Exciter in Logic Pro for iPad
Exciter generates high frequency components that are not part of the original signal. It does this by utilizing a nonlinear distortion process that resembles the one used to produce overdrive and distortion effects.
Unlike this process, however, the Exciter distortion process involves passing the input signal through a highpass filter before feeding it into the harmonics (distortion) generator. Artificial harmonics are thus added to the original signal, and these added harmonics contain frequencies at least one octave above the threshold of the highpass filter. The distorted signal is then mixed with the original, dry signal.
You can use Exciter to add life to recordings, particularly audio tracks with a weak treble frequency range. You can also use Exciter to enhance guitar tracks.
To add Exciter to your project, choose Specialized > Exciter 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.
Exciter parameters
Dry Signal button: Turn on to mix the original (pre-effect) signal with the effect signal. Turn off to hear only the effect signal.
Color 1 and 2 buttons: Turn on Color 1 to generate a less dense harmonic distortion spectrum. Color 2 generates more intense harmonic distortion.
Note: Color 2 also introduces more intermodulation distortions, which can result in unpleasant artifacts.
Frequency knob and field: Set the cutoff frequency of the highpass filter. The input signal passes through the filter before (harmonic) distortion is introduced.
Harmonics knob and field: Set the ratio between the effect and the original signals. If the Dry Signal button is turned off, this parameter has no effect.
Note: In most cases, it is preferable to select higher Frequency and Harmonics values, because human ears cannot easily distinguish between the artificial and original high frequencies.
