    var audio = new AudioC();
    audio.loadBlob(blob); // return Promise
    audio.loadUrl(url); // return Promise
    
    var totalTime = audio.getTotalTime();
    var currentTime = audio.getCurrentTime();
    
    audio.setGainValue(value); // 0 ~ 1.5
    audio.setPlaybackRate(pr); // 0.5 1 1.5 2
    
    audio.isPaused();
    
    audio.play();
    audio.pause();
    
    audio.skip(offset);
