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

Mine is NTSC, from 2008, and Dolphin shows it as RVL-WiiSystemmenu-v449, although that doesn't correlate obviously to any versions listed on the Wiki. Oh well, if a version from one of your games works for you, great, if not, you can still see spikes in the spectogram when recording during gameplay as well so it shouldn't be a problem. Zoom in on the spikes and then switch to waveform view and you should be able to find a glitch in that area.
