6 band equalizer with Qt and C++



  • Hello there, my first time here and to Qt too :)

    So, I have this rough idea of writing an equalizer app for Windows 7 using Qt and C++. The app should not have any GUI for managing it, all management would be done via CLI (I want to make it as a service). The problem is that I don't know how to get started!!
    I read some information about VST and some audio transformation procedures, which kind of helped, but in no tutorial or project they explained how to actually interact with the OS so you can use the equalizer on some audio. Calculations for audio transformations are the thing worrying me the least right now.
    What I want to do is to use this equalizer to manage all the output of the sound card. For some sound cards using the Realtek AC'97 chip they integrated a 10 band audio equalizer directly with Windows (have a look: http://img.networkdigitale.com/di/K2ZA/buil-inequalizer.png ), so all audio processing is applied to all audio getting out of the sound card, to all channels. That's my same goal, but I have found nothing on the web about this.
    Could someone point me the right way? Some example code would also be great, if possible :)

    Thanks to anyone who is going to answer me!
