CDex is a free software for Digital Audio Extraction from Audio CD (a so called CD ripper) and audio format conversion for Microsoft Windows. It converts CDDA tracks from a CD to standard computer sound files, such as WAV, MP3, or Ogg Vorbis. Released under the terms of the GNU General Public License (GPL), CDex is free software. It is developed and maintained by Georgy Berdyshev. It was originally written by Albert L. Faber.


CDex is able to convert CD audio into several formats including WAV, Vorbis, MP3 (using the LAME encoder), VQF, Musepack, APE, and many others. As of version 1.70b2 FLAC encoding is native, but for version 1.51 FLAC[1] and other codecs can be used by using an external encoder. For convenience, it supports CD-Text to allow ripped tracks, with reduced user effort, to have the names of songs, artists and albums. It can also automatically identify (most) inserted audio CDs and look up the metadata by means of an online database (freedb) for automatic tagging, naming and sorting of ripped files.[2] It also includes cdparanoia for robust CD reading, but does not include AccurateRip database checking for robust rip verification. CDex is considered to be very configurable, but also relatively complicated to use.[3]


In 2000, at the start of the beta phase for version 1.30, CDex was turned into a free software project (“cdexos”: “CDex Open Source”) and hosted on[4] In January 2006, the CDex homepage requested a new project manager and developer, implying that Albert L. Faber had abandoned development of CDex. On 2006-06-05, CDex 1.70 Beta 1 was released via the website. It was the first official update to the program in almost three years, with CDex 1.70 Beta 2 following soon after on 2006-06-23. On 2009-11-18 CDex 1.70 Beta 4 was released.[5] CDex 1.70 Final was released on 2014-06-29 featuring a Unicode and Multibyte version.

On June 30, 2007, just one day after the release of the GPLv3, the license of CDex was updated.
