How/why does Dolphin generate sound frequencies above 17 KHz?

If not, hope that a developer will do that so that we can have more info on why Dolphin generates these frequencies. My guess: resampling done in the AudioCommon mixer introduces these problems (and we already know it's very broken).

Here you go. There's the Dolphin resampled audio, the audio before resampling, and the audio before resampling resampled by Audacity.
