The Seismic Analysis Code software is available to IRIS Members and Affiliates.
As of October 2006, IRIS may also distribute the SAC software to collaborators such as the
U.S. Geological Survey, Air Force Technical Applications Center, members of the
International Federation of Digital Seismograph Networks and other non-U.S. seismological
institutes who are involved in relevant research projects with IRIS.
However, IRIS will not distribute the SAC software to any country on the
embargoed list of the U.S. Department of Commerce.
The Seismic Analysis Code: A Primer and User’s Guide by George Helffrich, James Wookey and Ian
Bastow has just been published by Cambridge University Press.

Because of the nature of the SAC license, IRIS cannot distribute a
binary distribution for Cygwin. For a more detailed explanation, see
http://cygwin.com/licensing.html. IRIS used to provide a
separate source distribution for Cygwin, but recent releases (starting with v1.7)
can build on Cygwin with the same source distribution as the other platforms.
Cygwin users should request the source distribution and consult the file
sac-101.6/Readme.buildsac for Cygwin-related build instructions.
