    Hi I have a question is it possible to record audio from the microphone and save it in database, for later playback.

    in case if you can as I can do it or I have to use.

    I was thinking about using ffmpeg

      Yes you can. Have a look at "QAudioInput":http://qt-project.org/doc/qt-4.8/qaudioinput.html to get started, and feel free to ask more questions if you need help :)

      Basically, you need:

      QAudioInput, to convert sound into bytes

      A 3rd-party library (like FFmpeg) to convert bytes into an audio file

      A database driver (like "Qt's SQL drivers":http://qt-project.org/doc/qt-4.8/sql-driver.html ) if you want your program to store it in a database. You don't need this, if you store the audio files directly on your hard disk -- just use "QFile":http://qt-project.org/doc/qt-4.8/qfile.html

          Hello topo1, there is already an example for using QAudioInput in the link I provided. Please try it first, and let us know what you learnt.

          Also, could you tell us:

          What experience do you have with Qt?

          What experience do you have with QIODevice?

          What experience do you have with using 3rd-party libraries in your program?

          After that, I'll be happy to provide some more examples.

          [quote author="topo1" date="1348517254"]JKSH hello, well I'm using mysql[/quote]Then you need to build the MySQL plugin for Qt. You can find out how in the "official guide":http://qt-project.org/doc/qt-4.8/sql-driver.html#how-to-build-the-qmysql-plugin-on-windows , or search for "MySQL" in this forum (e.g. http://qt-project.org/forums/viewthread/18828/ )
