libsndfile is a widely used²³ C library written by Erik de Castro Lopo for reading and writing audio files.⁴ It supports a wide variety of audio file formats and will convert automatically from one to another.⁴ It allows the programmer to ignore many details, such as endianness.

In addition to the library itself, the package provides command-line programs for converting one format to another (sndfile-convert), for playing audio files (sndfile-play), and for obtaining information about the contents of an audio file (sndfile-info).

libsndfile is available for AmigaOS, Unix-like systems, including Linux and Mac OS X, and for Microsoft Windows.⁴ It is licensed under LGPL-2.1-or-later.⁴

libsndfile is used, for example, by audio-editing software such as Audacity and Adobe Audition³ and the MP3 encoder LAME.⁵
