Phase Distortion in Logic Pro for iPad
The Phase Distortion effect is based on a modulated delay line, similar to a chorus or flanger effect (see Modulation effects). Unlike these effects, however, the delay time is not modulated by a low frequency oscillator (LFO) but rather by a lowpass-filtered version of the input signal itself, using an internal side chain. This means that the incoming signal modulates its own phase position.
The input signal only passes the delay line and is not affected by any other process. The Mix parameter blends the effect signal with the original signal.
To add Phase Distortion to your project, choose Distortion > Phase Distortion in a channel strip Audio Effect plug-in menu or the Plug-ins area. See Intro to plug-ins. Also see Add, replace, reorder, and remove plug-ins in the Plug-ins area and Work with plug-ins in the Mixer.
Phase Distortion parameters
Cutoff knob and field: Set the (center) cutoff frequency of the lowpass filter.- Resonance knob and field: Emphasize frequencies surrounding the cutoff frequency.
Monitor button: Turn on to hear the input signal in isolation. Turn off to hear the mixed signal.
- Intensity knob and field: Set the amount of modulation applied to the signal.
Delay knob and field: Set the maximum delay time.
Phase Reverse button: Turn on to reduce the delay time on the right channel when input signals that exceed the cutoff frequency are received. Available only for stereo instances of the Phase Distortion effect.
Mix slider and field: Set the percentage of the effect signal mixed with the original signal.
