foobar2000[lower-alpha 1] is a freeware audio player for Microsoft Windows, iOS and Android developed by Peter Pawłowski. It is known for its highly modular design, breadth of features, and extensive user flexibility in configuration. For example, the user-interface is completely customizable.[5] Its extensive software development kit (SDK) allows third-party developers enough power to completely replace the interface.

foobar2000 supports a large number of audio file formats, has many features for organising metadata, files, and folders, and has a converter interface for use with command line encoders. To maximize audio fidelity in cases where resampling or downscaling in bit depth is required, it provides noise shaping and dithering. There are a number of official and third-party components which add many additional features. The core is closed source, whereas the SDK is licensed under the Three-Clause BSD license. Since version 0.9.5, foobar2000 supports Windows XP SP2/SP3 and later releases only. This version features a revamped default interface, with embedded support for album list, album art,[6] spectrum visualization, and some other features and improvements. In May 2016, versions for mobile devices were released,[7][8][9][10] and in January 2018, an early beta version for macOS was released.[11]



At its core, foobar2000 natively supports a range of audio formats, including MP1, MP2, MP3, MPC, AAC, WMA, Ogg Vorbis, FLAC / Ogg FLAC, ALAC, WavPack, WAV, AIFF, AU, SND, CD, Speex, and Opus.

foobar2000 also has a customizable user interface, advanced tagging capabilities and support for ripping Audio CDs, as well as transcoding of all supported audio formats using the Converter component. The player can read inside ZIP, GZIP, and RAR archives. Core functionality has also been tested to work under Wine on Linux.[12]

Additional features include ReplayGain support (for both playback and calculation),[13][14] gapless playback,[15] keyboard shortcuts and support for DSP effects such as equalization and crossfade.

Users can configure the foobar2000 Media Library with automated folder watching[16] and Windows Media streaming.[17] The client is built with an open component architecture, allowing third-party developers to extend functionality of the player.[18]


foobar2000 can read the APE, HDCD, AC3, DTS, SACD and DVD-Audio formats.

Other optional features include playback statistics, CD burning, kernel streaming, ASIO support and WASAPI output compatibility. Third-party support is also present in the audio client. For instance, foobar2000 supports scrobbling and integration with Apple iPod, including album art support and automatic transcoding of audio formats not supported by iPod itself.
