Equalizers
Logic Pro Equalizers overview
An equalizer (commonly abbreviated as EQ) shapes the sound of incoming audio by
changing the level of specific frequency bands.
Equalization is one of the most-used audio processes, both for music projects and in
post-production work for video. You can use EQ to subtly or significantly shape the
sound of an audio file, an instrument, a vocal performance, or a project by adjusting
specific frequencies or frequency ranges.
All EQs are specialized filters that allow certain frequencies to pass through unchanged
while raising (boosting) or lowering (cutting) the level of other frequencies. Some EQs can
be used in a “broad-brush” fashion, to boost or cut a large range of frequencies. Other
EQs, particularly parametric and multiband EQs, can be used for more precise control.
The simplest types of EQs are single-band EQs, which include low cut and high cut,
lowpass and highpass, shelving, and parametric EQs. See Logic Pro Single-Band EQ.
Multiband EQs such as Channel EQ or
Linear Phase EQ combine several filters in one unit,
enabling you to control a large part of the frequency spectrum. Multiband EQs let you
independently set the frequency, bandwidth, and Q factor of each frequency spectrum
band. This provides extensive and precise tone-shaping of any audio source, be it an
individual audio signal or an entire mix.
Some EQs, particularly vintage units, are known for the distinctive sonic coloration they
impart on the sound. See Logic Pro Vintage EQ collection overview.
Other EQs allow you to analyze incoming audio to capture a sonic “fingerprint” which
you can then apply to other audio material. See Logic Pro
Match EQ overview.
Channel EQ
Logic Pro Channel EQ overview
Channel EQ is a versatile multiband EQ. It provides eight color-coded frequency bands,
including lowpass and highpass filters, low and high shelving filters, and four flexible
parametric bands. It also features a Fast Fourier Transform (FFT) Analyzer that shows
real time changes to the frequency curve, allowing you to see which parts of the
frequency spectrum may need adjustment. See Logic Pro
Channel EQ parameters.
