1. Installation and Usage (version 2 and 3) - Andersama/obs-asio GitHub Wiki

  • Check the Releases section here.
  • Download and install the latest installer.
  • WARNING: it is a common misconception that this plugin should allow capture of an asio device outputs. It only allows capture of INPUTS which is as it should be. One can capture a mike, but not what goes to the speakers (the 'What U Hear' capture of SoundBlaster devices is NOT possible as a rule, though some asio devices may have that capability). The asio sdk does not allow it. So the mix prepared in a DAW will NOT be able to be captured by this plugin in general. There are workarounds though. Check the Wiki section Capturing Mixes
  • The binaries were built using the Juce library along with our open source openasio sdk, which implements the asio sdk in compliance with GPL v3.
  • This version of the plugin has similar capabilities as the one based on bassasio (which can not be released); if this version of the plugin does not work, you could give a shot to the bassasio version though you'll have to compile it yourself. Check the Build Instructions in this wiki.

Screenshots and How to use

  • Add an Asio source in OBS Studio Source Panel. source
  • In the Source Properties window, select the input channels of your asio device (Rearoute in the next screenshot). Properties and driver panel
    • OBS Channel 1 is the first audio output channel, etc. For stereo there are obviously two output channels. For surround sound output, there will be more: ex for 7.1 surround there will be 8 entries from OBS channel 1 to OBS Channel 8.
    • The drop downs for OBS Channels 1-8 allow routing from input channels of the asio device to output channels of obs-studio.
  • If you click on Control Panel, the asio driver panel is fired so that you can review your device settings (sample rate, buffer size). (In the screenshot above, it's the ReaRoute Configuration window).
