Function  :	Lets you edit your sample with a 64 ! Band-Equalizer.
Parameters:	Sliderfield	With the sliders you can edit the amplification
				for every single band. Possible values are 0-
				400%.
		Bands		Just how many bands should SFX use. Less Bands
				means less math, but you lose out on accuracy.
		Steps		SFX does a transformation every <steps> sample-
				values. Lower values mean better quallity but
				longer calculation. Steps should be the half of
				bands.
		Window		Windowfunction
		Range		Simple tool to do a straight line between two
				bands. For those can't draw these lines
				(like me-English Ed) just click on the
				first band then range and then the second band.
		Mode		Gives you the choice of moving just one
				slider or ALL.
		Band		number of the current band you're working at
		Val		value of current band
		BandS,E		show the frequency range for the current band.
		Arrow-Gadgets	for moving the "curve"
		F-Gadget	Flip , mirrors the "curve" round the Y-axis
ARexx     :	Bands	0->4/1->8/2->16/3->32/4->64
		Steps	0->1/1->2/2->4/3->8/4->16/5->32
		@{"W1" link /guides/sfx-arexx.guide/AREXX_wfkt}	Windowfunction
		Eqf	<Number> <Value>
Notes     :	The Equalizer does its math with the @{" Fourier-Transformation " link /guides/sfx-glossary.guide/FourierTransformation}.
		This returns frequency amounts for every sample value, which
		are then multiplied with the factors (stuff you played with)
		and then reassembled with resynthesis. For more bands you a
		more accurate manipulation.
		Be advised (index finger in ye face) that calculations are
		very complex and can therefore take their time.
		(My advice is : Sample the sound again until you get what
		 you want. Or listen to it from the CD or whatever
		 and fiddle with the Amp or Equalizer controls(real one:)
		 THEN come here and apply that to your sample. EnglishEd)
