audacity [-blocksize nnn] [ AUDIO-FILE ] ...
Audacity is a graphical audio editor. This man page does not describe
all of the features of Audacity or how to use it; for this, see the
html documentation that came with the program, which should be
accessible from the Help menu. This man page describes the Unix-
specific features, including special files and environment variables.
Audacity currently uses libsndfile to open many uncompressed audio
formats such as WAV, AIFF, and AU, and it can also be linked to libmad,
libvorbis, and libflac, to provide support for opening MP2/3, Ogg
Vorbis, and FLAC files, respectively. LAME, libvorbis, libflac and
libtwolame provide facilities to export files to all these formats as
Audacity is primarily an interactive, graphical editor, not a batch-
processing tool. Whilst there is a basic batch processing tool it is
experimental and incomplete. If you need to batch-process audio or do
simple edits from the command line, using sox or ecasound driven by a
bash script will be much more powerful than audacity.

Per user configuration file.
Default location of Audacity’s temp directory, where <user> is
your username. If this location is not suitable (not enough
space in /tmp, for example), you should change the temp
directory in the Preferences and restart Audacity. Audacity is
a disk-based editor, so the temp directory is very important: it
should always be on a fast disk with lots of free space.
Note that older versions of Audacity put the temp directory
inside of the user’s home directory. This is undesirable on
many systems, and using some directory in /tmp is recommended.
Open the Preferences to check.
When looking for plug-ins, help files, localization files, or other
configuration files, Audacity searches the following locations, in this
Any directories in the AUDACITY_PATH environment variable will
be searched before anywhere else.
The current working directory when Audacity is started.
The system-wide Audacity directory, where <prefix> is usually
/usr or /usr/local, depending on where the program was
The system-wide Audacity documentation directory, where <prefix>
is usually /usr or /usr/local, depending on where the program
For localization files in particular (i.e. translations of Audacity
into other languages), Audacity also searches <prefix>/share/locale
Audacity supports two types of plug-ins on Unix: LADSPA and Nyquist
plug-ins. These are generally placed in a directory called plug-ins
somewhere on the search path (see above).
LADSPA plug-ins can either be in the plug-ins directory, or
alternatively in a ladspa directory on the search path if you choose to
create one. Audacity will also search the directories in the
LADSPA_PATH environment variable for additional LADSPA plug-ins.
Nyquist plug-ins can either be in the plug-ins directory, or
alternatively in a nyquist directory on the search path if you choose
to create one.

Project leaders include Dominic Mazzoni, Matt Brubeck, James Crook,
Vaughan Johnson, Leland Lucius, and Markus Meyer, but dozens of others
have contributed, and Audacity would not be possible without wxWindows,
libsndfile, and many of the other libraries it is built upon. For the
