[Solved] Get the audio data sent to the soundcard / get the audio data from another application



  • Hello,

    I am programming an audio analyzer. That why, I want to retrieve all datas played from another application (for instance: windows media player, microphones (this one I know how to do it) ) in order to process the datas, then sent it to the soundcard. I tried few things with QAudioInput, QAudioOutput or QIODevice without success. I am also using FFmpeg in my program, in case it might help.

    Do you have any idea how to get the audio data of another software?

    Thank you,
    Matt141



  • I found what I was looking for.

    I had to use QInputDevice. But before I had to loopback my soundcard so the ouput of the soundcard can be read as an input device by an object QInputDevice. This has to be done by configure the "recording devices" in windows.

    Bye,
    Matt141
