fre:ac is a free audio converter and CD ripper with support for various popular formats and encoders. It currently converts between MP3, MP4/M4A, WMA, Ogg Vorbis, FLAC, AAC, WAV and Bonk formats.

With fre:ac you easily rip your audio CDs to MP3 or WMA files for use with your hardware player or convert files that do not play with other audio software. You can even convert whole music libraries retaining the folder and filename structure.

The integrated CD ripper supports the CDDB/freedb online CD database. It will automatically query song information and write it to ID3v2 or other title information tags.

Hotfix for fre:ac on macOS 10.15 Catalina Print E-mail
Sunday, 13 October 2019 21:47

The fre:ac v1.1 Alpha 20190423a hotfix has been released to add support for macOS 10.15 Catalina.

In previous releases up to 20190423 it's not possible to select any files or folders in file open/save dialogs. It looks like this is caused by a broken open/save panel programming interface in macOS Catalina. Chances are that this will be fixed in a future macOS update. In the meantime, the 20190423a hotfix implements a work-around for this incompatibility.

The update is available in the downloads section.
