Bad pitch shifter:
	This is a weird middle-tone-only pitch shifter, that also seems to add a reverb-like
	effect to the sound.
	A pitch shifter changes the pitch of a sound without altering the duration - unlike
	changing the speed of a tape recorder or a record player.

Spectral distortion:
	This special effect limits every single frequency band to the maximum threshold you
	specify using the "spectral distortion" slider. Basically this brings forth all the
	disharmonic parts of the sound.

Spectral cleaner:
	This is more or less the opposite of "Spectral distortion", even though it will not
	completely reverse the effect of it. It isolates the prominent frequencies, thus leaving
	only the harmonic parts of the audio.

This filter is extremely eksperimental, but has already proven to be useful for certain
purposes. Eg. I've been able to isolate the sounds of birds singing from running water, even
though they're located in the same frequency areas!

To see what the sliders do to the different frequencies, it may help to see a frequency analysis
of the original sound, and the results of using the parameters by them selves:
