What is ASIO ?

Audio Stream Input/Output (ASIO) is a computer sound card driver protocol for digital audio specified by Steinberg, providing a low-latency and high fidelity interface between a software application and a computer's sound card. Whereas Microsoft's DirectSound is commonly used as an intermediary signal path for non-professional users, ASIO allows musicians and sound engineers to access external hardware directly. (From ASIO Wikipedia article ).

This plugin

  • We developed a plugin for OBS Studio which is a leading open-source streaming and compositing software.
  • It allows capture of ASIO sound devices, which are often professional or semi-professional grade hardware for studio or home-studio use. * The plugin is designed for Windows and has been tested on windows 10 x64.
  • There are five versions but only two are released. They can be found on branches asio-juce, asiobass, asioportaudio, asioportaudio_v2, asiort of this repo.
    • They use different audio API to host asio drivers (namely JUCE, Bassasio, Portaudio and RtAudio).
    • The JUCE and Bassasio plugin have the most functionalities; they allow multi-device as well as multi-client operation.
    • The 2 Portaudio plugins have multi-client but not multi-device capability.
    • The portaudio plugin v2 differs from portaudio plugin v1 in allowing sources with different devices although only one device is active.
    • The RtAudio based plugin is the most basic one and is not released.
  • Multi-device capability means several asio devices can be used at the same time with OBS Studio. Most applications written with ASIO support including DAW's are limited to one device.
  • Multi-client capability means OBS can create several asio sources with different channel selections from the same device.
