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 High-quality audio resampling. 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. SoundTouch: LGPL Changes tempo without changing pitch and vice versa.

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 audacity-help@lists.sourceforge.net 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.

Changes in 1.2.5: * An official Intel Mac version is now available. * Fixed bug in Generate Silence which caused it to apply to all tracks instead of just the selected ones. * Mac OS X: audio device opening code has been rewritten. First, it is much more conservative about changing d...
