hola aqui encontre algo por internet, que me funciona teniendo los archivos bass.dll,bp.dll,el audio y el archivo .iss pero al copiarlo al programa no funciona

Source: "lugar donde esta el archivo de musica"; Flags: dontcopy nocompression
Source: "C:\Program Files (x86)\Inno Setup 5\Dll Pack\bp.dll"; Flags: dontcopy

var
mp3HNDL:DWORD;

function BASS_Init(device: Integer; freq, flags, win: DWORD;clsid:integer): Boolean; external 'BASS_Init@{tmp}\BASS.dll stdcall delayload';
function BASS_Free: Boolean; external 'BASS_Free@{tmp}\BASS.dll stdcall delayload';
function BASS_Start: Boolean; external 'BASS_Start@{tmp}\BASS.dll stdcall delayload';
function BASS_Stop: Boolean; external 'BASS_Stop@{tmp}\BASS.dll stdcall delayload';
function BASS_Pause: Boolean; external 'BASS_Pause@{tmp}\BASS.dll stdcall delayload';
function BASS_ChannelPlay(handle: DWORD; restart: BOOL): Boolean; external 'BASS_ChannelPlay@{tmp}\BASS.dll stdcall delayload';
function BASS_ChannelPause(handle:DWORD):Boolean; external 'BASS_ChannelPause@{tmp}\BASS.dll stdcall delayload';
function BASS_ChannelStop(handle:DWORD):Boolean; external 'BASS_ChannelStop@{tmp}\BASS.dll stdcall delayload';

function BASS_StreamCreateFileLib(mem: BOOL; fil: PAnsiChar; offset, length, flags: DWORD): DWORD; external 'BASS_StreamCreateFile@{tmp}\bp.dll stdcall delayload';

function BASS_StreamCreateFile(mem: BOOL; fil: AnsiString; offset, flags: DWORD): DWORD;
var size_:Longint; Buffer:ansistring;
begin
if mem then begin
#ifdef IS_ENHANCED
size_:=ExtractTemporaryFileSize(fil);
SetLength(Buffer,size_);
ExtractTemporaryFileToBuffer(fil,Cast{#defined UNICODE ? "Ansi" : ""}StringToInteger(Buffer));
#else
if not FIleExists(ExpandConstant('{tmp}\')+fil) then ExtractTemporaryFile(fil);
FileSize(fil,size_);
SetLength(Buffer,size_);
LoadStringFromFile(ExpandConstant('{tmp}\')+fil,Bu ffer);
#endif
Result:=BASS_StreamCreateFileLib(mem,Buffer,0,size _,flags);
end else begin
Result:=BASS_StreamCreateFileLib(mem,fil,offset,0, flags);
end;
end;

function InitializeSetup: Boolean;
begin
ExtractTemporaryFile('BASS.dll');
ExtractTemporaryFile('bp.dll');
BASS_Init(-1,44100,0,0,0);
BASS_Start;
#ifdef MEMORY
mp3HNDL:=BASS_StreamCreateFile(TRUE,'sound.mp3',0, 4); // play from memory
#else
ExtractTemporaryFile('sound.mp3');
mp3HNDL:=BASS_StreamCreateFile(FALSE,ExpandConstan t('{tmp}\sound.mp3'),0,4); // play from file
#endif
BASS_ChannelPlay(mp3HNDL,True);
Result:=true;
end;

procedure DeinitializeSetup();
begin
BASS_Stop;
BASS_Free;
end;

los otros 2 archivos bass y bp los coloque en la carpeta del inno del programa como se muestra, pero al ejecutar me tira error "duplicate identifier INITIALIZESETUP" esta es la linea : function InitializeSetup: Boolean;

ingles google:
