| ---------------- | ------------------------------------------------------------------- |
| Operating system | Windows 11                                                          |
| OBS Studio       | 64-bit OBS Studio 30 or 31                                          |
| Installation     | One separate 64-bit installer per vAudioLink product                |
| Permissions      | Ability to install an OBS plugin and restart OBS                    |
| Audio            | A working OBS audio source and headphones                           |
| Network          | Outbound internet access to the vAudioLink panel and selected relay |

<Warning>
  Close OBS before installing or updating a vAudioLink product. An open OBS process can keep the old plugin DLL loaded.
</Warning>

## Account requirements

<Tabs>
  <Tab title="Host or sender">
    A hosted session requires a vAudioLink account with the appropriate hosted-relay entitlement. Sign-in happens through a browser authorization flow started from the OBS dock.
  </Tab>

  <Tab title="Guest or receiver">
    No account is required. You need the matching product installer and the complete temporary credential from the host.
  </Tab>

  <Tab title="Self-host user">
    No vAudioLink account is required. Start the bundled relay or server from the product's **Self-host** tab. If your partner is outside your network, follow the dock's Windows Firewall and router guidance.
  </Tab>
</Tabs>

## Product-specific preparation

<AccordionGroup>
  <Accordion title="ASMR Collab">
    Prepare a stereo OBS audio source. For binaural microphones, verify left and right orientation locally before involving the guest.
  </Accordion>

  <Accordion title="Music Collab">
    Prepare the vocalist's microphone as an OBS source. The host should also have either a supported YouTube URL or a local `.opus` or `.ogg` backing file.
  </Accordion>

  <Accordion title="Scene Share">
    Prepare the complete OBS Program view you intend to send. Scene Share sends the whole program, not an individual scene item.
  </Accordion>
</AccordionGroup>

## Recommended session equipment

* Closed-back headphones for both participants.
* A wired network connection where practical.
* A separate private channel for sharing the guest key.
* Enough time for a local test recording before the live session.
* A fallback communication channel if the production connection needs to be restarted.

## Network and security check

* Allow OBS and the installed vAudioLink plugin through endpoint security software.
* Do not publish guest keys, receiver URLs, access tokens, or OBS logs containing secrets.
* Verify both Windows clocks are set automatically.
* If a corporate or school network blocks the connection, test on another trusted network before changing firewall policy.
