Dream come true XNA (6)-sound and sound effects

Author: webabcd

Introduction
XNA: Sound and sound effects

• XACT-Cross-platform Audio Creation Tool, a Cross-platform sound production Tool
• SoundEffect-sound object
• MediaPlayer-Media Player Object; Song-music object

Example
1. Use XACT to process and play sound effects (press the K key on the keyboard to load this Demo)
Component/Audio/XACT. cs

/** XACT (Cross-platform Audio Creation Tool)-A Cross-platform sound production Tool for collecting and editing Audio files. XNA provides APIs to play XACT projects. The Reach Standard does not support XACT * 1. XACT can only be processed. audio files in wav format * 2. Microsoft XNA Game Studio 4.0-> Tools-> Microsoft Cross-Platform Audio Creation Tool 3 (XACT3) the XACT editing tool * 3 is enabled. The XACT editing project type is. xap text file (which can be opened in Notepad. xap file and Its referenced. after the wav file is saved to the Content project, Content Pipeline processes it. * 4. Create a Wave Banks (waveform library) and. add the wav file to this library * 5. Create a Sound Banks (audio and audio database). Sound Banks is divided into two windows: Sound Name and Cue Name *) after dragging an Item to Cue Name in Wave Banks, an Item * B will be created in the Sound Name and Cue Name respectively. The number of Sound repetitions can be modified in the Sound Name, volume, high bass, etc. * c) XNA uses the Cue name to play sound effects. A key role of Cue is: A SoundBank object can play multiple Cue * 6 at the same time. If you want to play a sound in the XACT editor, you need to start Microsoft XNA Game Studio 4.0-> Tools-> XACT Auditioning Utility console */using System; using System. collections. generic; using System. linq; using Microsoft. xna. framework; using Microsoft. xna. framework. audio; using Microsoft. xna. framework. content; using Microsoft. xna. framework. gamerServices; using Microsoft. xna. framework. graphics; using Microsoft. xna. framework. input; using Microsoft. xna. framework. media; namespace XNA. component. audio {public class XACT: Microsoft. xna. framework. drawableGameComponent {// audio engine _ AudioEngine; public XACT (Game game): base (game) {} public override void Initialize () {base. initialize ();} protected override void LoadContent () {// Wave Banks (waveform library) object WaveBank waveBank; // Sound Banks (Audio Library) object SoundBank soundBank; /** after compilation, Content Pipeline will. xap files are divided into multiple files as follows: * 1. the xap file will generate a file with the same name. xgs file, which needs to be used when instantiating AudioEngine * 2 ,. each waveform library in xap generates a corresponding one. xwb file.

If you play a new video, you need to instantiate the Cue object * AudioStopOptions. asAuthored-Stop after completing the effect specified by XACT (for example, in this example, Rain is marked as Infinite and Play Release. The former indicates that Rain will Play cyclically, and the latter indicates that it is calling Stop (AudioStopOptions. after AsAuthored), wait until the Rain audio stops playing.) * AudioStopOptions. immediate-Stop now */Cue cueThunder = soundBank. getCue ("Thunder"); System. diagnostics. debug. write (cueThunder. name);} public override void Update (GameTime gameTime) {// AudioEngine. update ()-When each frame is used, the AudioEngine must make some adjustments to the sound under its jurisdiction.

2. Play the sound using SoundEffect (press the L key on the keyboard to load this Demo)
