As of version 1.0, released June 20th 2022, FarPlay supports
multi-user sessions and built-in video.
Note for Windows:
Starting with version 0.3.7, FarPlay supports native Windows audio devices, so you can use FarPlay immediately with your computer's integrated audio device, without any additional downloads. FarPlay also supports ASIO devices and drivers, which will give you the best possible latency.
Note for Linux:
Starting with version 0.3.7, FarPlay includes experimental support for Jack and PulseAudio. That means you'll need pulse and jack libraries installed in your system to run FarPlay. For the best latency, use ALSA or Jack. Jack should be configured to run at 48kHz to work with FarPlay. Also, the buffer size in preferences is ignored when Jack is used; FarPlay will use jackd's Frames/Period value instead. PulseAudio generally has higher latency than JACK or ALSA, but might be good for Broadcast Output or less latency-critical scenarios.
