Get loudness level from a wav-file at a given time

[random_qt]

hi!
Is there a way I can receive with Qt/Phonon the loudness level of a wav-file at a specific time?

I am looking for a way to retrieve the point of time the loudness exceeds a certain level.

Thank you for your help!

As far as I know Wave files contain aplitude and frequency of sound. The larger the amplitude, the louder the sound. Bottom line is you have to analyze the file itself to be able to determine the volume of a particular sample and Phonon doesn't do such things, the backend does.
