I have been a Qt developer for 5 years and C++ for developer for 12 years but never really did any audio programming. For a big project I am working on 2 multitouch applications. One of which needs basic audio support, looping an audio file, being able to stop it at any time with a fadeout. I was hoping to use Phonon for this but it doesn't seem to work with Mingw. Since I want to use the same Qt SDK for both apps and I already finished the other app using Mingw, I am a bit puzzled how to get the audio working without setting up a separate Visual C++ environment for the second app.
I looked at Qt multimedia classes, this could be an option, but I found no support for fade out. Any suggestions? I have limited time on this but the audio support I need is so simple, yet trivial part of the app experience.
