Rogue Amoeba has introduced Loopback for Mac OS X is a tool for enabling audio routing between applications and audio devices on your Mac. In just a few clicks, you can pass audio directly between apps.

Loopback (http://rogueamoeba.com/loopback) is designed for anyone working with audio on the Mac, from podcasters to gamers, Internet radio hosts to regular folks chatting via Skype. It requires Mac OS X 10.9 or higher, with a free fully-functional demo version available on the Rogue Amoeba site.

While in trial mode, the quality of audio passing through Loopback’s virtual devices will be degraded after 10 minutes. Loopback is regularly-priced at $99. For a limited time, it can be purchased at a special introductory price of $75.

St. Clair Software has announced Default Folder X 5.0 (http://www.stclairsoft.com/DefaultFolderX/index.html), an upgrade to the utility for Mac OS X. Default Folder X enhances the file dialogs in all Mac OS X applications.
