fre:ac is a free audio converter and CD extractor for Windows, Linux, macOS, and FreeBSD, distributed under the GPL-2.0-or-later.

[2] 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 at a lower bitrate (a higher bitrate can be forced but this does not increase the quality of the output, instead resulting in an overall loss).

fre:ac is compatible with many audio formats such as Ogg Vorbis, FLAC, MP3, MP4/M4A, AAC, WAV, WMA, and more.

On March 29, 2020 the project released fre:ac 1.1 as a major update adding native support for Linux, macOS and FreeBSD.

[9] The latest update, version 1.1.7, was released on Monday, March 6, 2023. fre:ac won the SourceForge Community Choice Project of the Month award in October 2015.
