Zinf (formerly FreeAmp ) is a free audio player for Windows and Linux . Zinf supports the formats MP3 , (Ogg) Vorbis , WAV , audio CDs and is able to play streaming audio .

It is distributed as free software under the terms of the GNU General Public License (GPL). It is written in the programming languages C and C ++ and is based on mpg123 and the GTK + user interface toolkit .


A first development version of FreeAmp was released on July 2, 1998. Initially, FreeAmp processed MPEG audio using the decoder developed by Xing Technology. Version 2.0 was released on December 18, 1999. Since the term "AMP" is a registered trademark of PlayMedia Systems, Inc. and the latter asserted its rights, the FreeAMP project had to be renamed. From version 2.2.0 from June 2002 onwards it is now published under the name "Zinf". Zinf is a recursive acronym , which stands for " Z inf I s N ot F reeA * p".

The further development seems to have stopped for some time. No new versions have been published for a long time. The last download is from the beginning of 2004, while the Windows version is even older and even contains some serious bugs related to the Ogg Vorbis format.
