I am mind boggled at working out how to create a custom seekbar for an audio player using the tag and simple Javascript.

Current Code:

    First of all, don't use the progress element, it's a shitty element (for now) and styling it is a huge pain in... well it's boring (look at a little project I made, look at it (and it's juste webkit/moz)).

    Anyway, you should read the doc on MDN, it's very easy and with a lot of examples. What you are looking for is the currentTime attribute, here a little snippet :

    var audio = document.querySelector('#player')
    audio.currentTime = 60 // will go to the 60th second
    

    So what you need is to use the cross-multiplication (div is the element you use as a progress bar) : Where I clicked on div | THE TIME I WANT TO KNOW
    ————————————————————————————————————————
    Total length of div | The total time of my video/audio (audio.seekable.end())

    If you want smooth progress bar,try somethink like that

    HTML:

    <div class="hp_slide">
         <div class="hp_range"></div>
    </div>
    

    CSS:

    .hp_slide{
        width:100%;
        background:white;
        height:25px;
    }
    .hp_range{
        width:0;
        background:black;
        height:25px;
    }
    

    JS:

    var player = document.getElementById('player');    
    player.addEventListener("timeupdate", function() {
        var currentTime = player.currentTime;
        var duration = player.duration;
        $('.hp_range').stop(true,true).animate({'width':(currentTime +.25)/duration*100+'%'},250,'linear');
    });
    

    Pretty rough,but works

    Yes, it is possible using the timeupdate event of the audio tag. You receive this event every time the position of the playback is updated. Then, you can update your progress bar using the currentTime and duration properties of the audio element.

    You can see a working example in this fiddle
