Match EQ parameters in Logic Pro for iPad

Match EQ offers the parameters described in this section.

Match EQ parameters

Current Material Learn button: Start or stop the process of learning the frequency spectrum of the project you want to match with the source file or input.
Reference Material Learn button: Start or stop the process of learning the frequency spectrum of the source file or input.
Crnt/Ref Actions pop-up menus: Choose and execute commands from either the Current or Reference Actions pop-up menu.
- Clear Current Material/Reference Spectrum: Clears the Current Material Spectrum or Reference Spectrum.
- Copy Current/Reference Spectrum: Copies the Current Material Spectrum or Reference Spectrum to the Clipboard.
- Paste Current/Reference Spectrum: Pastes the Current Material Spectrum or Reference Spectrum from the Clipboard.
Match button: Match the frequency spectrum of the current material to that of the template (source) file.
Phase pop-up menu: Choose the operational principle of the filter curve.
- Linear: Prevents processing from altering the signal phase, but latency is higher.
- Minimal: Alters the signal phase (slightly), but latency is reduced.
- Minimal, Zero Latency: Adds no latency, but has a higher CPU overhead than the other options.
Channel Link knob: Change the way the EQ curve is applied to stereo channels.
- When set to 100%, both channels share a common EQ curve.
- When set to 0%, a separate filter curve is applied for the left and right channel.
- Settings between 0 and 100% blend these values with your filter curve changes for each channel. This results in a hybrid curve.
  Note: The Channel Link parameter is disabled when you use the effect on a mono channel.
Smoothing knob and field: Set the amount of smoothing for the filter curve, using a constant bandwidth set in semitone steps. A value of 0.0 has no impact on the filter curve. A value of 1.0 means a smoothing bandwidth of one semitone. A value of 4.0 means a smoothing bandwidth of four semitones (a major third). A value of 12.0 means a smoothing bandwidth of one octave, and so on.
Note: Smoothing has no effect on any manual changes you make to the filter curve.
Apply Amount slider and field: Determine the impact of the filter curve on the signal.
- Values above 100% magnify the effect.
- Values below 100% reduce it.
- Negative values (−1% to −100%) invert the peaks and troughs in the filter curve.
- A value of 100% has no impact on the filter curve.
Fade Extremes button: Select to set an automatic high cut and low cut threshold. Matching signals above or below these thresholds are slowly faded to zero.
Fade LF Bottom/Top sliders: Set the bottom and top frequencies for the filter curve that is applied to low frequency spectrum signals.
Fade HF Bottom/Top sliders: Set the bottom and top frequencies for the filter curve that is applied to high frequency spectrum signals.
