[Qt-interest] Signal Generator Software Audio Enable

If you are using 4.6 then take a look at the audiooutput example.
It creates a sine wave to test audio output.

I can't imagine a situation where you couldn't make a Qt-based sound signal generator.

You would setup your samples, and then use platform-specific calls to the audio framework of your machine.

I seem to remember reading something about QSound being rubbish, so you might have to use ALSA/OSS/DirectSound (or whatever) to actually transfer the audio samples to the sound driver and to the device.
