PicoTalk aims to be a simple and privacy oriented solution for group-calls. PicoTalk relies on a central server that is used for signalling and also routing and mixing of the audio signals. The goal is to provide true end-to-end encrypted group-calls such that the server does not have to be trusted. This is work-in-progress tough.
More on the protocol can be found here.
An example with a web user interface can be found here:
PicoTalk Python is the main implementation of picoTalk. This includes a server and client program written in Python.
PicoTalk Web is an alternative implementation of the client which can be run from a browser.
Install on Debian
Install the executables:
git clone [this repo] cd [this repo] cd picotalk-python python3 setup.py develop --user
Python installs the executable scripts by default into
$HOME/.local/bin. This folder must be in the
PATH environment variable. If it is not in the
PATH variable yet it can be added by appending the following line to
sudo apt install python3-pyaudio python3-numpy python3-scipy python3-aiohttp python3-nacl
For the server only the following is necessary
sudo apt install python3-numpy python3-nacl
uvloop for higher performance:
sudo apt install python3-uvloop
Run the client
picotalk-client -s my.server.com -r mySecretRoom
Run the server
picotalk-server # Use --uvloop to use uvloop.
The web client can be run by opening
picotalk-web/static/index.html in a browser or, alternatively,
In contrast to other browser based voice call solutions this does not use WebRTC but simply WebSockets.
