Static Z Software (http://staticz.com) has announced Sound Siphon 2.0.2, an update to their audio capture application for Mac OS X.
The $39 app makes your Mac’s audio output available as an audio input device. Version 2.0.2 sports a public API (application programming interface) for third party developers, enabling them to access Sound Siphon’s application audio capture abilities. Now a developer can add the ability to record application audio to their own Mac app. A demo is available for download.
