SAC (Seismic Analysis Code) is a general
purpose interactive program designed for the study of sequential
signals, especially time series data. Emphasis has been placed on
analysis tools used by research seismologists in the detailed study
of seismic events. Analysis capabilities include general arithmetic
operations, Fourier transforms, three spectral estimation techniques,
IIR and FIR filtering, signal stacking, decimation, interpolation,
correlation, and seismic phase picking. SAC also contains an extensive
graphics capability.
For further background information, see SAC
Availability for the IRIS Community, by Peter Goldstein and Arthur
Snoke (Feature Article - IRIS DMS Newsletter, March 2005). History
has a summary of major modifications made to SAC since 1990. Changes
includes details about modifications made since 2005.

SAC Software Availability
The SAC Software is available free through IRIS to IRIS Members and Affiliates.
In addition, 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 (subject to export control) who are involved
in relevant research projects with IRIS.
The current version of SAC is Version 101.5c (February 2012),
and is available in compressed tar format either as a source distribution
or as a pre-built binary distribution for selected platforms and operating
system.
