Pair two computers and each can use the other's default microphone and default speaker as if they were its own. No cloud, no relay, no NAT traversal — the two machines talk directly over your own network or not at all.

1. 每台电脑都可以像使用自己的设备一样使用另一台电脑的默认麦克风和默认扬声器。
2. AirPlay ，让你的电脑能够接收来自 macOS / iOS 的音频。
