Summary
- Krisp Microphone and Krisp Speaker: virtual devices
- Two virtual devices on the same audio stream: risk of conflicts and double processing
- Possible results: feedback, echo, or other audio artifacts
- In the Krisp app, select a physical microphone and speaker.
How do virtual devices work in general?
Virtual devices are software emulations of hardware. They "pretend" to be hardware to the system and other software. When you try to use two virtual devices together, it can cause conflicts because neither has the underlying physical infrastructure to manage and process the data in the same way actual hardware does.
Moreover, virtual devices often intercept and modify data in some way. If two virtual devices try to modify the same data stream simultaneously, this can cause unexpected behavior or errors, as the data might get processed twice or in unpredictable ways.
Virtual devices and Krisp
Krisp Microphone and Krisp Speaker are virtual devices. When you use one of them together with another virtual device, the audio can be modified by both, leading to feedback, echoing, or other audio artifacts.
