Audacity is built upon other free libraries; some of
these libraries may have come with Audacity in the lib-src
directory. Others you are expected to install first if
you want Audacity to have certain capabilities. Most
of these libraries are not distributed under the terms
of the GPL, but rather some other free, GPL-compatible
license. Specifically:
wxWindows: LGPL
Cross-platform GUI library - must be downloaded and
compiled separately.
expat: BSD-like license.
Provides XML parsing. Included with Audacity
iAVC: LGPL
Part of the code to the AVC Compressor effect.
Included with Audacity.
libid3tag: GPL
Reads/writes ID3 tags in MP3 files. Optional
separate download as part of libmad.
libmad: GPL
Decodes MP3 files. Optional separate download.
libnyquist: BSD-like license.
Functional language for manipulating audio; available
within Audacity for effects processing.
libogg: BSD-like license.
Optional separate download, along with libvorbis.
libsndfile: LGPL
Reads and writes uncompressed PCM audio files.
Included with Audacity.
libvorbis: BSD-like license.
Decodes and encodes Ogg Vorbis files. Optional
separate download.
For more information, see the documentation inside
each library's source code directory.
-------------------------------------------------------------
Compilation instructions:
First you must download wxWindows from:
http://www.wxwindows.org/
If you install the RPM, make sure you install the devel RPM
as well, otherwise, you won't be able to compile Audacity
from source.
To compile on Linux, Mac OS X, and other Unix systems,
simply execute these commands:
./configure
make
make install # as root
To see compile-time options you can set, you can type
"./configure --help".
If you want to do any development, you might want to generate
a configure cache and header dependencies:
./configure -C
make dep
To compile on Windows using MSVC++, please follow the
instructions found in compile.txt in the "win" subdirectory.
For more information on compilation (CodeWarrior for Mac is
also supported) please email audacity-help@lists.sourceforge.net

Known issues/problems:
* Windows: The floating tool palette does not minimize when
minimizing a project window. As a workaround, you can
just keep the tool palette docked with the project window.
-------------------------------------------------------------
New features in Audacity 1.1.3:
* User Interface
- New Mixer toolbar allows you to control the output
volume, input volume, and input source directly
from Audacity.
- Every track now has its own gain and pan controls.
* File I/O
- Fixed some bugs relating to reading/writing audio
files with more than 16 bits per sample.
* Audio I/O
- Completely rewritten audio I/O, with lower latency
and minimal chance of buffer underruns while
recording.
* Resampling
- Using high quality resampling algorithms, with the
option of better quality for mixing than for real-time
playback
- Preliminary support for Time Tracks, for changing
playback speed over time.
* Importing
- Import RAW is functional again, with a simpler GUI
but support for far more file formats. The
autodetection algorithms are much more accurate than
in 1.0.
* Many bug fixes and other features, too
New features in Audacity 1.1.2:
* User Interface
- Fixed bug in Windows version, for track menu commands
"Name..." and "Split Stereo Track"/"Make Stereo Track".
* Effects
- Nyquist support on Windows (supports plug-ins written
in Nyquist, an interpreted functional language based
on Lisp).
New features in Audacity 1.1.1:
* User Interface
- Tooltips appear in Statusbar.
- Vertical cursor follows play/record
- Pause button
- Drawing tool (with three different modes)
- Vertical Resizing of stereo tracks is more fun.
- Adjust selection by click-dragging selection boundary
- Toolbar button context-sensitive enabling/disabling
- Better zooming functionality (centers region)
- Multiple ways to display the cursor position and selection
- Snap-to selection mode
- Drag tracks up and down
- Align and group align functions
- Cursor save/restore
- Working history window
* Effects
- Effects broken down into three menus: Generate, Effect, and
Analyze
- Generate menu lets you generate silence, noise, or a tone
- Nyquist support (supports plug-ins written in Nyquist,
an interpreted functional language based on Lisp)
* Localization
- Improved localization support
- More languages available
- Language selection dialog on startup
* Mac OS X
- Support for more audio hardware
- Support for full-duplex (play while recording)
- Support for MP3 exporting using LameLib Carbon
* Unix
- Audacity now has a man page (it describes command-line
options and how to set the search path)
* File Formats
- Uses libsndfile 1.0, which fixes some bugs and
improves performance
* Searching for Files:
- On Windows and Mac OS, Audacity now looks for
translations in the "Languages" folder and all plug-ins
in the "Plug-ins" folder, relative to the program.
- On Unix, Audacity looks for translations in
<prefix>/share/locale and looks for everything else
in <prefix>/share/audacity and also in any paths in
the AUDACITY_PATH environment variable
New features in Audacity 1.1.0:
* Core audio processing:
- Support for 24-bit and 32-bit sample formats
- Automatic real-time resampling (using linear
interpolation)
* Effects:
- Support LADSPA plugins on Linux / Unix
* File formats:
- New XML-based Audacity project format
- Full Ogg Vorbis support now (importing and exporting)
- Export to any command-line programs on Unix
- Support for reading and writing many more types of
uncompressed audio files, including ADPCM WAV files.
* Toolbars

operating system's colors
- New toolbar buttons (Skip to Start, Skip to End)
- New Edit toolbar
- Toolbar buttons disable when they're not available
* User Interface
- Fully customizable keyboard commands
- Autoscroll while playing or recording
- New Ruler, used in main view and in
FFT Filter effect

color inside the peak values

- Audacity can now be localized to different foreign
languages.

* libmad for fast MP3 importing
* libid3tag for editing MP3 file information
* libsndfile to read and write more audio file formats
* PortAudio for cross-platform audio playing and recording
