Hello,
For my thesis I’m developing a prototype using Unity and FMOD Studio and I would like to use an external microphone connected to my audio interface (Focusrite 6i6) to pass the environmental sound to the user’s headphones in Unity. I do not need to record just need to deliver the sound from the microphone.

You can use the Core API function [System::setOutput](https://www.fmod.com/resources/documentation-api?version=2.1&page=core-api-system.html#system_setoutput) to choose the interface, ensuring the correct driver set with [System::setDriver](https://www.fmod.com/resources/documentation-api?version=2.1&page=core-api-system.html#system_setdriver). From there you can see the microphone recording example provided with the API examples (included in your API installation). You can modify this to provide a stream of audio rather than a recording.
