Airfoil Speakers

Airfoil Speakers is an audio streaming and speaker management utility from Rogue Amoeba that lets you send audio from your Mac to AirPlay-compatible speakers, headphones, and other devices around your home or network. It works by intercepting audio from any application—music players, web browsers, podcasts, games—and routing it wirelessly to remote speakers without needing native AirPlay support from each app. Power users and audio enthusiasts rely on it to centralise audio playback across multiple rooms, connect legacy audio devices via AirPlay, and manage speaker zones from the menu bar. It serves as both a sender (pushing Mac audio out) and a receiver (capturing audio from other devices).
