Compressor; Echo; Equalization; Fade In - DigiTech GE4056 Instructions Manual

Compressor – compresses the
dynamic range of the selection so that
the loud parts are soft parts the same.
You can optionally normalise the
recording afterwards, resulting in the
entire piece having higher perceived
volume.
Echo – very simple effect that repeats
the selection with a decay, sounding
like a series of echos. This effect does
not change the length of the selection,
so you may want to add silence to the
end of the track before applying it
(using the Generate Menu).
Equalization – Boost or reduce
arbitrary frequencies. You can select
one of a number of different curves
designed to equalize the sound of
some popular record manufacturers,
or draw your own curve.
Fade In – fades the selection in
linearly.
Fade Out – fades the selection out
linearly.
FFT Filter – similar to Equalization,
lets you enhance or reduce arbitrary
frequencies. The curve here uses a
linear scale for frequency.
Invert – Flips the waveform vertically,
the same as a phase inversion in the
analogue domain.
Noise Removal – This effect lets you
clean up noise from a recording.
First, select a small piece of audio that
is silent except for the noise, select
" Noise Removal", and click on the
"Get Noise Profile" button.
Then select all of the audio you want
filtered select " Noise Removal" again,
and click the " Remove Noise" button.
You can experiment with the slider to
try to remove more or less noise. It is
normal for Noise Removal to result in
some distortion. It works best when
the audio signal is much louder than
the noise.
Normalize – allows you to correct for
DC offset (a vertical displacement of
the track) and/or amplify such that the
maximum amplitude is a fixed amount
-3Db. It's useful to normalize all of
your tracks before mixing. If you have
a lot of tracks, you may then need to
use the track gain sliders to turn some
down.
Nyquist Prompt – for advanced users
only. Allows you to express arbitrary
transormations using a powerful
functional programming language.
See the Nyquist section of the
Audacity website for more information.
Phaser – the name "Phaser" comes
from "Phase Shifter", because it works
by combining phase-shifted signals
with the original signal. The movement
of the phase-shifted signals is
controlled using a low Frequency
Oscillator (LFO).
