Spike Software (http://www.spikesoft.net) has launched Audio Switcher 2.0.3, a Mac OS X utility that allows you to switch your audio input and output between different audio devices.
Automatically detecting when your audio devices are connected or disconnected, the tool resides in the Status Bar. Version 2.0.3 introduces a re-configured preferences management system, improved auto-launch support and a few bug fixes.
Audio Switcher requires OS X 10.7 or later and costs US$4.99. It’s available at the Mac App Store in the Utilities category. Current users can receive the free 2.0.3 update via the Mac Store.
