Tips, tricks and troubleshooting

Factory presets

The Formant block is showcased in a few Factory presets, such as MEN IN THE BOX.

Talkbox

The Formant effect lets you create a talkbox effect and, if you really really must, play Livin' on a Prayer.

Attach a controller to the Control parameter in the Formant block, either an internal controller such as an LFO, or an External controller like a pedal.

A real talkbox doesn't use a speaker, so experiment with leaving out a Cab block in the preset.

For more information see:

• The forum discussion Living on a Prayer Without an Expression Pedal
• Search the forum for banshee or talkbox.
• Wikipedia's Talk box article.

Emphasize frequencies

The Formant can be used to emphasize frequencies, for example when creating a Seek Wah effect. Put the Formant after the Wah block.

Voice Reverbs

FRACTAL AUDIO QUOTES

---

[1] Put the Formant Filter block in series with the Reverb block and run the two in parallel with the Reverb Mix at 100%.

LFO

Make the Formant do its thing without an expression peak by attaching the LFO controller to the Control parameter.

Make other sounds more vocal

Add the Formant to make other sounds more like human vocals. Try it with the vowels A + E + I.

Prevent clipping

Because of the resonant frequencies of the Formant filter, it's easy to make the digital signal clip. Keep sufficient headroom to avoid clipping.
