.SH DESCRIPTION

.B 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

.B libsndfile

to open many uncompressed audio formats such as WAV,

AIFF, and AU, and it can also be linked to

.B libmad,

.B libvorbis,

and

.B libflac,

to provide support for opening MP2/3, Ogg Vorbis, and FLAC files,

respectively.

.B LAME, libvorbis, libflac

and

.B libtwolame

provide facilities to export files to all these formats as well.

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

.B sox

or

.B ecasound

driven by a bash script will be much more powerful than audacity.

.SH FILES

.I ~/.audacity\-data/audacity.cfg

.RS

Per user configuration file.

.RE

.I /var/tmp/audacity\-<user>/

.RS

Default location of Audacity's temp directory, where <user> is your

username. If this location is not suitable (not enough space in

/var/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 (local) 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.

On many modern Linux systems all files in /tmp/ will be deleted

each time the system boots up, which makes recovering a recording

that was going on when the system crashed much harder. This is why

the default is to use a directory in /var/tmp/ which will not

normally be deleted by the system. Open the Preferences to check.

.RE

.SH SEARCH PATH

When looking for plug-ins, help files, localization files, or other

configuration files, Audacity searches the following locations, in

this order:

.I AUDACITY_PATH

.RS

Any directories in the

.I AUDACITY_PATH

environment variable will be searched before anywhere else.

.RE

.I .

.RS

The current working directory when Audacity is started.

.RE

.I ~/.audacity-data/Plug-Ins

.I <prefix>/share/audacity

.RS

The system-wide Audacity directory, where <prefix> is usually

/usr or /usr/local, depending on where the program was installed.

.RE

.I <prefix>/share/doc/audacity

.RS

The system-wide Audacity documentation directory, where <prefix> is usually

/usr or /usr/local, depending on where the program was installed.

.RE

For localization files in particular (i.e. translations of Audacity

into other languages), Audacity also searches

.I <prefix>/share/locale

.SH PLUG\-INS

Audacity supports two types of plug-ins on Unix: LADSPA and Nyquist

plug-ins. These are generally placed in a directory called

.I plug\-ins

somewhere on the search path (see above).

LADSPA plug-ins can either be in the plug-ins directory, or alternatively

in a

.I ladspa

directory on the search path if you choose to create one. Audacity will

also search the directories in the

.I LADSPA_PATH

environment variable for additional LADSPA plug-ins.

Nyquist plug-ins can either be in the plug-ins directory, or alternatively

in a

.I nyquist

directory on the search path if you choose to create one.

.SH AUTHORS

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 wxWidgets, libsndfile, and many of

the other libraries it is built upon. For the most recent list
