Detailed Description

This is a struct containing all the parameters needed to describe a vocal morpher effect.

The vocal morpher consists of a pair of 4-band formant filters, used to impose vocal tract effects upon the input signal.

Member Enumeration Documentation

enum Mezzanine::Audio::VocalMorpherParameters::MorpherWaveform

The shape of the wave if it were viewed on an oscillator.

Enumerator
EMW_Sinusoid	A curved oscillation with smoother transitions at peak frequencies.
EMW_Triangle	A linear oscillation with rapid transitions at peak frequencies.
EMW_Saw	A curved upward oscillation with a rapid drop at it's peak frequency.

Member Data Documentation

MorpherPhoneme Mezzanine::Audio::VocalMorpherParameters::PhonemeA

The source phoneme.

Remarks

If both parameters are set to the same phoneme, that determines the filtering effect that will be heard. If these two parameters are set to different phonemes, the filtering effect will morph between the two settings at a rate specified by Rate.

Definition at line 633 of file effectparameters.h.

Integer Mezzanine::Audio::VocalMorpherParameters::PhonemeACoarseTune

This is used to adjust the pitch of phoneme filter A in 1-semitone increments.

Remarks

Range: -24 to 24

Definition at line 640 of file effectparameters.h.

MorpherPhoneme Mezzanine::Audio::VocalMorpherParameters::PhonemeB

The destination phoneme.

Remarks

If both parameters are set to the same phoneme, that determines the filtering effect that will be heard. If these two parameters are set to different phonemes, the filtering effect will morph between the two settings at a rate specified by Rate.

Definition at line 637 of file effectparameters.h.

Integer Mezzanine::Audio::VocalMorpherParameters::PhonemeBCoarseTune

This is used to adjust the pitch of phoneme filter B in 1-semitone increments.

Remarks

Range: -24 to 24

Definition at line 643 of file effectparameters.h.

Real Mezzanine::Audio::VocalMorpherParameters::Rate

This controls the frequency of the low-frequency oscillator used to morph between the two phoneme filters.

Remarks

Range: 0.0 to 10.0

Definition at line 648 of file effectparameters.h.
