  The Long Wavelength Array Software Library (LSL) is a Python module that
provides a collection of utilities to analyze and export data collected at the
first station of the Long Wavelength Array, LWA1. Due to the nature of the data
format and large-N ($\gtrsim$100 inputs) challenges faced by the LWA, currently
available software packages are not suited to process the data. Using tools
provided by LSL, observers can read in the raw LWA1 data, synthesize a filter
bank, and apply incoherent de-dispersion to the data. The extensible nature of
LSL also makes it an ideal tool for building data analysis pipelines and
applying the methods to other low frequency arrays.
