Now as you bring the Cutoff freq up you will hear the bass tones drop out and only the high end stuff such as cymbals will be coming through. Turn the low pass all the way down and bring the high pass all the way up. The High Pass does the same thing, but it only allows sounds higher or above the cutoff freq to pass through. Just start either full off or full on and slowly twist the cutoff knob from one extreme to the other. Also you can use this as a cool frequency based fade in or out effect on your music tracks. This is great for pulling bass-lines out of a song or sample. As you can see when you turn on a low pass filter everything under the cutoff frequency comes through while blocking everything above that cutoff. And you should now start hearing the audio come through mainly the low end things like kick drums, bass, ect. Now slowly start to bring up the Cutoff Freq knob. Start by turning all of them all the way down to the left, now if you press play in Fruity Loops you will probably hear nothing, as the filter is filtering out everything and not allowing any audio to pass through.įirst turn up the Low Pass knob all the way, this basically turns it on. Our main focus here will be on the Cutoff Freq, Low Pass, and High Pass knobs. In Fruity Filter you will see 6 controls (Cutoff freq, Resonance, Low Pass, Band Pass, High Pass, and x2). Over in the right hand side in an effects slot, click the little down arrow choose "Select" and stick in a Fruity Filter. Now pull up the Mixer (either by selecting it in "View" at the top nav-bar, or pressing F9) and select the Master channel in the Mixer. Try to use something that has a full range of sounds, including kick drums, bass guitar or synth, snare, cymbals, hi-hats, maybe some guitar or samples. So, start Fruity Loops and either lay down a basic beat or load up a project or one of the demo songs.
The best way to learn this is just to open up FL Studio and tweak around with the settings on the filter. In this lesson we will be working with the Fruity Filter. A low pass filter allows all the audio below the cutoff frequency through or to "pass", things such as kick drums, bass guitar, and other low end instruments likewise, a high-pass filter will let all the high frequency audio through for example, cymbals, high ringing synths, ect.
The two we'll learn about in this tutorial are the "low-pass" & "high-pass" filters. Basically an audio filter is just as the name says it filters out audio either above or below a certain frequency-called the cutoff frequency.
