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.
