如何在 Delphi 中播放 wav 文件？

Question

Delphi 中有哪些函数可以播放声音文件？

Answer 1

这是最快的方法：

uses MMSystem;

procedure TForm1.Button1Click(Sender: TObject);
begin
  sndPlaySound('C:\Windows\Media\Tada.wav',
    SND_NODEFAULT Or SND_ASYNC Or SND_LOOP);
end;

procedure TForm1.Button2Click(Sender: TObject);
begin
  sndPlaySound(nil, 0); // Stops the sound
end;

Answer 2

使用来自 WIN32-API（单元 MMSystem）的函数 sndPlaySound：

sndPlaySound('C:\Windows\Media\Tada.wav', SND_ASYNC);

Answer 3

简单：

procedure PlaySoundFile(FileName: string);
begin
 if FileExists(FileName)
 then PlaySound(pchar(FileName), 0, SND_ASYNC or SND_FILENAME);  

 { Flags are:
    SND_SYNC  =0 = Start playing, and wait for the sound to finish
    SND_ASYNC =1 = Start playing, and don't wait to return
    SND_LOOP  =8 = Keep looping the sound until another sound is played  }
end;

人们也引用了 sndPlaySound，但这只是为了向后兼容。 所以，不要使用它！

procedure PlayWinSound(SystemSoundName: string);
begin
 Winapi.MMSystem.PlaySound(PChar(SystemSoundName), 0, SND_ASYNC);
end;
