I implemented an audio player using Qt Widgets and Phonon for Symbian Anna / Belle phones. My Qt and C++ skills are very basic so far, but at least the app works now and can play music.
It would be nice to have an equalizer or something to adjust the sound (bass, middle, treble as minimum) as next step.
There seems to be no easy solution directly in Phonon; but i found header files like this one which could be helpful if one knows how to use it: audioequalizerutility.h
Does anybody has an idea how i can implement an equalizer or point me to the right direction?
