Danger Cove Porthole 1.7.1 Multilingual MacOSX | 5 MB
Porthole's main goals are to be elegant and make AirPlaying Spotify and other music services as easy as it should be.
AirPlay + Your Mac's Speakers
Play through your Mac's output while you're streaming. All the wireless receivers and your Mac will even play in sync!
Adjust the Volume per Speaker
Use the volume keys on your keyboard to alter the main AirPlay volume. Even the mute button just works.
Think some of your speakers are a little too loud or too soft? Adjust their output by going into Preferences → Volume.
Save Clicks With the Speaker Panel
Start or stop streaming without taking your mind off what you're doing by toggling speakers with the press of a button.
Use Porthole's hotkey activated Speaker Panel to manage your setup, sans mouse.
