Audacity Portable is the popular Audacity audio editor packaged as a portable app, so you can take your audio files along with everything you like....
2. Audacity projects:
Are stored as multiple files: an AUP master file and
numerous small audio files in subfolders.
May save some space by referencing original audio
material rather than making a copy (dependencies).
Your project will no longer work if you overwrite or
move the original audio file(s) on which it depends!
If you want your audio in standard formats like WAV,
you must export it because you can't use AUP for this.
3. Audacity projects contain audio clips arranged onto
tracks along with additional information.
The project's structure is stored in an AUP file, with
audio and housekeeping information in numerous small
files in a folder in the same directory as the AUP file.
For example, if you have a project named "MyProject"
there will be a file called "MyProject.aup" and
a folder called "MyProject_data".
4. Whilst this Audacity Project Format makes working with
the audio more rapid, the format is not compatible with
any other audio program.
When you Save an Audacity project, you save in
the Audacity Project Format, i.e. as an AUP file. The AUP
file cannot be used in an MP3 player.
If you have audio which you want to use in Audacity but
which wasn't recorded in Audacity, you will usually need
to Import the audio. This is also an option on the File
Menu.
5. 1)
Never rename the .aup file or the _data folder.
2)
If you want to rename your project (for example, to save a
snapshot at a particular point), use the File > Save Project
As command.
3)
Always keep the .aup file and the _data folder together in the
same directory (folder).
If you import an audio file with the "Read uncompressed file
directly from the original (faster)" option checked in Import /
Export Preferences, never move, rename or delete that file,
unless you first copy it into the Audacity project. See File > Check
Dependencies for more information.
6. When you open or import an uncompressed audio file such as WAV or
AIFF, Audacity saves time by not making a copy of the file. Instead, it
refers back to the original file as you manipulate it within your project
(while not ever making any changes to that file unless you tell it to).
You must be careful not to modify files that you have open in Audacity
with another program.
When you save an Audacity project, Audacity will tell you about these
dependencies and give you the option of copying all of the audio data into
your Audacity project, making it safe to delete, move, or modify the
original audio files if you choose.
At any time, click on File > Check Dependencies... to see if your project
depends on any external files.
7. To use the audio outside Audacity, you Export the audio
into another format, as described on the File Menu.
The format you need will depend on how you plan to use
the audio.
For an MP3 player you will want MP3 format.
For burning to a CD you will want WAV format.
