关于 directSound 的问题(100分)

pSDC : IDirectSoundCapture;
pDSCB : IDirectSoundCaptureBuffer;

wfex: TWaveFormatEx;
dscbd: DSCBUFFERDESC;

hr:= DirectSoundCaptureCreate(nil,pSDC,nil);
if not SUCCEEDED(hr) then

begin

ShowMessage('DirectSoundCaptureCreate error');
end;


ZeroMemory(@wfex,sizeof(TWaveFormatEx));
wfex.wFormatTag :=WAVE_FORMAT_PCM;
wfex.nChannels:=1;
wfex.nSamplesPerSec:=16000;
wfex.nAvgBytesPerSec:=32000;
wfex.nBlockAlign:=2;
wfex.wBitsPerSample:=16;
wfex.cbSize:=0;


dscbd.dwSize:=sizeof(DSCBUFFERDESC);
dscbd.dwFlags:=1;
dscbd.dwBufferBytes:=wfex.nAvgBytesPerSec;
dscbd.dwReserved:=1;
dscbd.lpwfxFormat:= @wfex;

hr:= pSDC.CreateCaptureBuffer(dscbd,pDSCB,nil);
if not SUCCEEDED(hr) then

begin

ShowMessage('error');
exit;
end;
