Using FMOD for C#?

Question

I'm working with FMOD in C#. I've tried importing the fmodex.dll file by selecting Project->Add Reference and browsing for the fmodex.dll, but I am getting an error:

A reference to ... could not be added. Please make sure that the file is accessible, and that it is a valid assembly or COM component

It is accessible, but I still get the error. I read the guide and it says to use the fmodex_vc.lib when linking to the fmodex.dll file. So I try, but I can't seem to find on how to link to .lib files in Visual Studio; searching Google always leads me to linking to .dll files.

Answer 1

Fmod is written in unmanaged C++ so you cannot reference it directly from a .Net application. There is a c# wrapper to the fmodex.dll in the fmod package under a directory called "fmod_wrapper" if I am not mistaken that you can add to your project and which will take care of making the P/Invoking for you.

Try https://github.com/madrang/FmodSharp been working for a little while on it. It should be better than the current Fmod wrapper.

Instead of using Handles and coding like you are using C++ in C#. The FmodSharp wrapper is object oriented and there is no need to think about using handles.

public static void Main (string[] args)
{
    Console.WriteLine ("Fmod Play File Test");

    Xpod.FmodSharp.Debug.Level = Xpod.FmodSharp.DebugLevel.Error;
    var SoundSystem = new Xpod.FmodSharp.SoundSystem.SoundSystem();

    Console.WriteLine ("Default Output: {0}", SoundSystem.Output);

    SoundSystem.Init();
    SoundSystem.ReverbProperties = Xpod.FmodSharp.Reverb.Presets.Room;

    if (args.Length > 0) {
        foreach (string StringItem in args) {
            Xpod.FmodSharp.Sound.Sound SoundFile;
            SoundFile = SoundSystem.CreateSound (StringItem);

            Xpod.FmodSharp.Channel.Channel Chan;
            Chan = SoundSystem.PlaySound(SoundFile);

            while(Chan.IsPlaying) {
                System.Threading.Thread.Sleep(10);
            }

            SoundFile.Dispose();
            Chan.Dispose();
        }

    } else {
        Console.WriteLine ("No File to play.");
    }

    SoundSystem.CloseSystem();
    SoundSystem.Dispose();
}

In order to use FMOD in C# you need to wrap FMOD functions and structures using p/Invoke. This task has been taken care of for you in the open source project fmodnet

Answer 4

To add a COM item to a VS project perform the following steps:

• Register the COM

• Select "Add Reference"

• Select COM tab

• Browse to item and select it.

You should see (after a build) that VS has created an Interopt DLL library in your BIN dir.
