Audio Hub
Pick a radio location, choose a tone or pre-recorded message, then connect, receive, and transmit — all from one panel.
The Audio Hub is the command-side panel for managing incident audio. It opens from the Audio Hub button in the command tools menu. From here you choose a local or remote radio location, optionally pick a tone or a pre-recorded message, and control the audio session with Connect, Receive, and Transmit. Your selections are remembered between sessions.

Overview
The panel is four lists and a row of controls. The lists are what you are connecting to and what you are sending; the controls are the session itself.
The four lists
| List | Options | Notes |
|---|---|---|
| Local Locations | Top Radio, Middle Radio, Lower Radio | The three radio positions in the vehicle or command post. Always these three. |
| Remote Locations | Command 30, Command 31, Command 32, Command 33 | The four remote command channels. Always these four. |
| Tones | Whatever tones your agency has configured | Empty if your agency has set none up. |
| Messages | Whatever pre-recorded messages your agency has configured | Empty if your agency has set none up. |
Session controls
| Control | Description | Appearance when active |
|---|---|---|
| Connect | Opens the audio connection to the selected location. | The label changes to CONNECTED. |
| Receive | Turns receive mode on so you hear the location. | The button turns orange. |
| Transmit | Turns transmit mode on so you are heard on the location. | The button turns red. |
| Send | Sends the selected tone or message. | — |
| Close | Closes the panel. | — |
Current selection
Above the controls, the panel shows what you currently have chosen:
| Readout | Shows |
|---|---|
| Location | The single location you have selected. Hidden when nothing is selected. |
| Tone | The tone you have selected. Hidden when nothing is selected. |
| Message | The message you have selected. Hidden when nothing is selected. |
How Selection Works
| Rule | Detail |
|---|---|
| One location at a time | Local and remote locations share a single selection. Choosing Command 31 clears Middle Radio, and the other way round. |
| Tap again to clear | Tapping an item that is already selected deselects it, and the matching readout above disappears. |
| Selected items are outlined | The selected row in each list is shown with a border. |
| Selections are saved immediately | Your location, tone, and message are stored the moment you tap them, and restored the next time you open the Audio Hub — even after closing the app. |
| Tone and message are independent | You can have a tone selected, a message selected, both, or neither. |
Selecting an item in a list highlights it; tapping the same item again clears the selection. Your chosen location, tone, and message are saved and restored the next time you open the Audio Hub.
Getting Here
- Open an incident and open its Command View.
- In the command tools menu, tap Audio Hub.
- The Audio Hub panel opens, with your previous selections already restored.
Connecting and Listening
- Tap a location under Local Locations or Remote Locations. The Location readout above updates to show your choice.
- Tap Connect. The button reads CONNECTED once the session is open.
- Tap Receive to listen. The button turns orange while receive mode is on.
- Tap Receive again to stop listening.

Pick the location first, then connect — the Connect, Receive, and Transmit buttons all act on the location you have selected. Switching location while connected means disconnecting and reconnecting on the new one.
Transmitting and Sending Tones or Messages
- (Optional) Tap a Tone or a Message to load it for sending.
- Tap Transmit to go live. The button turns red while transmit mode is on.
- Speak, or tap Send to play the selected tone or message.
- Tap Transmit again to stop.

| Indicator | Meaning |
|---|---|
| Connect reads CONNECT | No session open. |
| Connect reads CONNECTED | The session is open on the selected location. |
| Receive is orange | You are listening to the location. |
| Transmit is red | You are live on the location. Anything picked up by the microphone goes out. |
| Both buttons plain | Neither receive nor transmit is on. |
Transmit stays on until you turn it off. Unlike the press-and-hold microphone on the Communications Tab, this is a toggle. While the button is red you are live — tap it again when you have finished speaking.
Receiving and transmitting use your device's microphone and speaker. Make sure the app has microphone permission and that your output volume is set appropriately before going live.
Loading and Empty States
| State | What you see |
|---|---|
| No tones configured | The Tones list is empty. Nothing is broken — your agency has not set any up. Ask an administrator to add them. |
| No messages configured | The Messages list is empty, for the same reason. |
| Nothing selected yet | The Location, Tone, and Message readouts above the controls are hidden until you pick something. |
| First time opening | The location, tone, and message lists show with nothing selected. Your choices are remembered from then on. |
| Reopening after use | Your previous location, tone, and message are already selected and shown in the readouts. |
How This Connects
Audio Hub is the command-post audio panel. It sits alongside the incident's own radio channels rather than replacing them.
- Where the lists come from. The three local positions and four command channels are fixed. Tones and pre-recorded messages come from your agency's Audio Hub configuration, stored on the device — so the lists appear even on a weak connection.
- Where your selections live. Your location, tone, and message choices are saved on your device, not on the incident. They follow you between incidents and survive closing the app. They are not shared with anyone else.
- How it relates to the incident radio. The Communications Tab works the incident's channel cards, with press-and-hold push-to-talk, per-channel volume, member lists, and recordings. Audio Hub works the radio positions and command channels with toggled receive and transmit. Both use the same microphone and speaker, so only one should be transmitting at a time — turn Transmit off here before pressing the microphone on a channel card.
- Where to reach it. Audio Hub is one of the tools on the Incident Side Menu, opening as a panel over the command board without disturbing your place on it.
- Offline. The panel opens and the lists still show, because they are held on the device. Connecting, receiving, transmitting, and sending all need a working connection and will not work.
- On reconnect. Your selections are still there, but the session is not. Tap Connect again, then turn Receive or Transmit back on.
Troubleshooting
| If this happens | What to do |
|---|---|
| The Tones or Messages list is empty | Your agency has not configured any. Ask an administrator to add them. |
| Connect does nothing | Select a location first — the controls act on the selected location. Then check your connection. |
| You cannot hear anything after connecting | Turn Receive on (it should be orange), then check your device volume and which output you are listening on. |
| Nobody can hear you | Check that Transmit is red. If it is, the app may not have microphone permission — allow microphone access in your device settings. |
| You are transmitting without meaning to | Transmit is a toggle, not press-and-hold. Tap it again to turn it off — it should no longer be red. |
| You selected a remote location and your local one cleared | That is expected. Only one location can be selected at a time. |
| The panel opens with a location already chosen | Your last selection is restored automatically. Tap it again to clear it. |
| Audio from a radio channel and from Audio Hub are fighting | Turn one off. Both use the same speaker and microphone. |
| The session drops when you close the panel | Reopen it and tap Connect again. |
| Send does nothing | Select a tone or a message first, and make sure you are connected. |
