GstLAL provides a suite of GStreamer elements that expose gravitational-wave data analysis tools from the LALSuite library for use in GStreamer signal-processing pipelines.

Examples include an element to add simulated gravitational waves to an h(t) stream, and a source element to provide the contents of .gwf frame files to a GStreamer pipeline. Overview

The GstLAL software package is used for the following activities:

  • GstLAL: Provides core Gstreamer plugins for signal processing workflows with LIGO data and core python bindings for constructing such workflows.
  • GstLAL Inspiral: Provides additional signal processing plugins that are specific for LIGO / Virgo searches for compact binaries as well as a substantial amount of python code for post-processing raw signal processing results into gravitational wave candidate lists. Several publications about the methodology and workflow exist, see publications
  • GstLAL Ugly: An incubator project for gradual inclusion in the other packages.
