Filtered noise sweep tutorial.
In this tutorial we are going to make a ‘sweep’ or that wooshing sweeping noise you sometimes hear for a transition or FX in a track. We will use the FLStudio plugin 3xOsc for the noise generator (oscillators set to generate white noise only.) Also we will automate the frequency of a bandpass filter inside 3xOsc.
Here is an audio example rendered straight from the included project file to an .mp3
Okay, here we go… First, open a new project in FL Studio and add a 3xOsc.
This step is not actually necessary for this simple tutorial but it’s advised to do so so that you can add further control FX to the sound later. (eg, a delay plugin is a good one to use on this sound, in FLStudio try adding FL Delay2.) And now you can use the mixer fader to individually adjust the level of your sweep in your mix.
Add a note to be played on the step sequencer. (Or skip this and just draw one into the PianoRoll, similar to the next step which, extending our note length)
Set your note length. The example one is eight bars long.Now we will choose the filter settings. On your 3xOsc click the INS tab. In the filter section, choose BP (BandPass) and adjust the knob positions like in the picture. The MODX knob sets the frequency of the filter, and MODY sets the width of the filter. (Q)
And we can also see the automation clip has been added to the playlist:Currently it’s only bar long as we don’t have any patterns on the playlist. First, add pattern one to the playlist. Now that you can see it and it’s length, grab the right hand point on the automation clip, dragging it to the right until it’s length matches the length of our sustained note we drew earlier.

You can use this concept in most any other DAW with automation of course. The basic idea is the same no matter what you use: Automate a filter’s settings to move over time to create a ‘moving’ sound. Try experimenting with different types of filters, (LP BP etc.) and also you can obviously sweep up, down, or any more complex automations you like the sound of.
