QMediaRecorder, how to output data into the RAM first

[xhsoldier]

QMediaRecorder::setOutputLocation(QUrl::fromLocalFile("E:\\background.wav"));

it can output the sound into the file.
while I want to process the data before it is saved into the file. I need to deal the output data in RAM.
how to do this?

Hi,

I suggest you take a look at the spectrum analyzer demo application - more details in this Qt Labs article.
