createObjectURL() 관련 질문입니다.

// __.mr_src는 별도 지정

// audio/ogg

var ajax = new XMLHttpRequest();

ajax.responseType = 'blob';

ajax.open('GET',__.mr_src);

ajax.onreadystatechange = function () {

    if(ajax.readyState == XMLHttpRequest.DONE){

        console.log(ajax.response);

        func(URL.createObjectURL(ajax.reponse));

    }

}

ajax.send();

Uncaught TypeError: Failed to execute 'createObjectURL' on 'URL': Overload resolution failed.
