    I dont think there is audio capturing facility in Qt ... You may however check phonon.

    Also there was going to be audio related stuff in 4.6 . You can check the latest 4.6-technology-preview.

    Exactly the same as you would do it without Qt.

    what do you mean by:
    how to call FFMPEG from QT?
    I don't know exactly what FFMPEG is (just looked for a while on it's webpage), but if you want to run some other application from your's - use QProcess. But my guess is that FFMPEG is a library, so you have to use it like any other library in C++ - Qt has nothing to do with it, as it is also C++ library.
    I would like to be a "Guru"

    Useful hints (try them before asking):
    1. Use Qt Assistant
    2. Search the forum

    If you haven't found solution yet then create new topic with smart question.

    Just like any other C function from any other C++ application.

    Just a side note, as far as I know ffmpeg will not let you record audio. It's a set of libraries related to coding/decoding audio and video. You need the actual audio data to be there already.

    If you keep asking the same question again and again, you will not be getting different answers. Actualluy you will probably stop getting answers at all. Please search the forum and STFW for audio recording.
