The free ''libgsm'' codec can encode and decode GSM Full Rate audio.<ref>[http://www.quut.com/gsm/ The GSM 06.10 lossy speech compression library and its applications], Retrieved 2009-08-31</ref><ref>Ubuntu.com [http://packages.ubuntu.com/libgsm1 Shared libraries for GSM speech compressor], Retrieved 2009-08-31</ref> "libgsm" was developed 1992–1994 by [[Jutta Degener]] and Carsten Bormann, then at [[Technische Universität Berlin]].<ref>[http://www.quut.com/gsm/gsm-1.0.13.tar.gz libgsm - README - GSM 06.10 13&nbsp;kbit/s RPE/LTP speech compression], Retrieved 2009-09-20</ref> Since a GSM speech frame is 32.5 bytes, this implementation also defined a 33-byte nibble-padded representation of a GSM frame (which, at a frame rate of 50/s, is the basis for the incorrect claim that the GSM bit rate is 13.2&nbsp;kbit/s). This codec can also be compiled into [[Wine (software)|Wine]] to provide GSM audio support.

There is also a [[Winamp]] plugin for raw GSM 06.10 based on the libgsm.<ref>Cedric Hans [http://www.mlkj.net/gsm/ Plug-in Winamp for raw GSM 06.10], Retrieved 2009-10-09</ref><ref>Cedric Hans (2004-06-08) [http://www.winamp.com/plugins/details/142107 Winamp Plug-in - Raw GSM Winamp Plugin] {{webarchive|url=https://web.archive.org/web/20090908233955/http://www.winamp.com/plugins/details/142107 |date=2009-09-08 }}, Winamp, Retrieved 2009-10-09</ref>

The GSM 06.10 is also used in [[VoIP]] software, for example in [[Ekiga]], [[QuteCom]], [[Linphone]], [[Asterisk (PBX)]], [[Ventrilo]] and others.
