Handle windows audio volume

**Raccoon29** · 24th November 2009, 14:34

Hello everyone,

I'm trying to manipulate windows system audio from a qt application (such as: raise/lower pitch, enable/disable audio, and so on...), just like if I act on the system audio gui panel of windows.
I guess I should use winApi, but since I never had to struggle with this stuff, I'd much appreciate some tips from someone that already practiced it in the past.
Every sort of tip is welcome

The question is: how to handle Windows system audio from Qt application?

EDIT: you can have a look at Phonon.

That's a great library! But sadly it seems that isn't able to edit system audio...

Thank you so far anyway. Any other idea?

you asked about handling audio, its not the same as editing audio.
Qt is not meant for that.
For editing media you need specialized libs.
Google for it.

Sorry, I mistyped: I don't intend to edit/modify media files, I just would need to (at least) disable system audio, like that checkbox in Windows audio control panel "disable".
Just this. No file editing.

By the way, I used "General programming" forum because I see this could be not a Qt subject, but I think too this place is full of experienced people that could give some important tip... Google is not still been usefull so far about this
