Thread: Getting some sound in your DX games

Here is some intro code for you. Just got my book on directx 9 audio programming (3D math book is now on the way) and it has taught me a lot about audio programming and much about music synthesis, tracks, segments, etc.,etc. Very good book.

Here is some code to get you up and running.

Code:

IDirectMusicPerformance8 *pPerformance=NULL;
IDirectMusicLoader8 *pLoader=NULL;
IDirectMusicSegment8 *pSegment=NULL;

//
//Init COM
//
CoInitialize(NULL);

//
//Create loader
//
CoCreateInstance(CLSID_DirectMusicLoader,
                              NULL,
                              CLSCTX_INPROC,
                              IID_IDirectMusicLoader8,
                              (void **)&pLoader);

//
//Create Performance
//
CoCreateInstance(CLSID_DirectMusicPerformance,
                              NULL,
                              CLSCTX_INPROC,
                              IID_IDirectMusicPerformance8,
                              (void **)&pPerformance);

//
//Init performance
//
pPerformance->InitAudio(NULL,
                                         NULL,
                                         NULL,
                                         DMUS_APATH_DYNAMIC_STEREO,
                                         2,
                                         DMUS_AUDIOF_ALL,
                                         NULL);

//
//Load WAVE from current directory
//assumes "anywavefile.wav" is file name
if (SUCEEDED(pLoader->LoadObjectFromFile(
                                       CLSID_DirectMusicSegment,
                                       IID_IDirectMusicSegment8,
                                       L"anywavefile.wav",
                                       (LPVOID *)&pSegment))) {}

//
//Place wave data in synth
//
pSegment->Download(pPerformance);

//
//Finally, play the thing
//
pPerformance->PlaySegmentEx(
                                                  pSegment,
                                                  NULL,
                                                  NULL,
                                                  0,
                                                  0,
                                                  NULL,
                                                  NULL,
                                                  NULL);

//Pause for sound to play
//Insert code here


//
//Unload data
//
pSegment->Unload(pPerformance);

//
//Release segment from memory
//
pSegment->Release();

//
//Close down performance and release
//
pPerformance->CloseDown();
pPerformance->Release();


//
//Release loader
//
pLoader->Release();


//
//Done with COM
//
CoUninitialize();

Requires DirectX 9.0 and MSVC version 6.0+
