CodeProject: A simple class to allow you to play Wavs in C#. Free source code and programming help

The tonysound.cs class gives you the ability to add Wav sound to your Windows forms. Simply include the tonysound.cs in your project folder. This is my first article, so please don't beat me up too bad.

Including the code in your form

Add the tonysound.cs file to your project. Then at the top of the calling form, for example, form1, type the following line to use the tonysound class.

Note: You can pass as many flags as you want, but if you're playing a file then you need to do something like I have in my code:

The first parameter of Sound.Play is the filename. The filename can be the actual path, for example c:\\sound.wav, or it can simply be a Wav file that is in the same directory as the exe. The second is the flag for playing the sound. You can play a null sound to turn off the sound as follows:

NOTE: You must include either PlaySoundFlags.SND_FILENAME or PlaySoundFlags.SND_RESOURCE in order to actually play the song. The remaining flags are optional.

Alternative - using sound recorder to play wave file programmatically

Just an FYI to those interested. I just found this out from a web search. Launch a process in .NET to run the following command: sndrec32 /play /close pathToWaveFile "A good scientist is a person with original ideas.

Use of tony sound library fails to work after compiling

daluu

15:23 19 Jul '07

Has anybody encountered this? I'll probably have to try compiling on other computers to see what happens.

I made use of tony sound library per instructions in the article. After compilation, it fails to play wave file. I get silence. It's even worse on console applications, it hangs trying to play the wave file.

I originally used it for a console application (built with SharpDevelop 2.0). When that didn't work, I tried the same thing on Visual Studio 2003. When that didn't work, tried builing a GUI app on Visual Studio 2003. When that didn't work, tried using the provided demo application and source files to test.

The demo ran fine. The source ran fine after compiling. Modified the source to play a different wave file, and that worked too.

My system is running Windows XP SP2, with .NET v1.1, v2.0, Visual Studio 2003, SharpDevelop 2.0. I verified I have winmm.dll on my system as well.

My code is roughly the same as the provided demo, I have no idea what the heck's going on. I wish the compile would fail with an message or that the running the app would give a runtime error. Too bad all it does is "nothing" or hang. Guess I'll try analyzing with a debugger when I have some time.

btw, be nice if someone could compile a console app that takes an argument for the path to a wave file to play. That's what I was originally trying to do.

Other than .wav files

J.S.Lim

hi, i found out that this program does not support other audio files other than .wav files. Do you have anything that allows the application to play other audio formats such as MP3s or WMAs?

Please tell me what do these flags? Where do you find information about them?

liubomir

20:38 4 Jun '05

          SND_SYNC = 0x0000, /* play synchronously (default) */
          SND_ASYNC = 0x0001, /* play asynchronously */
          SND_NODEFAULT = 0x0002, /* silence (!default) if sound notfound */
          SND_LOOP = 0x0008, /* loop the sound until nextsndPlaySound */
          SND_NOSTOP = 0x0010, /* don't stop any currently playingsound */
          SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
          SND_FILENAME = 0x00020000, /* name is file name */
          SND_RESOURCE = 0x00040004 /* name is resource name or atom */
I want to understand these flags and to add more usefull in my programs. In many of my programs i need to pause wave sound for example.

look at http://republika.pl/dailybuilds/waveform.html

As you asked you should look forward to Platform SDK at www.microsoft.com - see msdn section and download Platform sdk, there is all that stuff about win32 API and libraries with full documentation

Consider these changes

Mark Pitman

I took a look at your code and I have some suggestions. I rewrote your tonysound.cs class like so:


using System;
using System.Runtime.InteropServices;

namespace tonysound {
	public class Sound {
		public static void Play( string strFileName, PlaySoundFlags soundFlags) {
			PlaySound( strFileName, IntPtr.Zero, soundFlags);
		    
		}

		[DllImport("winmm.dll")] //inports the winmm.dll used for sound
		private static extern bool PlaySound( string szSound, IntPtr hMod, PlaySoundFlags flags );
	}

	[Flags] //enumeration treated as a bit field or set of flags
	public enum PlaySoundFlags: int {

		SND_SYNC = 0x0000, /* play synchronously (default) */
		SND_ASYNC = 0x0001, /* play asynchronously */
		SND_NODEFAULT = 0x0002, /* silence (!default) if sound notfound */
		SND_LOOP = 0x0008, /* loop the sound until nextsndPlaySound */
		SND_NOSTOP = 0x0010, /* don't stop any currently playingsound */
		SND_NOWAIT = 0x00002000, /* don't wait if the driver is busy */
		SND_FILENAME = 0x00020000, /* name is file name */
		SND_RESOURCE = 0x00040004 /* name is resource name or atom */		
	} 
}

then to call the Play method you would do something like this:

Sound.Play("sound.wav", PlaySoundFlags.SND_FILENAME | PlaySoundFlags.SND_ASYNC | PlaySoundFlags.SND_LOOP | PlaySoundFlags.SND_NOSTOP);

There are a few reasons to implement these changes. You don't have to know what strings to pass in to the Play method, you don't have to pass any more flags in than you actually need, and you don't have to do string comparisons (yuck!).

Thanks.
You have a very good point about the string comparison part. I never even thought about it that way. I will change the source code to make these changes for I actually like it better myself. This is one of the main reasons I posted this article. So I can learn how to make my code better from individuals like yourself and also share something useful to others.

Thanks again. When I get a chance I will recompile test and update my version on here. It shouldn't be any later than tonight.

You can tell I'm new at this but hey we all start somewhere Laugh
