    Hi! I'm trying two things using qaudiorecorder:

    • Record on top of an existing file (concatenating the data of the previous and the actual record)
    • While recording, change timer (exemple: for a 1 minute record paused right now, set the timer to 50 seconds so that the 10 last seconds get erased, and so that i can keep recording after)

    If you know how to do this on qt (if it is actually possible), please leave me a link/advice!

    (sorry for my english)

      Hi and welcome to devnet,

      You can't do that with QAudioRecorder. These kind of advanced "mixing" feature are out of QtMultimedia's scope currently.

        @SGaist Thanks for your answer, kinda what i was expecting, i guess i'll have to use a third-party program for that kind of stuff :/
        Do you know if they have plans to upgrade their qtmultimedia and allow us to do this kind of stuff anytime?

          I don't know the current roadmap of QtMultimedia. But a project that you might be interested in is QtAV
