Mumble

Mumble is an app created for the noise dashboard project described in this medium article.

The setup is basically this:

• Raspberry PI 3 with the Respeaker board provides microphone
• Odas, in particular, odaslive runs on the PI and does great things such as detecting sources and potential energy levels (1)
• Odaslive sends its data in JSON to the TCP server that mumble provides (2)
• Clients willing to receive JSON data connect to mumble via websockets (3)
• Mumble echoes the JSON data to the clients
• Win & profit :)

Prerequisites

• Raspberry PI
  • respeaker software
  • odaslive
  • pm2 startup (systemctl enable pm2-pi)

Running the odaslive binary

Pm2 takes care of this, check ecosystem.config.js and update the app configuration if necessary:

 {
      name: 'odaslive',
      // you may want to adjust the path to your odas installation
      script: '~/odas/bin/odaslive -c ~/odas/config/odaslive/respeaker_4_mic_array.cfg',
      args: '',
      instances: 1,
      autorestart: true,
      watch: true,
      max_memory_restart: '512M',
    }

Deployment

The current ecosystem.config.js deploys this repo via SSH to a host named noise-pi. Feel free to update the configuration locally as necessary.

To deploy, run pm2 deploy production update
