AudioSwitcher is a menu bar that lets you quickly switch between all input and output devices available. In addition, you can change the volume of any device without having to change your input / output current. You can quickly change the sampling frequency or output to multiple devices simultaneously.
Using the preference screen may choose to ignore certain devices, configure an input or output device default start and volume.
AudioSwitcher supports any device available for the system: AirPlay, USB, HDMI, Thunderbolt, Bluetooth, etc.
AudioSwitcher is ideal if you have multiple devices connected to your Mac sound and want to switch between them without having to use System Preferences.
It is ideal for a home theater setup that allows selection of default devices (and volumes) at startup, and also allows you to quickly route the output to AirPlay devices with a single click.
