formant()

Category

Filter

Description

Formant filter. It shapes an input signal toward vowel-like colors; the vowel argument is usually 0.0 to 1.0 and amount controls how strong the formant is.

Arguments

• input: audio/control signal to process
• vowel: vowel position, typically 0.0 to 1.0
• amount: effect amount or strength

Typical Values

Vowel is typically 0.0 to 1.0. Amount is usually 0.0 to 1.0; higher values exaggerate the vocal color.

Example

formant(sin(X)+0.18*saw(0.5*X), 0.22+0.28*param(2), 0.18+0.32*param(4))

Notes

For pitched oscillator functions, X already contains the current MIDI note pitch and transpose information. Prefer saw(X), sin(X), or pwm(X, 0.4) unless you intentionally want an octave or ratio shift such as 0.5*X or 2*X.
