import audio from a 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

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 options in the dialog
to try some other possible encodings.
At the beginning of your imported track(s), you
may notice a little bit of noise. This is probably

New Stereo Track – same as above, but
creates a stereo track. You can also create a
stereo track by joining two tracks using the
track pop-down menu.
New Label Track – This creates a new Label
Track, which can be very useful for textual
Edit ID3 Tags… - Opens a dialog allowing
you to edit the ID3 tags associated with a
project, for MP3 exporting.
New Time Track – This creates a new Time
Track, which is used to vary the speed of
playback over time.
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
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.

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
Align Tracks - All the Align funtions 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
cursor” below.
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.
Add Label at Selection – This menu item
lets you create a new label at the current
selection. You can titile the label by typing with
the keyboard and then hitting “Enter” when
you’re done.
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 the audacity is playing.
Any items which appear after these three
built-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.
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.
Generate Menu
Repeat Last Effect – selecting this
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

Silence – inserts silence
command is a shortcut to applying the most
recent effect with the same settings. This is a
convenient way to quickly apply the same
effect to many different parts of a file.
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 amplify so that
the loudest part of the selection is as loud as
possible without distortion.
Tone… - you can create a Sine wave, Square
wave, or Sawtooth wave.
Bass Boost – enhances the bass frequencies
in the audio.
White Noise – inserts random audio samples,
which sounds like purestatic.
Change Pitch – changes the pitch/frequency
of the selected audio without changing the
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.
your own curve.
Fade In – fades the selection in linearly.
Fade Out – fades the selection out
FFT Filter – similar to Equalization, lets you
enhance or reduce arbitrary frequencies. The
curve here uses a linear scale for frequency.
Change Speed – changes the speed of the
audio by re-sampling. Making the speed higher
will also increase the pitch, and vice versa. This
will change the length of the selection.
Invert – Flips the waveform vertically, the
same as a phase inversion in the analogue
Change Tempo – changes the tempo (speed)
of the audio without changing the pitch. This
will change the length of the selection.
Compressor – compresses the dynamic
range of the selection so that the loud parts are
soft parts the same. You can optionally
normalize the recording afterwards, resulting in
the entire piece having higher perceived
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.
Echo – very simple effect that repeats the
selection with 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
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.
Analyze Menu
Plot Spectrum – To use this feature, first
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
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.
select a region of audio from a single track, and
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 Auto correlation
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
throughout the frequency spectrum. Adjust 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.
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
Help Menu
