CastAway's settings are minimal — just two fields. Click the Settings button in the Six Pack area to open the settings dialog.
| Setting | Description |
|---|---|
| Station IP Address | The IP address of the computer running AutoCast. Your station engineer provides this. Example: 74.125.200.100. For local network testing, use the Mac's LAN IP (e.g., 192.168.0.121). |
| PIN | A short authentication code set by the station operator in AutoCast's autocast.json settings file. Default: 1234. |
Settings are saved in your browser's local storage. When you return to CastAway, the IP and PIN are already filled in — you just click Connect.
To change your settings, click Settings again, update the fields, and click Connect. The new values replace the old ones.
If you use multiple devices (laptop and tablet), each device saves its own settings independently. You'll need to enter the IP and PIN once on each device.
The PIN is set at the station in AutoCast's settings file (autocast.json). Look for the castAwayPIN key. Only the station operator or engineer can change this — it's not changeable from CastAway.
If the PIN changes, everyone using CastAway will need to update their settings.
The Settings dialog includes a Microphone Level section for dialing in your mic before you go live.
| Control | Description |
|---|---|
| Gain Slider | Adjusts your microphone gain from 0% (silent) to 500% (maximum boost). The default is 100% — normal, unmodified level. Drag it higher if your mic is quiet, or lower if you're too hot. |
| VU Preview Meter | A live level meter that shows your mic input in real time. Use this to check your levels before going live — no one hears you until you click Go Live. |
Your gain setting is applied on top of the browser's built-in audio processing (echo cancellation, noise suppression, and auto gain control) using the Web Audio API. Think of it as a final trim knob after the browser has already cleaned up the signal.
Open Settings, talk into your mic, and watch the VU meter. Adjust the slider until your voice peaks into the amber zone without hitting purple. That's your sweet spot. Do this before every remote — different rooms sound different.
At the bottom of the Settings dialog is a Diagnostic Mode checkbox. When enabled, CastAway displays detailed connection and audio messages in the MessagePad — things like WebSocket handshakes, WebRTC negotiation steps, and audio stream status.
You won't need this during a normal broadcast. But if something isn't working and your station engineer asks you to "turn on diagnostics," this is where you do it. The extra messages can help pinpoint exactly where a connection is getting stuck.
