Chad von Nau 518477f5f0 make sourceNode configurable (live mode) 
- Chrome has no way to destroy MediaElementSourceNodes, and only allows one per audio element
  - so if we want to to re-use an audio element, we must also pass a MediaElementSource node
  - get from ctx.sourceNode
  - use config.sourceNode to set
- also disconnect analyser/scriptProcessor nodes on destroy()
- also refactor gainWorkaround so gainNode goes after input node instead of before, easier to use

Chad von Nau 7463c1927a Safari createMediaElementSource volume workaround 2017-01-30 16:15:52 -08:00
Chad von Nau 3bdb8534ac make live mode compatible with Safari
