Hi and welcome to devnet,

The progress bar could only indicate the volume, it's not really suited for spectrum analyzes. What values would you like to show with progress bars ?

megido

I dnt know, but not volumes

megido

"Install radio":http://www.screamer-radio.com/download/
and open any station
its not volume

The thing to the left ? It's a peak meter, so it shows the instant level of an audio signal (loudness). More or less it's the volume

megido

ok, how to get this loudness from phonon.AudioOutput?

megido

thank, i found it in QTmultimedia documentation

PeakValue The peak volume of the media's audio stream.

You're welcome
