Show Audio of Server Side Sound Card

Good Day,

I have a USB Audio device connected to my web server (RPi) running linux, apache2 and php.

I would like to display the sound level from the mic connected to the server via a webpage. I came across this html5 example which uses the:

navigator.getUserMedia

However this is for a microphone on the client side. Can someone advise how I could achieve a similar page that instead displays the level of the server side audio.

Thanks,
