  1. XNA Basic XACT tool

  2. What’s format song file which XNA support? • Only .wav because it’s not compress file. • Beside, you need XACT project ( XACT project) which XNA can include.

  3. Audacity • It’s a free ware. You can use it for catching songand exporting format which you want. • Download : http://audacity.sourceforge.net

  4. XACT tool • XACT tool is concurrence being installed with XNA.

  5. Starting with XACT • How do we start? • First .wav file should be in content folder. • Second create new project from file menu. • Third create Wave Bank from Wave Bank menu. • Forth drag drop .wav file into Wave Bank windows or choose insert file from Wave Bank menu.

  6. Starting with XACT • 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.

  7. 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.

  8. Audio Engine, Wave Bank, Sound Bank • Audio Engine tell XNA about setting in XACT project. • Wave Bank tell XNA about its settingand which file hold data. • Sound Bank is the same Wave Bank doing.

  9. 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.

  10. 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”) }

  11. protected override void update() { sounds.PlayCue(“scream”); } Cue name in your project

  12. 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();

  13. Let’s practice more • Use your project from getting input, Make it have sound effect.
