Audio / Recording stereo sound

« on: August 07, 2012, 12:12:23 pm »

I have a problem with the recording of stereo sound. 
 
It is  code:

#include <SFML/Audio.hpp>
#include <iomanip>
#include <iostream>
int main( ){    
    if (sf::SoundRecorder::CanCapture() == false)
    {
        std::cout << "Sorry, audio capture is not supported by your system" << std::endl;
        return EXIT_SUCCESS;
    }  
    unsigned int SampleRate=48000;
    std::cout << "Press enter to start recording audio";
    std::cin.ignore(10000, '\n');
    sf::SoundBufferRecorder Recorder;    
    Recorder.Start(SampleRate);
    std::cout << "Recording... press enter to stop";
    std::cin.ignore(10000, '\n');
    Recorder.Stop();

    // Get the buffer containing the captured data
    const sf::SoundBuffer& Buffer = Recorder.GetBuffer();

   const short  int*hbuf;
   hbuf=Buffer.GetSamples () ;
 
   //Display 10 samples of captured sound
 
   int i;
   for (i=0; i<10;i++) std::cout << *(hbuf+i)<<"\n";

    // Display captured sound informations
    std::cout << "Sound information :" << std::endl;
    std::cout << " " << Buffer.GetDuration()      << " seconds"           << std::endl;
    std::cout << " " << Buffer.GetSampleRate()    << " samples / seconds" << std::endl;
    std::cout << " " << Buffer.GetChannelsCount() << " channels"          << std::endl;

    return EXIT_SUCCESS;
}

It works for:
CaptureDevice = alcCaptureOpenDevice (NULL, SampleRate, AL_FORMAT_MONO16, SampleRate)
 in SoundBufferRecorder

I have modified:
CaptureDevice = alcCaptureOpenDevice (NULL, SampleRate, AL_FORMAT_STEREO16, SampleRate)  in SoundBufferRecorder  and compiled SFML-audio,    but it does not work.
I think, I should do something else for stereo recording. I would be grateful for your help.
