foobar2000[a] (often abbreviated as fb2k or f2k) is a freewareaudio player for Microsoft Windows, iOS, Android, macOS, and formerly Windows Phone, developed by Peter Pawłowski. It has a modular design, which provides user flexibility in configuration and customization.[4] Standard "skin" elements can be individually augmented or replaced with different dials and buttons, as well as visualizers such as waveform, oscilloscope, spectrum, spectrogram (waterfall), peak and smoothed VU meters, which all of them are analysis-oriented, at least for built-in visualizations. foobar2000 offers third-partyuser interface modifications through a software development kit (SDK).
foobar2000 was first released on 20 December 2002 and developed by Peter Pawłowski, who had previously worked at Nullsoft and developed plugins for Winamp. He created foobar2000 with the audiophile community in mind.[5] The software's mascot and logo icon consists of a white "alien cat".
foobar2000 supports Windows, though the support of older versions for Windows XP and Vista has been dropped as of version 1.6 (released 2020).[6][7]Windows 2000 support was dropped as of version 0.9.5 (released 2008) and Windows 95/98/ME/NT4 support was dropped as of version 0.9 (released 2006).[8]
Most functionality also works as intended under Wine on Linux, although the program's crash reporter will detect Wine and direct the user to the Wine Bugzilla.[9] The vast majority of plugins and themes work fine, however, certain plugins may cause issues. Safe mode allows users to disable all plugins temporarily to debug the issue.
foobar2000 versions since 0.9.5 feature a revamped default interface, with embedded support for album list, album art,[10]spectrum visualization, and some other features and improvements.
In May 2016, versions for mobile devices were released,[11][12][13][14] and in January 2018, an early beta version for macOS was released.[15] In April 2023, version 2.0 was released out of beta with native support for 64-bit, dark mode, and ARM.[16]
foobar2000 also has a highly customizable user interface, advanced tagging capabilities and support for rippingAudio CDs, as well as transcoding of all supported audio formats using the Converter component. The player can read inside ZIP, GZIP, and RARarchives.
Users can configure the foobar2000 Media Library with automated folder watching[20] and Windows Media streaming.[21] The client is built with an open component architecture, allowing third-party developers to extend functionality of the player.[22]
Other optional features include playback statistics, CD burning, kernel streaming, ASIO support, WASAPI output compatibility, and a UPnP/DLNA renderer, media server and controller for networking. Third-party support is also present in the audio client. For instance, foobar2000 supports Last.fm scrobbling and integration with Apple iPod, including album art support and automatic transcoding of audio formats not supported by iPod itself.

foobar2000 developer Peter Pawłowski has also made other audio software, including Boom, which his web site describes as an "easy to use audio player intended for casual computer users". It runs on Windows.[23]
