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:

  wxWidgets: 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.

  libflac: BSD-like license.
    Optional separate download for libsndfile

  libresample: LGPL

Compilation instructions:

First you must download wxWidgets 2.4.x from:

  http://www.wxWidgets.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 please email
[e-mail] or see the audacity forum
http://www.audacityteam.org/forum/

Known issues/problems:

  * Audacity can import and display MIDI files, but they cannot be played
    or edited.

  * On Pentium-II based systems effects using the Soundtouch libraries may
    cause Audacity to crash. This is a problem with the upstream library.

  * Windows only: If you installed one of the 1.1.x beta versions,
    you must uninstall it before installing Audacity 1.2.
    (You do not need to uninstall earlier 1.2 or 1.0 releases.)

  * Linux only: Recording in full duplex on some Linux systems causes
    mono recordings to sound slowed-down or low-pitched.  To work around
    this problem (a bug in the ALSA OSS emulation code), set Audacity to
    record in stereo.

  * Mac OS X only: Audacity cannot work with files or folders that
    are contained inside folders with international characters
    (accent marks, etc.) in their names.  Note that files with
    accented characters work, and Audacity projects with
    accented characters work.  Only files inside of folders
    with accented characters in their names will cause problems.

  * MacOS X only: Some users find that after running Audacity other media
    players don't produce any sound or crash. Audacity tries to select the best
    quality settings your system is capable of, to give the best recordings
    possible. Some sound drivers also retain these settings as defaults for
    other applications, which can cause these symptoms
 
    To get round this, enable the option "Do not modify audio device settings"
    on the Audio I/O tab of the preferences, and make sure that your sound
    device is set up (in the Apple Sound and Midi Setup utility) to work in
    stereo, 16bits, with a sample rate of 44100Hz or 48000Hz.  See also
