CacoPhonic Choir voice engine

This is the part of CacoPhonic choir responsible for generating sound.

Install stuff:

Running on Raspberry PI

Install dependencies:

$ sudo apt-get install jackd1
$ sudo apt-get install supercollider

Add this line to /etc/security/limits.conf:

@audio          -       rtprio          99

Not sure if something needs to be done to reload limits.conf; rebooting after making this change might be a good idea.

$ DISPLAY=:0.0 sclang ccc_soundplayer.sc

Supercollider starts JACK (though we might want to have jack started by root as a service so it can run at a higher priority).

There is a mock word server written in node.js; it lives in the node-mock-ai folder. See the readme there for more details.

Quickstart:

$ cd node-mock-ai
$ npm install
$ CCC_SOUND_DIR=/path/to/sounds node server.js

Start JACK:

$ sudo jackd -dalsa -dhw:0

Start the sclang repl headless:

$ DISPLAY=:0.0 sclang
