Static Z Software has released Sound Siphon 1.1, an update of the tool for capturing application audio on your Mac. The new version brings application audio capture.
Sound Siphon is a software package that makes your Mac’s audio output available as an audio input device. It enables you to send audio from one application to another where it can be processed, streamed, or recorded. Using it simply involves selecting a microphone in your favorite app. Sound Siphon works with Core Audio to provide this capability to all of your audio apps.
Sound Siphon (http://staticz.com) requires Mac OS X 10.9 or higher and costs US$29.99. A demo is available for download.
