Asio | Link
Imagine you are building a generic "ASIO to ALSA" bridge on Linux (via Wine) or an "ASIO to WASAPI" wrapper on Windows. You might use asio_link to ensure that the bridge driver appears correctly in your DAW's audio settings menu.
In your DAW (e.g., Reaper or Ableton Live), select ASIO Link Pro as your Audio Device. asio link
