White noise sweep is something you’ve probably heard on every trance, house, techno and various other EDM style songs. It’s one of the basic effects used in build ups.
In this tutorial I will show you how to make a uplifting white noise sweep in FL Studio. It’s very simple.
1. Load a 3xOsc and choose ‘noise’ (that’s white noise btw) as a oscillator shape for each three oscillators. Also, assign the 3xOsc to a free mixer track.
2. Add a pattern to the Playlist, open the Piano Roll -view of the 3xOsc and draw a 8 bar long (or however long you want your sweep to be) note (C3 for example).
3. Open the Mixer and drop a Fruity Free Filter to the 3xOsc mixer track. Leave all the other parameters as is, but set Cutoff Frequency to around 125-130Hz (this is the starting frequency of the sweep).
4. Right click on the Freq -knob and choose ‘Create automation clip’.
5. In the Playlist, raise the second envelope point to 90-100% (that’s between 10-16kHz) or whatever you want the end frequency of your sweep to be.
Now, listen the end results:[audio:http://howtomakeelectronicmusic.com/wp-content/uploads/audio/White-Noise-Sweep.mp3]
I think this is officially called a ‘uplifter’.
If you want a more ‘whistling’ sounding sweep, raise the Q (resonance) level in the Fruity Free Filter:
So in a nutshell, we are using low pass filter and automation to sweep the filter cutoff frequency from 120-130Hz up to 10-12kHz or more. You could’ve done this also by using Fruity Parametric EQ 2 and the effect would’ve been pretty much the same, though it’s faster to set it up using Fruity Free Filter.
Experiment by drawing different types of filter cutoff Frequency automation envelopes. For example, if you reverse the envelope, you’ll get a ‘downlifter’.
That’s it. 🙂
