WebPage that I research uses JS for doing some stuff. In the JS source code of the webpage I found this
i.audioUnmaskSource(e.src)
When I am trying to call this function from the console in Chrome it says
VM1452:1 Uncaught ReferenceError: i is not defined
at <anonymous>:1:1
Also Scope in developer tools says that i is an Object and is inside the Closure.
How can I access this function from Console in Chrome?
Scope of devtools
Here is the part of code that is called. It is a function audioUnamskSource as you can see: 
function r(e) {
    if (!a() && ~e.indexOf("audio_api_unavailable")) {
        var t = e.split("?extra=")[1].split("#")
          , n = "" === t[1] ? "" : o(t[1]);
        if (t = o(t[0]),
        "string" != typeof n || !t)
            return e;
        n = n ? n.split(String.fromCharCode(9)) : [];
        for (var r, s, l = n.length; l--; ) {
            if (s = n[l].split(String.fromCharCode(11)),
            r = s.splice(0, 1, t)[0],
            !i[r])
                return e;
            t = i[r].apply(null, s)
        }
        if (t && "http" === t.substr(0, 4))
            return t
    }
    return e
}
