Make Stereo Track - if there is
another track below this one, joins
them to make a single stereo track,
with the top track representing the
left speaker, and the bottom track
representing the right speaker.
When tracks are joined into a stereo
pair, all edits automatically apply to
both the left and right channel.

Waveform (dB) - similar to
Waveform, but on a logarithmic
scale, measured in decibels (dB).
Set Sample Format - this
determines the quality of the audio
data and the amount of space it
takes up. 16-bit is the quality used
by audio CD's and is the minimum
quality that Audacity uses internally
(8-bit audio files are automatically
converted when you open them).
24-bit is used in higher-end audio
hardware. 32-bit float is the highest
quality that Audacity supports, and
it is recommended that you use 32-
bit float unless you have a slow
computer or are running out of disk
space.
Spectrum - display the track as a
spectrogram, showing the amount
of energy in different frequency
bands.
Pitch (EAC) - highlights the contour
of the fundamental frequency
(musical pitch) of the audio, using
the Enhanced Autocorrelation (EAC)
algorithm.

standard audio format into your
project. Use this command if you
already have a couple of tracks and
you want to add another track to the
same project, maybe to mix them
together. You cannot use this option
to import Audacity Projects. The
only way to combine two Audacity
Projects is to open them in separate
windows, then copy and paste the
tracks.
Quick Mix - This command mixes
all of the selected tracks together. If
you are mixing stereo tracks, or
mixing tracks that are marked as
Left or Right channel, the result will
be a stereo track (two channels),
otherwise the result will be mono.
Your tracks are implicitly mixed
whenever you hit the Play button
and whenever you export. This
command offers a way to do it
permanently and save the results to
disk, saving on playback resources.
Note that if you try to mix two very
loud tracks together, you may get
clipping (it will sound like pops,
clicks, and noise). To avoid this,
drag the gain slider on the tracks
down to reduce their volume before
mixing.
Import Labels... - This command
takes a text file which contains time
codes and labels, and turns them
into a Label Track.
Import MIDI... - This menu
command imports MIDI files and
puts them into a MIDI Track.
Audacity can display MIDI files, but
cannot play, edit, or save them yet.
Import Raw Data... - This menu
command allows you to open a file
in virtually any uncompressed
format. When you select the file,
Audacity will analyze it and try to
guess its format. It will guess
correctly about 90% of the time, so
you can try just pressing "OK" and
listening to the result. If it is not
correct, however, you can use the
New Audio Track - This creates a
new empty Audio Track. This
command is rarely needed,since
importing, recording, and mixing
automatically create new tracks as
needed. But you can use this to cut
or copy data from an existing track
and paste it into a blank track. If

that track was at a non-default rate
then you may need to use Set Rate
from the Track Pop-Down menu to
set the correct sample rate.
Align and move cursor... - same
as the functions above, except that
the cursor or selection is moved
along with the tracks. That allows
you to shift the tracks without losing
your relative place.
New Stereo Track - same as
above, but creates a stereo track.
You can also create a stereo track
Add Label at Selection - This

pop-down menu.
label at the current selection. You
can title the label by typing with the
keyboard and then hitting "Enter"
when you're done.
New Label Track - This creates a
new Label Track, which can be very
useful for textual annotation.
Add Label at Playback Position -
This menu item lets you create a
new label at the current location
where you are playing or recording.
Do this if you want to mark a certain
passage while you're listening to it.
You can title the label by typing with
the keyboard and then hitting
"Enter" or "Return" when you're
done. Only available whilst audacity
is playing.
New Time Track - This creates a
new Time Track, which is used to
vary the speed of playback over
time.
Remove Tracks - This command
removes the selected track or
tracks from the project. Even if only
part of a track is selected, the entire
track is removed. You can also
delete a track by clicking the X in its
upper-left corner. To cut out only
part of the audio in a track, use
Delete or Silence.
Generate Menu
If you choose an item from the
Generate menu when there are no
tracks in a project, a new track is
created. Otherwise, the current
track is used.
If a track is selected and the cursor
is placed in a single place in the
track audio is inserted at the cursor
position. The default duration is 30
seconds.
The audio created will replace the
any selection, otherwise it is
inserted into the track, shifting up
later parts of the track.
Align Tracks... - All the Align
functions work on whole tracks or
groups of tracks, not on selections,
even if they span across multiple
tracks. They all operate by time-
shifting tracks (moving them left or
right), making it easier to
synchronize tracks or get rid of
silence at the beginning. The cursor
or selection stays in the same place
unless you use "Align and move

way to quickly apply the same effect
to many different parts of a file.
Silence - inserts silence
Tone... - you can create a Sine
wave, Square wave, or Sawtooth
wave.
Amplify - changes the volume of
the selected audio. If you click the
"Allow clipping" checkbox, it will let
you amplify so much that the audio
ends up beyond the range of the
waveform, and is clipped (distorted).
The default value when you open
the effect is to amplifiy so that the
loudest part of the selection is as
loud as possible without distortion.
White Noise - inserts random audio
samples, which sounds like pure
static.
Any items which appear after these
three built-ins are VST, Ladspa, or
Nyquist plug-ins. It is possible for a
poorly written plug-in to crash
Audacity, so always save your work
before using a plug-in. Note that
any effect that doesn't take any
audio as input will automatically be
placed in the Generate menu.
Bass Boost - enhances the bass
frequencies in the audio.
Change Pitch - changes the
pitch/frequency of the selected
audio without changing the tempo.
When you open the dialog, the
starting frequency is set to
Audacity's best guess as to the
frequency of the selection. This
works well for recordings of singing
or musical instruments without
background noise. You can specify
the pitch change in one of four
different ways: musical note,
semitones, frequency, or percent
change.
Effect Menu
The items in this menu only work
when you have audio selected.
Audacity does not have any real-
time effects; you must select the
audio, apply the effect, and then
listen to the results.
Most effects have a Preview button.
Clicking on this button plays up to
three seconds of audio, allowing
you to hear what it will sound like
after the effect is applied. This is
useful for fine-tuning the effect
parameters.
Change Speed - changes the
speed of the audio by resampling.
Making the speed higher will also
increase the pitch, and vice versa.
This will change the length of the
selection.
Repeat Last Effect - selecting this
command is a shortcut to applying
the most recent effect with the
Change Tempo - changes the
tempo (speed) of the audio without

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).
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, -3 dB.
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.
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.
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.
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.
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).
Invert - Flips the waveform
vertically, the same as a phase
inversion in the analogue domain.

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.

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.
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
