J'utilise Mumble (client de bureau) + Murmur (comme serveur LAN) + Plumble (client Android / iOS). Il en résulte la latence la plus faible que j'ai jamais atteinte (sonne presque comme un bouclage normal, théoriquement 7 ms de retard WiFi + 2x 10 ms de codec = 27 ms).
Fragments de README (rev 8c827fe)
Installez Mumble (client de bureau) + Murmur (serveur) + Plumble (client Android / iOS). Réglez les 3 programmes pour utiliser la meilleure qualité et une latence minimale. Configurez le client mobile pour toujours diffuser.
Pour installer Mumble + Murmur sur Ubuntu, vous pouvez utiliser:
sudo apt install mumble mumble-server
sudo systemctl stop mumble-server.service
sudo systemctl disable mumble-server.service
Copiez mic_over_mumblen'importe où - il utilisera ~/.mic_over_Mumblecomme répertoire de configuration.
Courez mic_over_mumble. Il démarrera le serveur sur LAN, puis démarrera Mumble (si un pseudo vous est demandé, entrez autre chose que SuperUser). Connectez ensuite votre appareil mobile au serveur LAN manuellement. Veuillez noter que l'application mobile Mumble a quelques problèmes .
Ensuite, configurez vos programmes pour utiliser "Monitor_of_Mumble" ou "VirtualMic" comme périphérique d'entrée (ils sont liés). Par exemple dans OBS:
Copie du mic_over_mumblescript (rev 8c827fe)

set -euo pipefail
# PAID = PulseAudio ID
# ID = PID / process ID

Please first load ALSA snd-aloop., donc je devais le faire:sudo modprobe snd-alooppuis j'ai dû exécuter le enmicclient-ubuntu-x86tant que root (en utilisantsudo). Et puis ça a marché, ouais.
