@kayakaan02 https://doc.qt.io/qt-5/qaudiooutput.html#start-1 returns QIODevice* which you can use to read the data (see https://doc.qt.io/qt-5/qiodevice.html#readyRead and https://doc.qt.io/qt-5/qiodevice.html#readAll

@jsulm Thank you! I didnt see this. So as I read the data real-time it can also append data to the file?
@kayakaan02 Yes, you can also write the data you get from the QIODevice into a file.

@jsulm I've got an another question, this can read the data but how can I access it? where does it store what it just read? seems like It doesn't return anything.

What do you mean? When you call QByteArray QIODevice::readAll() it returns a
QByteArrayof the bytes read. If you have your owncharbuffer you would prefer it read into there is also qint64 QIODevice::read(char *data, qint64 maxSize). -

As I said, It's the same code as shown as example at QT Doc(here)

That is not possible provided you call
readAll()in the slot forreadyRead(), just as I see you have marked as the correct answer from @jsulm above..... If you callreadAll()anywhere else it could be empty. Your code cannot be the same as the example you quote since that does not usereadAll(). -
