A client for the Mumble voice chat system. Host or connect to one of the many community run public servers (see https://www.mumble.info). Mumla is an updated and maintained version (a fork) of the app Plumble.

Some of the features:

Certificate generation, import and export
Browse public servers
Voice activated transmission (the default), or different Push-to-talk buttons
Bluetooth headset support
Self-registration on server
Access tokens
Opus, CELT, and Speex codec support
Automatic reconnection
Tor support through the Orbot app
Text-to-speech for messages (turned on by default)
Light and dark theme

Voice activated transmission currently works best when using a headset. Echo cancellation and noise reduction needs work.
Tweaking the Detection threshold in the settings helps.

Mumla is copylefted libre software. Find out more at: https://mumla-app.gitlab.io/
