Detailed Description

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

The chorus effect essentially replays the input audio accompanied by another slightly delayed version of the signal, creating a "doubling" effect.

Member Data Documentation

Real Mezzanine::Audio::ChorusParameters::Delay

This property controls the average amount of time the sample is delayed before it is played back.

Remarks

This property can also control with feedback, the amount of time between iterations of the sample. Larger values lower the pitch. Smaller values make the chorus sound like a flanger, but with different frequency characteristics.

Range: 0.0 to 0.016

Definition at line 391 of file effectparameters.h.

Real Mezzanine::Audio::ChorusParameters::Depth

This property controls the amount by which the delay time is modulated by the Low Frequency Oscillation.

Remarks

Range: 0.0 to 1.0

Definition at line 383 of file effectparameters.h.

Real Mezzanine::Audio::ChorusParameters::Feedback

This property controls the amount of processed signal that is fed back to the input of the chorus effect.

Remarks

Negative values will reverse the phase of the feedback signal. At full magnitude the identical sample will repeat endlessly. At lower magnitudes the sample will repeat and fade out over time. Use this parameter to create a "cascading" chorus effect.

Range: -1.0 to 1.0

Definition at line 387 of file effectparameters.h.

Integer Mezzanine::Audio::ChorusParameters::Phase

This property controls the phase difference between the left and rightLow Frequency Oscillation's.

Remarks

At zero degrees the two LFOs are synchronized. Use this parameter to create the illusion of an expanded stereo field of the output signal.

Range: -180 to 180

Definition at line 377 of file effectparameters.h.

Real Mezzanine::Audio::ChorusParameters::Rate

This property sets the modulation rate of the Low Frequency Oscillation that controls the delay time of the delayed signals.

Remarks

Range: 0.0 to 10.0

Definition at line 380 of file effectparameters.h.
