Glossary 585
filter effect Filters are effects you can apply to Audio or MIDI Regions (when streamed
or recorded as audio). They are designed to reduce a signal’s energy at a specific
frequency. A true filter always acts as a subtractive device, and doesn’t add anything to
the signal. The names of the individual filters illustrate their function. As an example: A
Low Pass filter allows frequencies that are lower than the cutoff frequency to pass.
Filter button Buttons in the Event List/Track Mixer, that allow you to hide/show
specific event types/channel strip types.
filter slope The filter slope is the steepness, or severity, of filter attenuation. As
examples, a filter slope of 6 dB per octave would sound much softer than a filter slope
of 12 dB per octave.
flanger The flanger effect is similar to the chorus effect, where a slightly delayed signal
(which is shorter than that of the Chorus) is fed back into the delay line input. Flanging
makes a sound thicker, and slightly “out of phase”.
float window Window with special status which always “floats” on the surface above
all other windows, but can only be operated with the mouse. Any Logic window can be
opened as a float window by holding down Option while opening it.
frame Unit of time. A second in the SMPTE standard is divided into frames that
correspond to a single still image in a file or video.
Freeze function The Freeze function performs individual offline bounce processes for
each “frozen” track, saving almost 100% of the CPU power used for software
instruments and effect plug-ins. All plug-ins of a track (including software instrument
plug-ins, if applicable, along with all related automation data) are rendered into a
“Freeze file”. You can use the Freeze function on individual Audio or Audio Instrument
tracks.
frequency The number of times a sound signal vibrates each second, measured in
cycles per second, or Hertz (Hz).
grab (an object) Positioning the mouse cursor over an object, then pressing and
holding the mouse button down.
help tag A small text window that appears when the mouse cursor is placed over an
interface element that indicates the name or value. When editing operations such as
moving or cutting a Region are performed, a larger help tag will display the current
position of the Region or function—in realtime.
Hermode Tuning A microtonal tuning system that can be used on all Logic and Audio
Unit software instruments. Hermode Tuning can make your software instruments
sound harmonically richer by fine tuning thirds, fifths and sevenths to specific
intervals—in cents.
