Thanx for reply
I found a function in this site, and I paste in my code but an error servenu: QAudioInput :: No such file or directory?
I searched this problem but I have not solved.
the code is :

QFile outputFile;         // class member.
QAudioInput *audioInput;  // class member.
...
void startRecording()
{
    outputFile.setFileName("/tmp/test.raw");
    outputFile.open( QIODevice::WriteOnly | QIODevice::Truncate );
    QAudioFormat format;
    // set up the format you want, eg.
    format.setFrequency(8000);
    format.setChannels(1);
    format.setSampleSize(8);
    format.setCodec("audio/pcm");
    format.setByteOrder(QAudioFormat::LittleEndian);
    format.setSampleType(QAudioFormat::UnSignedInt);
    QAudioDeviceInfo info = QAudioDeviceInfo::defaultInputDevice();
    if (!info.isFormatSupported(format)) {
        qWarning()<<"default format not supported try to use nearest";
        format = info.nearestFormat(format);
    }
    audioInput = new QAudioInput(format, this);
    QTimer::singleShot(3000, this, SLOT(stopRecording()));
    audioInput->start(&outputFile);
    // Records audio for 3000ms
}

Because you are missing QT += multimedia in your .pro file.

On a side note, asking on a community forum for someone to do the work for you because it's urgent for you isn't exactly professional. If you are in such a hurry then consider hiring someone with the expertise you need.
