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, it 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.
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 CDs 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).
[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.
