out too if you needed…

So, here is my function

1
2
3
4
5
6
7
8
9
10
11
12
13
14

function fadeInSound(fileID,nameID,speed){
	nameID = new Sound(_root)
	nameID.attachSound(fileID)
	nameID.start()
	nameID.setVolume(0)
	checkFadeIn = setInterval(fadeInSoundCheck,speed,nameID)
}
function fadeInSoundCheck(nameID){
	if(nameID.getVolume()<100){
		nameID.setVolume(nameID.getVolume()+1)
	}else{
		clearInterval(checkFadeIn)
	}
}

Line 1 : Declares the function with three parameters
Line 2 – 5 : Uses the basic syntax to setup the sound object
Line 6 : Passing the parameters through an interval, so we can control the speed of the sound fade
Line 8 : Uses the parameters passed through the function to use again
Line 9 – 12 : If it isn’t at max volume then increase the sound, otherwise remove the interval

For example

1

fadeInSound("SomeSoundID","SomeSoundsNewID",100)

Sound – part 1

Sound

Does a great game have background music? Yes
Does a great game have sound effects? Yes
Does a great game NEED sound? Yes

So, here goes…

I recently decided that sound would make a good tutorial. In this short tutorial i will only show you the basic syntax, tomorrow i will use some custom functions which allow me to modify the sond; eg fade in, pan etc…

So… The code

1
2
3
4
5

SoundName = new Sound (_root)
SoundName.attachSound("SoundID")
SoundName.start(StartPos,Loops)
SoundName.setVolume(50)
SoundName.setPan(-50)

Firstly, make sure that the sound is in Flash’s library.
Then, right click it and export it for actionscript. Note down the identifier, so we can access it later…

Line 1 : Creates a new sound object attached to the root.
Line 2 : Attaches the actual sound file to the object (SoundID = identifier)
Line 3 : Starts the sound, Where to start from and how many times to loop
Line 4 : Set’s the volume of the sound object (100 = max)
Line 5 : Set’s the pan of the sound object (0 = center, -100 = left, 100 = right)
