Dear tom-s,

I tried copying you "full example" into a .js file i called test-clap.js and tried running it but get the following error message. I also changed the first line from "import ClapDetector from 'clap-detector'" to "const ClapDetector = require('clap-detector')". I am new to node and hope this is a beginner mistake.

~/watson/test-clap $ sudo node test-clap.js
/home/watson/watson/test-clap/test-clap.js:4
const clap = new ClapDetector()
^

TypeError: ClapDetector is not a constructor

the node_modules folder is in the same directory as ~/watson
I am running node version v9.11.2
strangely, it works when running your demo program as follows:
sudo node node_modules/clap-detector/lib/demo.js
