Week 147: The Gourmet Flanger I’m always looking for ways to get the “tape flanger” sound of "through-zero flanging" without tape. The differentiating aspect of through-zero flanging is that when the delayed and straight signals are out of phase and at the same delay time, they cancel to create a split-second of silence. Although the Sonitus Modulator offers a Tape option that approximates this sound, you don’t have control over how the Tape option works—with real flanging, tape motion was always somewhat variable; more often than not, the tape would sort of stagger around the through-zero point. So can we get an even more realistic tape flanging sound with SONAR?
Of course we can! The setup is a little complex, because we need to take the audio we want to flange and send it to two buses, or the same Patch Point in two Aux Tracks (as in the screen shot below). Note that with Aux Tracks, Input Echo needs to be enabled. Each Aux Track has a Sonitus Modulator effect, with one set for a constant 0.1 ms delay (labelled as the “Reference” track, which is also set out of phase), while the other “Flanger” track is set to sweep so it goes up to a lesser amount of delay than the zero-crossing point (in this case, 0.01 ms). Therefore, the signal cancels once when it sweeps up through the 0.1 ms delay point, and again when it sweeps back down through the 0.1 ms delay point. You want the interval between these two times to be fairly short; however you can lengthen this by increasing the Reference track’s delay parameter.
The Mix controls should be set to 100% delayed signal for the maximum effect. The Flanger track’s Depth control determines how low the flanger goes. 3-5 ms seems about right, but feel free to increase this for a wider-range effect that gets more into the chorus/delay range. Also, try different LFO waveforms. My favorites are the Triangle and Peak / Dip waveforms.
But wait…there’s more! Turning off the Phase button on the Reference track produces a different timbre that’s also useful, but the signals don’t cancel at the through-zero point, so they create a volume increase. In that case you might want to lengthen the Flanger track’s Delay parameter to avoid the through-zero point. I prefer the out-of-phase sound because it sounds more like “classic” flanging to me, but at least you have options. You can also experiment with increasing the amount of feedback; just remember to keep the levels identical.
And that’s it for gourmet flanging, so...
bon appétit!
