How to embed and play a .wav file in Windows Phone 7 app

Hamishwillee - Minor subedit

Hi Vaishali

I've deleted my previous comment - sorry, it wasn't very useful. I've also subedited this for wiki style and a little for English

I think this is quite nicely done. In particular I like how you haven't put images for the "obvious" stuff like selecting the application template, but have shown them where needed.

In terms of improvements, I'd suggest:

1. Add a zip file with a buildable version of the project in a zip file - this will allow people to try out the code, knowing it worked in at least one version.
2. Link to other related resources. For example, API reference for StreamResourceInfo, SoundEffect, SoundEffectInstance. If there are any articles you used to work out how to do this - ie playing media files overview on MSDN, then these could also be linked in a "SeeAlso"
3. It would also be excellent if there was a brief explanation of what is going on here - for example what setting Build Action to resource actually does, how the streaming classes work, how playing works.

Getting started

First create a Windows Phone application.

• Open Visual Studio and select Windows Phone Application from the installed templates. Here I have named the application "Age Calculator".
• Select Windows Phone 7.1 as the Target Version.
• Right-click on the “References” in the project and click “Add Reference…”. Find the “Microsoft.Xna.Framework” reference and add it to the project.

Adding a reference to a project

Selecting a particular framework reference

Adding the WAV file to project resources

Next add the WAV File to the project resources:

• Right-click on the project and add new folder. Name the folder -

here I have used the name "Sound".

• Right-click on the Sound folder and select Add existing items. Add the WAV file to this folder.

• After adding WAV file select the file and right-click and open Properties and change the “Build Action” to “Resource”

Code to play embedded WAV file

• Add the following namespace to the MainPage.xaml.cs file

using System.Windows.Resources;
using Microsoft.Xna.Framework;

• Code to play the .wav file

void Play_wavFile(object sender, EventArgs e)
 {
              StreamResourceInfo _stream = Application.GetResourceStream(new Uri("/AgeCalculator;component/Sound/BirthdayTune.wav", UriKind.Relative));
              SoundEffect _soundeffect = SoundEffect.FromStream(_stream.Stream);
              SoundEffectInstance soundInstance = _soundeffect.CreateInstance();
              FrameworkDispatcher.Update();
              soundInstance.Play();
}

• To play the wav file on a button press

Private void button1_Click(object sender, RoutedEventArgs e)
  {
      Play_wavFile();
  }

• Now build the project and run it using F5.

On Button click, .wav sound file start playing.
