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). 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.
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.
Help Menu
About Audacity - displays the version number
and credits. If you compiled Audacity yourself,
check here to verify which optional modules
were successfully compiled in.
