Settings

Open Settings with the gear at the top right of the main screen. The sign-in screen has the same gear, so you can choose your audio devices before you sign in.

On a phone, tap a page to open it. On a wide screen, the pages are listed on the left and the open page is on the right. Each line in the list shows the current value, for example the microphone you use.

Settings are kept on each device. Your key levels and priorities are not settings. They follow you to every device. See Keys.

Disconnect at the bottom of the list signs you out and goes back to the sign-in screen.

Devices

This page chooses the microphone and the headphones or speaker livematrix uses. Every change applies at once, even during a call.

• Input Device (Microphone): the microphone. System Default follows your system’s choice. The Mic Level meter below it moves as you speak. In the apps it shows only while you are connected.
• Output Device (Speaker): the headphones or speaker. System Default follows your system’s choice.
• Play Test Tone plays a short tone so you can check you hear livematrix. In the browser and on phones it plays on the device you chose; on a computer it plays on the system’s default output. On an iPhone or iPad it plays only while you are connected.
• On an iPhone or iPad, one list, Audio Device (Microphone and Speaker), chooses both, because iOS always switches them together. It follows headsets as you connect them.
• Refresh Devices reads the list of devices again, for example after you connected a headset.
• Disconnect Audio stops audio on this device and keeps you signed in. Your keys still work, as with Control only (no audio). It shows only while you are connected with audio.

On Android, a Bluetooth headsets card appears if livematrix may not use Bluetooth headsets. Tap Allow, or Open Settings and turn on “Nearby devices”.

If a device you chose stops working, for example because a Bluetooth headset disconnected, a warning under the list says so and livematrix uses the system default until the device is back.

Audio

This page processes your voice on this device before livematrix sends it.

• Custom Mic Gain makes your microphone louder or quieter, up to about +6 dB. Default 0 dB. All the way down mutes it: nothing is sent, and Mic Level shows your microphone without the gain, greyed, so you can still test it.
• Mic Level shows how loud your microphone is, after the gain. It turns green above the gate. In the app it shows while you are connected.
• Custom Mic Gate silences your microphone while you are quieter than the threshold, so the room does not come through between sentences. Off by default. Drag the red marker on Mic Level, or tap where you want it, until the level stays left of it while you are silent. The left end turns the gate off. With a keyboard, the arrow keys move it by 1 dB.
• The reset button next to Custom Mic Gain sets it back to 0 dB, and the one next to Custom Mic Gate turns the gate off.
• Auto Gate turns on your device’s noise suppression. On by default.
• Mic Auto Gain lets your device even out your voice level. On by default.
• Echo Cancellation removes what your microphone picks up from your speaker. On by default. Leave it on unless you use a headset and your voice sounds cut off.
• Show audio level meters on home page shows a Mic and an Audio level meter above your keys. It is off by default.

Buttons

This page sets up Bluetooth push-to-talk buttons and keyboard keys on this device, and chooses what each one does. The browser version doesn’t have it. See Buttons.

Apple Watch

This page is only on an iPhone. It shows whether your watch and the livematrix watch app are connected, and sets up the watch’s Quick access buttons.

The front page of livematrix on your watch has four buttons. Hold one to talk. Tap an empty button here to choose a key for it; only keys that can talk are offered. Tap a button with a key to change or remove it. Choosing a key that is already on another button swaps the two. The fourth button always answers whoever last talked to you.

If the watch app is missing, install it from the Watch app on your iPhone.

Control API

This page is only on Windows, macOS and Linux. It lets Bitfocus Companion, and other control panels on the same computer, control livematrix through the app. See Stream Deck, X-keys and Companion.

• Enable local control API: on by default. Only programs on this computer can connect.
• Local API port: 9100 by default.
• Save Control API applies both. Nothing changes until you press it.

When the last control panel disconnects, every key it held is released.

Updates

This page is only on Windows, macOS and Linux. Phones update through their app store, and the browser version updates with your server.

• This copy shows the version and when it was built.
• Channel: Stable follows releases. Nightly is the latest development build, once a night. Off never checks.
• Status says whether an update is available. livematrix checks a minute after it starts, then every six hours. Check now checks right away.
• Install and restart appears when an update is downloaded. livematrix restarts to install it, which ends your session for a moment. Windows and Linux ask for an administrator’s password.
• Release notes opens what changed.

A copy you unpacked from a .zip or .tar.gz cannot replace itself. It offers Download instead. Unpack the new version in place of the old one.

Help

How keys work opens the three pages that explain a key again, with the practice key. See Learn how a key works.

Diagnostics

Export connection log saves a log of what happened with the connection and when, and opens your system’s share menu so you can send it to your administrator. In the browser it copies the log instead; paste it into an email.

The bottom of the page shows your livematrix version.
