REAC Audio Source 0.3.2

Introduction

This plugin provides audio source(s) from REAC, which is a proprietary audio-over-ethernet protocol developed by Roland. The protocol provides 24-bit 40-channel uncompressed audio.

Hardware connection

This plugin was developed and tested with Roland M-200i (ja) as the connection drawn in a figure below.

In the computer running OBS Studio, it is recommended to have a dedicated ethernet device to connect to REAC network.

Limitation

• Not all binaries are tested.
  • MacOS: Version 0.1.2 was briefly tested. However, amount of testing is not so large because I don't mainly use macOS.
  • Ubuntu: A deb package is provided but never tested. The source code is tested on CentOS 8 and CentOS Stream 9.
  • Windows: Windows: Tested (version 0.3.0 on VirtualBox)
• Only 48 kHz sampling frequency is supported since the sampling frequency is hard-coded to 48 kHz in the plugin. To use this plugin, you have to set the sampling frequency of the REAC device to 48 kHz. (Still you can set any sampling frequency on OBS Studio and libobs will automatically convert it.)
