Signal Shifter is a tiny application that lives in the Menu Bar.

The application creates a complete list of your input audio devices, output audio devices and Bluetooth devices that can be used as audio input or output. This way, you have all your audio sources in a single place.

You can easily toggle between default devices and enable or disable Bluetooth devices.

You can have Signal Shifter run automatically when you login. Simply use the application’s Settings.

Additionally, you can set up low battery notifications for your Bluetooth devices.

If you have any problems, please familiarize yourself with the list of known Issues or create a new one.
