Welche Fmod Version verwendest du?

Ich habe den code mit der fmod v3.73 getestet.

Hier der ganze Code (ist nur en Test)!

Code:
unit CommonTypes;

interface
 uses Windows, fmod, fmodtypes;

  Type TEqPreset = array [0..9] of Integer;
  Type TWaveData = array [0..2048] of DWORD;
  Type TFFTData = array [0..512] of Single;

  const
       ENGINE_CST_OFFSET = 1000;
       ENGINE_STOP      = ENGINE_CST_OFFSET + 1;
       ENGINE_PLAY      = ENGINE_CST_OFFSET + 2;
       ENGINE_PAUSE     = ENGINE_CST_OFFSET + 3;
       ENGINE_SONG_END  = ENGINE_CST_OFFSET + 4;
       ENGINE_ON_LINE   = ENGINE_CST_OFFSET + 5;

 const
  OutputTypes: array [0..2] of TFSoundOutputTypes =
  (FSOUND_OUTPUT_WINMM, FSOUND_OUTPUT_DSOUND, FSOUND_OUTPUT_A3D);

  OutputRates: array [0..4] of Integer =
  (48000, 44100, 22050, 11025, 8000);


  Stream_LoopMode: array [0..2] of integer =(FSOUND_LOOP_OFF,
                                              FSOUND_LOOP_NORMAL,
                                              FSOUND_LOOP_BIDI);


  CD_PlayMode: array [0..3] of integer =(FSOUND_CD_PLAYCONTINUOUS,
                                          FSOUND_CD_PLAYONCE,
                                          FSOUND_CD_PLAYLOOPED,
                                          FSOUND_CD_PLAYRANDOM);

implementation

end.
