PYLE Audio PLTTB3U - Manual (Page 12)

12
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).
[MENU]
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.
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.
