QMediaPlayer - fequency

[Toxiik]

Hello i try to implement a media player using Qt5 and QMediaPlayer.
I would like to know the frequency of the media which is played.

Because for instance when the frequency is high I would like to put a picture representing a hight frequency ect..

Is that possible?
Thanks

ps: sorry for my english i'm french

The signal processing you'll have to do it yourself and for the GUI you can use e.g. Qwt.
