DirectSound – Playing sound files with DirectX |
This far we’ve only mainly considered the graphical side, together with a little input. Adding sound to a game, however, will greatly improve the overall gaming experience. Playing simple sound files is extremely easy in DirectX. In fact, all you need are 2 variables: again a ‘device’ variable, that will hold the link to the soundcard in your system (which might be integrated into the northbridge of your motherboard), and a buffer to hold the data loaded from the soundfile. So add these 2 variables to the top of your code:
private DS.Device sounddevice;
private SecondaryBuffer shotsound;
A SecondaryBuffer is a buffer where you can add sound effects. Before you can run this, you’ll need to add a new reference to Microsoft.DirectX.DirectSound, or you’ll be getting error messages like ‘The type or namespace name 'SecondaryBuffer' could not be found (are you missing a using directive or an assembly reference?)
‘. We’ll also need to put these lines in our using block:
using Microsoft.DirectX.DirectSound;
using DS = Microsoft.DirectX.DirectSound;
Now we’ll create a method that takes care of all the sound initialisation:
private void InitializeSound()
{
sounddevice = new DS.Device();
sounddevice.SetCooperativeLevel(this, CooperativeLevel.Normal);
BufferDescription description = new BufferDescription();
description.ControlEffects = false;
shotsound = new SecondaryBuffer("shot.wav", description, sounddevice);
shotsound.Play(0, BufferPlayFlags.Default);
}
Now call this method from your Main method and run the program! If your speakers are powered on, you’ll already hear a small shot in the beginning of your program. That’s how easy it is to play a sound effect!
Let’s cycle throught the InitializeSound method. First, we initialize the sound device, and we set the CooperativeLevel to Normal, resulting in easy resource management. To initialize our SecondaryBuffer, we need to provide a BufferDescription, which, well, describes the buffer. If you want to be able to control the volume of the buffer during the game, for example, you’ld have to change to ControlVolume property of this BufferDescription to true. In our case, we will simply turn the ControlEffects to false, which is a requirement is you want to use the Clone method of your SecondaryBuffer, which we will use soon. Then we effectively create the SecondaryBuffer by loading data from the file shot.wav into it. You can find a sample soundfile here (link). The last line actually plays the buffer. The 0 indicates the priority, and Default indicates to only play the sound once, which is the opposite of Looping.
That’s all there is to it! In our case, however, we don’t need the last line, so remove it. We’re going to play the file when a bullet is fired, so go find that piece of code in your ReadUserInput method. Put the line immediately before the line where you subtract 10 points from the score.
When you run this code, you’ll notice the sound will only play when the previous shotsound has ended. This is because 1 buffer cannot be played multiple times at the same time! Another thought would be to Stop() and Play() the sound, but this would give a very odd effect, as you can try.
What we have to do, is to clone our SecondaryBuffer, thus creating a new buffer, that can be played immediately when it’s created. This way, we can have multiple buffers playing simultaneously:
SecondaryBuffer newshotsound = shotsound.Clone(sounddevice);
newshotsound.Play(0, BufferPlayFlags.Default);
This will do the trick! Remember, if your Clone method crashes, this means you have to put the ControlEffects member of your BufferDescription to false, as indicated above.
When you keep firing bullets, your computer will slow down. This is of course because you get a huge amount of buffers stored in your memory! So we need to put all of these buffers in a ArrayList, so we can dispose them from memory when they’re finished. Put this arraylist at the top of your code:
private ArrayList soundlist = new ArrayList();
And immediately under the line where you play your cloned buffer:
soundlist.Add(newshotsound);
This allows you to keep track of all the buffers in memory. We’ll create a very useful method, that will cycle through all of our buffers in memory, and discard those that are finished:
private void SoundAffairs()
{
if (soundlist.Count > 0)
{
for (int i = soundlist.Count - 1; i > -1; i--)
{
SecondaryBuffer currentsound = (SecondaryBuffer)soundlist[i];
if (!currentsound.Status.Playing)
{
currentsound.Dispose();
soundlist.RemoveAt(i);
}
}
}
}
Moving backwards is my favorite way of cycling through an ArrayList. This way, you don’t have to put the i—- when you delete an item, such as we did with our targets. On topic, the method cycles through our soundlist and removes from memory all buffers that don’t have the Playing status. In other words, those that have stopped playing.
Make sure you call this method from within your OnPaint method! Now when you run the program, you can fire as much bullets as you want, without increasing your memory usage.

DirsctSound TV Tuner Help???
Hello ,
I am developoing an application in WPF wh...Microphone input...
Hi!
Is that possible to have Microphone input i...Application crashes
Hello,
Whenever I try run the simple program;
...How mayn Active Buffers?
Hey,
Read your tutorial and it really did help ...
This chapter you’ve learned playing a wav file using DirectX. You should also be able to play it continuously by selecting the Looping property, and you have learned how you can play multiple instances of one SecondaryBuffer simultaneously by using the Clone method, without spilling memory.
Next chapter we’ll be playing sounds in 3D space!
