El nombre "Phaser" viene de "Cambiador de fase", porque funciona combinando señales de fase cambiada con la señal original. El movimiento de las señales con la fase cambiada es controlado usando un oscilador de baja frecuencia (LFO).

La interacción de la señal con la fase cambiada y la señal original crea un efecto de filtro de barrido de muesca que suena similar pero más sutil que un efecto flanger.

Diálogo de cambio de fase
Advice La salida de este efecto puede tener una amplitud mayor que el audio original. Si el nivel de salida excede los 0 dB (la altura completa de la pista) será recortada y creará una distorsión no placentera que no podrá ser reparada. Si esto ocurre, deshaga el efecto y amplifique el audio a un nivel menor antes de aplicar Cambio de fase.

Etapas

The Phaser effect consists of a series of filters that each produce a frequency-dependent delay. By mixing some of the original signal with the delayed signal, phase cancellation will occur at a particular frequency, creating a marked notch (reduction in level) at that frequency. When the original and delayed signals are "in phase" with each other, that frequency will be boosted to a higher level, creating a peak at that frequency. Each "stage" in the effect adds more notches and peaks in the frequency response, giving more complexity to the sound.

Seco/Húmedo

When set to 0, only the "Dry" (unprocessed) signal is produced. When set to 255 (maximum), only the delayed signals are produced. Because the effect's sound results from phase interaction, the effect sounds strongest when the Dry/Wet mix is set at the default halfway position (128).

Frecuencia LFO (Hz)

This is a low frequency oscillator (LFO) control that adjusts the rate at which the effect sweeps up and down across the frequency range.

Fase de inicio LFO Start Phase (deg.)

The start position of the low frequency oscillator is adjustable between 0 and 360 degrees. When set at zero (the default) the filters begin sweeping from high frequency down to low frequency. When set at 180 degrees, the filters begin by sweeping up from low frequency.

Profundidad

The depth control governs how high the filter frequencies sweep. At a low setting the phaser will primarily affect bass frequencies. At higher settings the phaser effect can sweep high into the treble.

Retroalimentación (%)

By adjusting the feedback control, the processed signal can be passed back through the effect, creating a more pronounced effect. At high settings, the effect will become highly resonant, similar to a Wahwah effect. At negative settings. an inverted signal is fed back into the effect, creating another variant of the effect.

Advice At maximum or minimum feedback settings, the effect becomes unstable and will create massive distortion.
