All we need to do is to create a folder for the audio. Right click on the project and select 'New Folder' name the folder 'Audio'.

GameStudioExpressNewFolder.png

Now copy at least one 44,100 Hz wav file to the folder to use in the test project. You can do this in windows.

Now we can use XACT http://msdn2.microsoft.com/en-us/library/bb174772.aspx

XACT Time

Open XACT

XACTOpen.png

Add a new WaveBank. Wave Banks hold a collection of sound files.

XACTNewWaveBank.png

Now create a new Sound Bank. A Sound Bank is a collection of Events, Tracks and Cues.

XACTNewSoundBank.png

I like to tile the XACT windows horizontally

XACTTile.png

Now we can import sound files.

XACTReadyForImport.png

Select Wave Bank and Import Files or right click on the Wave Bank Window and select Import Wave.

XACTNewSound.png

Now we have a sound in the Wave Bank we need to add it to the Sound Bank. Drah the sound from the Wave Bank window to the Sound Bank window.

XACTDragFromWaveBank.png

Now that the sound is in the Sound Bank we need to add it as a Cue. Drag the sound from the Sound Bank to the Cue section.

XACTDragFromSoundBank.png

Now you should have the sound in all three sections.

XACTCueCreated.png

Now we have a sound in the Wave Bank and Sound Bank and a Named Cue we are ready to save our XACT project. Save the project as 'sound1.xap' in the 'Audio' folder that you created in the Game Studio Express Project.

XACTSaveAs.png

The last step is to build the XACT project to the GSE and integrate it into the game pipeline. Select build from the File menu in XACT.

Import into GSE

Time to Code

Now we need to add the code to the project to play the sound


public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        ContentManager content;


        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            content = new ContentManager(Services);
        }

add

 //Declare Audio Objects
       public AudioEngine engine;
       public WaveBank wavebank;
       public SoundBank soundbank;
public class Game1 : Microsoft.Xna.Framework.Game
    {
        GraphicsDeviceManager graphics;
        ContentManager content;

        //Declare Audio Objects
        public AudioEngine engine;
        public WaveBank wavebank;
        public SoundBank soundbank;


        public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            content = new ContentManager(Services);

now add to the constructor

//initalize Audio Objects
           engine = new AudioEngine(@"Audio\sound1.xgs");
           wavebank = new WaveBank(engine, @"Audio\Wave Bank.xwb");
           soundbank = new SoundBank(engine, @"Audio\Sound Bank.xsb");


public Game1()
        {
            graphics = new GraphicsDeviceManager(this);
            content = new ContentManager(Services);

            //initalize Audio Objects
            engine = new AudioEngine(@"Audio\sound1.xgs");
            wavebank = new WaveBank(engine, @"Audio\Wave Bank.xwb");
            soundbank = new SoundBank(engine, @"Audio\Sound Bank.xsb");
        }

and finally add to the update method

//Play Sound
soundbank.GetCue("FlameWhooshBy").Play();
protected override void Update(GameTime gameTime)
        {
            // Allows the default game to exit on Xbox 360 and Windows
            if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed)
                this.Exit();

            // TODO: Add your update logic here

            base.Update(gameTime);

            //Play Sound
            soundbank.GetCue("FlameWhooshBy").Play();
        }

Now you can test you game by running the project (press F5) or
