most people would say to use a high-shelf to boost highs. I believe when you use more than 1 dot on other filter types, such as a 'peaking filter' (the one that looks like a cross in the icons, also the standard type) it acts as ' the number of instances of the filter' so 4 dots on a peaking filter would be like 4 instances of that filter layered on top of each other i believe.Īnd if your wondering about which filter type to use. 'the more the dots, the steeper the curve to cut the frequencies and thus the more decibels of cut you will most likely see'. If i recall correctly its 12dB per octave at 1 dot and 48dB per octave at 4 dots. You will also notice that at the top right, above each slider, there is also a 'Filter Type Chooser'(each filter type is represented by a small icon of a unique shape which you can hover your mouse over, click and drag up or down to change and if you look at the top left of FL Studio while doing this it'll tell you the name of each filter type) and lastly there is a 'Filter Slope' section which is represented by dots underneath the filter type icon (these are circled in this image) you can also click and drag up or down on these to change the depth of the slope. You can easily tell which one is which by the unique color of each band/token.

The Bandwidth control labeled 'BW' is the one you want to adjust to modify the width of the curve of any band, just drag it up or down, like everything else. If you look to the right side of the plugin you'll notice Each band or 'token' has its own slider, a frequency adjuster(labeled FREQ) at the bottom, a Bandwidth Adjuster(labeled BW) also at the bottom. So you'll notice that you can do it all with the mouse by dragging those tokens except that you cannot control the width of the curve, only the location in the spectrum (the frequency) and the amount of boost or cut (the decibels). In this image above, the peaks didnt go up into -10dB so thats why you cant see any orange. How this works, basically, is the brightest red that you will see (which is more towards an orange) represents frequencies that are around -10dB and above in loudness, and black represents frequencies that are around -60dB and below in loudness and everything in between you can just approximate yourself. If you have audio coming through on the mixer track you'll notice that the window will light up with shades of red. On the main spectrum window on the left you see 7 what are called 'tokens', these are Equalizer Bands which you can freely click and drag about to alter the frequencies of the audio on the mixer track in which that Plugin resides.
