Export as MP3: exports audio as an MP3 file. As MP3 files are compressed, they
use less disk space, but they lose some audio quality. Another compress alternative
is Ogg Vorbis (see below). You can set the quality of MP3 compression in the File
Format Preferences. See also MP3 Exporting.
Export Selection as MP3: same as above, but only exports the current selection.
Export as Ogg Vorbis: exports all audio as an Ogg Vorbis file. Ogg Vorbis files are
compressed files, and therefore use less disk space, but they do lose some audio
quality. Ogg Vorbis files use a little less disk space then MP3 files but have similar
compression quality. Furthermore, Ogg Vorbis is free from patents and licensing
restrictions. However, Ogg Vorbis files are not as widespread as MP3. 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: “label track”, if activated, lets you export labels as text files. 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 in just one step. You can
either split them vertically (one new file per track), or horizontally (using labels in a
“label track” to indicate breaks between exported files.
Page Setup: configures how Audacity will print the track waveforms using the “print”
option, and which printer to use.
Print: prints the main window view from Audacity, showing tracks and waveforms.
Exit (Quit): closes all windows and exits Audacity, prompting you to save any
unsaved changes first.
The “Edit” Menu
Undo: undoes the last editing operation you performed in your project. Audacity
supports full-unlimited undo; meaning you can undo every editing operation you
made during a session.
Redo: redoes any editing operation that was 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 stores it on the clipboard. Only one project
can be on the clipboard at a time, but that project may contain multiple tracks.
Copy: copies selected audio data to the clipboard without removing it from the
project.
