moves upwards: Turn the counterweight counter-clockwise. If the tone
arm moves downwards: Turn the counterweight clockwise.
5) Put the tone arm back onto the arm rest and lock it.
6) The counterweight is with a rotary ring with a scale. The white line on
the tone arm points to a value on this scale. Without turning the
counterweight, only turn the ring to “0”
7) The scale indicates the stylus pressure in grams. The pressure of the
stylus supplied with this turntable is 3 g, turn the counterweight
counter-clockwise to “2.5”. If another stylus is used, adjust the stylus
pressure indicated in the corresponding specifications of the stylus.
8) Adjusting the anti-skating facility
When playing a record, forces occur on the stylus which are
compensated by the anti-skating facility. For this purpose, adjust the
anti-skating knob from “0” to the value equals to the stylus pressure,
with for the supplied stylus system , it’s “2.5”.

Track Pop-Down Menu
The Track Pop-Down Menu appears when you click in a track's title. This
lets you access a few special commands that apply to individual tracks.
Name... - lets you change the name of the track.
Move Track Up - exchange places with the track above this one.
Move Track Down - exchange places with the track below this one.
Waveform - sets the display to Waveform - this is the default way of
visualizing audio.
Waveform (dB) - similar to Waveform, but on a logarithmic scale,
measured in decibels (dB).
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.
Mono - makes this track a mono track, meaning it is played out of just one
speaker, or played out of the left and right speakers equally.
Left Channel - makes this track come out of only the left speaker.
Right Channel - makes this track come out of only the right speaker.
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.

15
Split Stereo Track - if the selected track is a stereo track (a pair of left and
right tracks joined together as a single track), this operation splits them into
two separate tracks that you can modify and edit independently.
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.
Set Rate - sets the number of samples per second of the track. 44100 Hz
is used by audio CDs. Tracks can have different sample rates in Audacity;
they are automatically resampled to the project sample rate (in the lower-
left corner of the window).
File Menu
New - creates a new empty window
Open... - opens an audio file or an Audacity project in a new window
(unless the current window is empty). To add audio files to an existing
project window, use one of the Import commands in the Project menu.
Close - closes the current window, asking you if you want to save changes.
On Windows and Unix, closing the last window will quit Audacity, unless
you modify this behavior in the Interface Preferences.
Save Project - saves everything in the window into an Audacity-specific
format so that you can save and quickly continue your work later. An
Audacity project consists of a project file, ending in ".aup", and a project
data folder, ending in "_data". For example, if you name your project
"Composition", then Audacity will create a file called "Composition.aup"
and a folder called Composition_data. Audacity project files are not meant
to be shared with other programs - use one of the Export commands
(below) when you are finished editing a file.
Save Project As... - same as Save Project (above), but lets you save a
project as a new name.
Recent Files ... - brings up a list of files you have recently opened in
audacity to be re-opened quickly.

16
Export As WAV... - exports all of the audio in your project as a WAV file,
an industry-standard format for uncompressed audio. You can change the
standard file format used for exporting from Audacity by opening the File
Format Preferences . Note that exporting will automatically mix and
resample if you have more than one track, or varying sample rates. See
also File Formats.
Export Selection As WAV... - same as above, but only exports the current
selection.
Export as MP3... - exports all of the audio as an MP3 file. MP3 files are
compressed and therefore take up much less disk space, but they lose
some audio quality. Another compressed alternative is Ogg Vorbis (below).
You can set the quality of MP3 compression in the File Format Preferences.
See alsoMP3 Exporting.
Export Selection As MP3... - same as above, but only exports the current
selection.
Export as Ogg Vorbis... - exports all of the audio as an Ogg Vorbis file.
Ogg Vorbis files are compressed and therefore take up much less disk
space, but they lose some audio quality. Ogg Vorbis files tend to take up a
little less disk space than MP3 for similar compression quality, and Ogg
Vorbis is free from patents and licensing restrictions, but Ogg Vorbis files
are not as widespread. You can set the quality of Ogg compression in the
File Format Preferences.
Export Selection As Ogg Vorbis... - same as above, but only exports the
current selection.
Export Labels... - if you have a Label Track in your project, this lets you
export the labels as a text file. You can import labels in the same text
format using the "Import Labels..." command in the Project Menu.
Export Multiple... - lets you split your project into multiple files all in one
step. You can either split them vertically (one new file per track), or
horizontally (using labels in a Label Track to indicate the breaks between
exported files.
Page Setup - configure how Audacity will print out the track waveforms
using the Print option, and what printer to use.

17
Print - Print out the main window view from audacity showing the tracks
and waveforms.
Exit (Quit) - closes all windows and exits Audacity, prompting you to save
any unsaved changes first.
Edit Menu
Undo - This will undo the last editing operation you performed to your
project. Audacity supports full unlimited undo - meaning you can undo
every editing operation back to when you opened the window.
Redo - This will redo any editing operations that were just undone. After
you perform a new editing operation, you can no longer redo the
operations that were undone.
Cut - Removes the selected audio data and places it on the clipboard.
Only one "thing" can be on the clipboard at a time, but it may contain
multiple tracks.
Copy - Copies the selected audio data to the clipboard without removing it
from the project.
Paste - Inserts whatever is on the clipboard at the position of the selection
or cursor in the project, replacing whatever audio data is currently selected,
if any.
Trim - Removes everything to the left and right of the selection.
Delete - Removes the audio data that is currently selected without copying
it to the clipboard.
Silence - Erases the audio data currently selected, replacing it with silence
instead of removing it.
Split - Moves the selected region into its own track or tracks, replacing the
affected portion of the original track with silence. See the figure below:

18
Duplicate - Makes a copy of all or a part of a track or set of tracks into new
tracks. See the figure below:
Select ... > All - Selects all of the audio in all of the tracks in the project.
Select ... > Start to Cursor - Selects from the beginning of the selected
tracks to the cursor position.
Select ... > Cursor to End - Selects from the cursor position to the end of
the selected tracks.
Find Zero Crossings - Modifies the selection slightly so that both the left
and right edge of the selection appear on a positive-slope zero crossing.
This makes it easier to cut and paste audio without resulting in an audible
clicking sound.
Selection Save - Remembers the current selection (or cursor position),
allowing you to restore it later.
Selection Restore - Restores the cursor position to the last position saved
by "Selection Save".
Move Cursor ... > to Track Start - Moves the cursor to the start of the
current track.
Move Cursor ... > to Track End - Move the cursor to the end of the
currently selected track.
Move Cursor ... > to Selection Start - Moves the cursor to the start of the
current selection.
Move Cursor ... > to Selection End - Moves the cursor to the end of the
current selection.
Snap-To ... > Snap On - Enable Snap-To mode. When Snap-To mode is
enabled, the selection will be constrained to the nearest interval on the
time scale, by default the nearest second. So if you click and drag from 4.2
seconds to 9.8 seconds, it will result in a selection from 4 seconds to 10

19
seconds, exactly. You can change the units that are snapped to using the
"Set Selection Format" option in the View Menu .
Snap-To ... > Snap Off - Turns Snap-To mode off letting you select
arbitrary ranges of time
Preferences... - Opens the preferences dialog.
View Menu
Zoom In - Zooms in on the horizontal axis of the audio, displaying more
detail about less time. You can also use the zoom tool to zoom in on a
particular part of the window.
Zoom Normal - Zooms to the default view, which displays about one inch
per second.
Zoom Out - Zooms out, displaying less detail about more time.
Fit in Window - Zooms out until the entire project just fits in the window.
Fit Vertically - Resizes all of the tracks vertically so they all fit inside of the
window (if possible).
Zoom to Selection - Zooms in or out so that the selection fills the window.
Set Selection Format - lets you choose the formatting that is displayed at
the bottom of the window indicating the current selection time. Options
include film, video, and audio CD frames, seconds + samples, or pure time.
If you turn on Snap-To mode in the Edit Menu, the selection will snap to
the frames or other quantization you have selected in this menu.
History... - Brings up the history window. It shows all the actions you have
performed during the current session, including importing. The right-hand
column shows the amount of hard disk space your operations used. You
can jump back and forth between editing steps quite easily by simply
clicking on the entries in the window, the same as selecting Undo or Redo
many times in a row. You can also discard Undo history to save disk space.
The history window can be kept open while you work.
Float Control Toolbar - moves the Control Toolbar out of the window and
into its own floating window, so you can position it wherever you want. The

20
menu item changes to Dock Control Toolbar, which you can use to put
the toolbar back into the main window.
Float Edit Toolbar - moves the Edit Toolbar out of the window and into its
own floating window, so you can position it wherever you want. The menu
item changes to Dock Edit Toolbar, which you can use to put the toolbar
back into the main window.
Float Meter Toolbar - does the same thing for audacity's VU meters which
you use to set recording levels and adjust playback.
Float Mixer Toolbar - moves the Mixer Toolbar out of the window and into
its own floating window as above.
Project Menu
Import Audio... - This command is used to 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 tracks.
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 listen 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 the file's header, which Audacity was not able to
parse. Just zoom in and select the noise with the Selection Tool, and then
choose Delete from the Edit Menu.
Edit ID3 Tags... - Opens a dialog allowing you to edit the ID3 tags
associated with a project, for MP3 exporting.
