How to seek with AudioContext

Question

I would like to create buttons that will play next/prev song on click, but they should seek the music on long press.

I did manage to change songs, but I couldn't find the seek methods. Also how to make it play from beginning?

And is there a way to determine how much have passed since the beginning of the song? I found that buffer have duration, but no sing of actual play time.

At init:

context = new (window.AudioContext || window.webkitAudioContext)()

To play song:

var buffer = song.buffer
var source = context.createBufferSource()
source.buffer = song.buffer
source.connect(analysers.main)
source.start(0, offset || 0)

Guess, you should use AudioBufferNode (it has ability to do seek) - https://developer.mozilla.org/en-US/docs/Web/API/AudioBufferSourceNode/start
