Fre:ac
fre:ac is a free audio converter and CD extractor for Windows, Linux, macOS, and FreeBSD, distributed under the GPL-2.0-or-later. Besides extracting audio from compact discs (with various features including hidden track detection), 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 Ogg Vorbis, FLAC, MP3, MP4/M4A, AAC, WAV, WMA, and more. 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. The user interface is multilingual with 43 languages and is able to be a portable install on a USB drive. History. 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. After several "0.x" versions, 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 project changed its name to fre:ac with the release of version 1.0.17 on November 14, 2010. On March 29, 2020 the project released fre:ac 1.1 as a major update adding native support for Linux, macOS and FreeBSD. The 1.1 update also introduced support for multithreaded file conversions, DSP processing, multichannel audio and an integrated tag editor and removed support for the Bonk format after which the program was named  until 2010. The latest update, version 1.1.5, was released on Sunday, June 27, 2021. Starting from that version, fre:ac has AccurateRip support.
