fre:ac (formerly BonkEnc) is a free audio converter and CD extractor for Microsoft Windows, Linux, OS X and FreeBSD, distributed under the GNU General Public License.[1] The project is active with periodic releases.

Besides extracting audio from compact discs (with various features including HTOA), fre:ac can also convert audio files from one format to another or to the same format but a lower bitrate. fre:ac is compatible with many audio formats such as MP3, MP4/M4A, Ogg/Vorbis, FLAC, AAC, WAV, WMA and more.[2][3] fre:ac uses the CDex library to convert from CDs and uses freedb to retrieve artist/song information from the internet which is written to the files as various types of ID3 tags; this library supports cdparanoia which aims to improve audio quality.[4] The user interface is multilingual with 38 languages and is able to be a portable install on a USB drive.


The first public version of fre:ac was published in 2001 under the name BonkEnc. The program was originally developed to convert audio to the proprietary lossy/lossless Bonk format, as well as MP3. Over time MP3 became dominant, although fre:ac still supports Bonk. After several versions of "0.x", with added support for other formats and extracting audio from compact discs, version "1.0 Beta 1" was released on July 5, 2003 which officially marked the beginning of the beta phase.

Finally, on February 21, 2007 the first stable version of the program version "1.0" was released. The latest update 1.0.25 was released on September 11, 2015.
