Only .wav because it’s not compress file.

How do we start?

Fifth drag drop .wav file from Wave Bank
window into Sound Bank up window.
Sixth drag drop .wav file from Sound Bank up
window into down window for creating Cue.
Seventh build and save project.
When build project, it will create .xgs
file(Audio Engine), .xwb file(Wave Bank),
.xsb(Sound Bank) which we will talk late.
Why must we have Wave Bank and
Sound Bank?



Wave Bank is a material for creating Sound
Bank.
Two Wave Bank can create many Sound
Bank.
But we won’t talk detail about it because it’s
job of sound engineer. You can find more
detail in wiki.
Audio Engine, Wave Bank, Sound Bank



Audio Engine tell XNA about setting in XACT
project.
Wave Bank tell XNA about its setting and
which file hold data.
Sound Bank is the same Wave Bank doing.
Include XACT project.

Right click at content in Solution Explorer and
choose exiting item and find .xap file (XACT
project)
Don’t forget .wav file must be in content
folder.
It’s good at everything being in new folder.
Here I’ll create folder Sound.
Sample Code for loading XACT
AudioEngine audio;
WaveBank waves;
SoundBank sounds;
protected override void LoadContent()
{
audio = new
AudioEngine(@”Content\Sound\SampleSound.xgs”)
waves = new WaveBank(audio,@”Content\Sound\Wave
Bank.xwb”)
sounds = new
Sound(audio,@”Content\Sound\SoundBank.xsb”)
}
protected override void update()
{
sounds.PlayCue(“scream”);
}
Cue name in your project
Or maybe you may use cue instead of
Sound Bank.
Cue SoundCue;
SoundCue = sounds.GetCue(“scream”);
You can use
SoundCue.IsPlaying;
SoundCue.IsPaused;
SoundCue.Play();
SoundCue.Pause();
SoundCue.Resume();
Let’s practice more

Use your project from getting input, Make it
have sound effect.
