Detailed Description

This is a struct containing all the parameters needed to describe an flanger effect.

The flanger effect creates a "tearing" or "whooshing" sound (like a jet flying overhead).

Member Enumeration Documentation

enum Mezzanine::Audio::FlangerParameters::FlangerWaveform

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

Enumerator
EFW_Sinusoid	A curved oscillation with smoother transitions at peak frequencies.
EFW_Triangle	A linear oscillation with rapid transitions at peak frequencies.

Member Data Documentation

Real Mezzanine::Audio::FlangerParameters::Delay

The average amount of time the sample is delayed before it is played back; with feedback, the amount of time between iterations of the sample.

Remarks

Range: 0.0 to 0.004

Definition at line 521 of file effectparameters.h.

Real Mezzanine::Audio::FlangerParameters::Depth

The ratio by which the delay time is modulated by the LFO.

Remarks

Use this parameter to increase the pitch modulation.

Range: 0.0 to 1.0

Definition at line 514 of file effectparameters.h.

Real Mezzanine::Audio::FlangerParameters::Feedback

This is the amount of the output signal level fed back into the effect's input.

Remarks

A negative value will reverse the phase of the feedback signal. Use this parameter to create an "intense metallic" effect. At full magnitude, the identical sample will repeat endlessly. At less than full magnitude, the sample will repeat and fade out over time.

Range: -1.0 to 1.0

Definition at line 518 of file effectparameters.h.

Integer Mezzanine::Audio::FlangerParameters::Phase

This changes the phase difference between the left and right LFO's.

Remarks

At zero degrees the two LFOs are synchronized.

Range: -180 to 180

Definition at line 508 of file effectparameters.h.

Real Mezzanine::Audio::FlangerParameters::Rate

The number of times per second the LFO controlling the amount of delay repeats.

Remarks

Higher values increase the pitch modulation.

Range: 0.0 to 10.0

Definition at line 511 of file effectparameters.h.
