You need to convert the "audio_services" string into a JSON Object — Paolo Mossini, Dec 16 '19 at 13:55

You can use the JSON.parse function to change your JSON string into an object.
You can then access the property of this object using the . accessor, or the bracket ([ ]) accessor.

let audioObject = "{\"node-input-audio_services1\":\"network addresses\",\"audio_ip_1\":\"ports\",\"audio_port_1\":\"media clock rate\"}";

let object = JSON.parse(audioObject);
console.log(object['node-input-audio_services1'], ',', object['audio_ip_1'], ',', object['audio_port_1']);
