PolySound

PolySound lets you play audio through multiple output devices simultaneously on macOS — speakers, headphones, AirPods, HDMI, USB DACs, all at the same time.

Living in your menu bar, PolySound makes multi-device output effortless. Select any combination of connected outputs and PolySound automatically creates a multi-output device and switches your system to use it. Per-device volume controls, automatic reconnection when devices come back online, and zero configuration.

FEATURES
• Play audio on any combination of connected output devices at once
• Per-device volume control
• Automatic rebuild when devices connect or disconnect
• Lightweight menu bar app — no dock clutter
• Launch at login (optional)
• 100% offline — no tracking, no analytics, no network requests

PRIVACY
PolySound does not collect any data. The app runs entirely on your device with no telemetry, advertising, or third-party services.

Supports macOS Sonoma 14.6 and later, including Sequoia and Tahoe.
