2. Methods

• Object creation

  function CreateSoundObject: ISound;
  

• A Sound object requires a file name to the stored sound file. This is stored as IFilename in the object:

  function Filename: IFilename;
  

• Total length of the sounds in milliseconds

  function GetSoundDuration: Integer;
  procedure SetSoundDuration(const Value: Integer);
  

• Adjust the playing time of the sound containing object to the length of the sound

  function GetUseSoundLength: Boolean;
  procedure SetUseSoundLength(const Value: Boolean);
  

• Fade-out background music when playing the sound

  function GetFadeOutBackgroundMusic: Boolean;
  procedure SetFadeOutBackgroundMusic(const Value: Boolean);
  

• Fade-in duration of the sounds in milliseconds

  function GetFadeOutDuration: Integer;
  procedure SetFadeOutDuration(const Value: Integer);
  

• Volume in percent

  function GetMasterVolume: Integer;
  procedure SetMasterVolume(const Value: Integer);
  

• Start time of the sounds in milliseconds

  function GetStartPos: Integer;
  procedure SetStartPos(const Value: Integer);
  

• End of the sound object in milliseconds

  function GetSoundEnd: Integer; 
  procedure SetSoundEnd(const Value: Integer);
