libsndfile is available for [AmigaOS](/source/AmigaOS), [Unix-like](/source/Unix-like) systems, including [Linux](/source/Linux) and [Mac OS X](/source/Mac_OS_X), and for [Microsoft Windows](/source/Microsoft_Windows).<ref name="site-top"/> It is licensed under [LGPL-2.1-or-later](/source/GNU_Lesser_General_Public_License).<ref name="site-top" />

libsndfile is used, for example, by audio-editing software such as [Audacity](/source/Audacity_(audio_editor)) and [Adobe Audition](/source/Adobe_Audition)<ref name=adobe/> and the [MP3](/source/MP3) encoder [LAME](/source/LAME).<ref>[https://lame.cvs.sourceforge.net/viewvc/lame/lame/doc/html/history.html LAME changelog]</ref>
