Adobe has put out three free public betas: Dreamweaver, Fireworks and Soundbooth, all of which will be part of the next-generation Creative Suite when it arrives. Its delivery date is still a big secret.

The betas are only good for 48 hours once they’re downloaded unless you’re a Creative Suite 3 customer.

Dreamweaver is for web design and development, Fireworks for prototyping and Soundbooth for audio creating and editing.

Adobe describes the early release software as “a taste of the radical workflow enhancements that we have in store as we redefine how designers and developers collaborate to deliver stand-out digital experiences.”

The Dreamweaver beta includes a new Related Files Toolbar that displays HTML files, links to JavaScript documents and integrated XML data in complex pages. And Code Navigator can make changes to code that appears in various parts of a document with just one update.

A new Live View Mode, based on the open source rendering engine Webkit, lets users see content in real-world, real-time environments without having to leave Dreamweaver for a browser. Adobe says this feature gives users the ability to freeze JavaScript language to debug interactive pages as well as view and interact with Flash content.

The Fireworks beta includes a new user interface that is now consistent with other applications in the Creative Suite, The beta is also compatible with Adobe AIR, HTML, Adobe Flash and Adobe Flex Builder so users can create a design once and deploy to whichever application platform is required.

The Dreamweaver and Fireworks betas run on multiple operating systems, including XP with Service Pack 2, Vista and Mac OS X 10.4.11 or later on PowerPC G5 or Intel-based systems. The Soundbooth beta won’t run on PowerPC-based Macs.
