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).
Repeat - repeats the selection a certain number of times. This operation is
quite fast and space-efficient, so it is practical to use it to create nearly-
infinite loops.
Reverse - This effect reverses the selected audio temporally; after the
effect the end of the audio will be heard first and the beginning last.
Wahwah - uses a moving bandpass filter to create its sound. A low
frequency oscillator (LFO) is used to control the movement of the filter
throughout the frequency spectrum. It adjusts the phase of the left and
right channels when given a stereo selection, so that the effect seems to
travel across the speakers.
Plugins 1 to 15 ... etc. These submenus contain any VST, Ladspa, or
Nyquist plug-ins loaded by audacity. It is possible for a poorly written plug-
in to crash Audacity, so always save your work before using a plug-in
effect.
Analyze Menu
Plot Spectrum - To use this feature, first select a region of audio from a
single track, then select "Plot Spectrum". It opens up a window that
displays the Power Spectrum of the audio over that region, calculated
using the Fast Fourier Transform. The graph represents how much energy
is in each frequency. As you move the mouse over the display, it shows
you the nearest peak frequency. This window can also display other
common functions that are calculated using the Fast Fourier Transform,
including three versions of the Autocorrelation function. The Enhanced
Autocorrelation function is very good at identifying the pitch of a note.
The Analyze menu is intended for effects and plug-in effects that do not
modify the audio, but simply open a dialog with some descriptive
information. Audacity also supports Analyze commands that create
annotations in a Label Track.
