It looks like you’re asking for a helpful write-up on ReaStream — a plugin from the ReaPlugs suite by Cockos (the makers of REAPER). Below is a clear, practical overview of what ReaStream does, how to use it, and why it’s useful.
What is ReaStream? ReaStream is a network audio plugin. It sends or receives audio over a local network (LAN or even over the internet with proper setup) between two or more instances of the plugin running on different computers. It can be used as an effect (FX) or an instrument in any DAW that supports VST, AU, or AAX plugins, not just REAPER. Key capabilities:
Send audio from one computer to another with very low latency. Stream multiple channels (up to 64). Work in send or receive mode. Support for unicast (one sender → one receiver) or multicast (one sender → many receivers). Work across Windows, macOS, and Linux.
Common Use Cases | Use case | How it helps | |----------|----------------| | Two DAWs on separate computers | Send a track from DAW A to DAW B without physical cables. | | Main + backup computer | Route audio to a secondary machine for recording or processing. | | Rehearsal/recording with multiple musicians | Each person can have a headphone mix from a central computer. | | Live sound & remote mixing | Send splits to a broadcast or streaming PC. | | Video editing + audio processing | Send audio from a video editor to a DAW for advanced mastering. | reastream

Channels : 1–64. Multicast (optional): Check if multiple receivers. Leave Remote port same as Local if using unicast.
On the Receiving computer:
Insert ReaStream on a new track. Set Mode → Receive audio/midi . Local port → same as sender’s local port ( 9999 ). Remote address → sender’s IP address. Channels match sender’s count. Arm track monitoring → you should hear audio. ReaStream is a network audio plugin
✅ Tip: Use wired Ethernet for best latency/stability. Wi-Fi can work but is less reliable for multichannel.
