Para citar RJ Jacquez , um evangelista sênior de produtos da Adobe:
One of the most powerful new features in RoboHelp 8, which rarely gets mentioned, is the new Scripting engine, which Incidentally is the same scripting language also used in Photoshop, Illustrator, Bridge, Soundbooth and other CS4 products.
Put simply, the RoboHelp Scripting Language is a Javascript-based scripting language that exposes APIs to invoke most of the basic functionality of RoboHelp in an effort to automate complex or repetitive tasks.
For developing new scripts, all of our Adobe applications with scripting support use Adobe ExtendScript Toolkit CS4, which naturally ships with Adobe RoboHelp 8.

Parece que o SoundBooth usa o ExtendScript. O link na citação aponta para o centro de scripts da Adobe, onde você pode fazer o download do ExtendScript Toolkit e de alguns PDFs para começar a usar scripts.
