[win 32] loading dll (lame encoder)

Great! I seem to have sorted it out like this:

Code:

---

int k = 0;
 while(1)
 {
  if(stop_thread_flag)
  break;
  // CALLBACK EVENT
  WaitForSingleObject(hevent, INFINITE);

  if(buff[k].dwFlags & WHDR_DONE && !stop_thread_flag)
  {
  // Save WAVE
  hFile2.write(buff[k].lpData, buff[k].dwBytesRecorded);
  dwWAVBufferCounter  += buff[k].dwBytesRecorded;

  // Encode samples
  //
  // (LPSTR) buff[k].lpData is (system_buf_len) bytes long (8 BIT)
  // (PSHORT)buff[k].lpData is (system_buf_len)/2 (16 BIT)
  //
  result = beEncodeChunk(hbeStream, dwSamples, (PSHORT)buff[k].lpData,
pMP3Buffer, &dwWrite);

  // Save MP3
  hFile.write((LPSTR)pMP3Buffer, dwWrite);
  dwMP3BufferCounter  += dwWrite;

  waveInAddBuffer(hwi, &buff[k], sizeof(WAVEHDR));
  }

  if(k == num_buffers -1)
  k = 0;
  else
  k++;
 }

---

basically I get the audio thru the WAVFORM API to a 2304*2 bytes long buffer
(LPSTR),

so that when I do (PSHORT)buffer to the DLL it'll look like 2304 samples (16
BIT)

having said that, I am getting mono audio...

the whole code is avaible here:

http://theartofweb.net/cpp/mp3Recorder_05.txt

the programm is supposed to grab the audi from a device and save it realtime
in both WAVE and MP3 files

I use lame_enc.DLL to convert wave file to mp3 file, it works OK for all 16-bits-per-sample wave files, but if the wave files are 8-bits-per-sample wave files, the results mp3 files are only noise. Who could tell me where is wrong? Thank you!

Maybe lame_enc doesn't support 8-bits-per-sample wave files. Have you checked the documentation?

I unzip lame-3.99.5.tar, in the folder lame-3.99.5\doc\html, there are some help files. I read these files, but don't find whether lame_enc.dll supports 8-bits-per-sample wave file.
