SonATA
From setiquest wiki
SonATA is an acronym for "SETI on the ATA." It is a signal processing software system that controls the operation of the ATA, collects data, and performs signal analysis.[1] SonATA does real-time SETI analysis and it replaces the older, hardware-based Prelude system that was previously used. SonATA uses UDP multicast packets as a data bus for moving sampled data into, throughout, and out of the system.

Development
Originally SonATA was developed at the SETI Institute using a closed source development model. The SonATA software was written by a large number of people over the past decade. Then Jill's TED wish created setiQuest which utilized an open model.
The open source SonATA code was officially released on March 1st 2011. It uses the GPLv3 license[2] and it is available for download on GitHub.[3]
Documentation
Read the SonATA system documentation to learn how it works:

Languages
SonATA uses a variety of programming languages. This is how GitHub sums up the SonATA code:[4]
- C
- C++
- Fortran
- Java
- JavaScript
- Matlab
- Objective-C
- Python
- shell script
- Tcl/Tk
- x86 assembly
Note: We suspect the GitHub code summary is not quite correct. For example there is no "R" code in SonATA.
Another code perspective comes from running the program cloc[5]. This report was generated by cloc analyzing the SonATA code cloned from GitHub on March 21, 2011:
