Forensic Audio Sleuth™ tool suite for the Macintosh

 
The Forensic Audio Sleuth tool suite is composed of 3 main applications and a number of smaller support apps. They were designed for use by Anthony Pellicano of Forensic Audio Labs who uses them on legal forensic-audio cases. He has used them in such public cases as the Menedez Brothers trial and the Michael Jackson afair. All of the applications are written in C with a little assembly and in total comprise about 500,000 lines of code. More details can be found in my resumé.
