These functions uses the GraphIsRenderable typeclass to assert that an audio graph is renderable by the web audio engine. This means, amongst other things, that it has a unique output device (ie speaker), that it does not have any dangling units not connected to a loudspeaker, etc.

Loops audio.

In WAGS, a "loop" is a universe whose changeBit increments by 1. That means that the structure of the graph is similar (no units added, none taken away) while some or none of its internal content (ie frequencies, gains, etc) has changed. This is accomplished using the change family of functions in WAGS.Change.

piece :: Scene (SceneI Unit Unit) FFIAudio (Effect Unit) Frame0
piece =
  WAGS.do
    start -- initial frame
    { time } <- env
    create (scene time) $> Right unit
    @> loop -- we loop by changing the scene based on `time` in the `env`
        ( const
            $ WAGS.do
                { time } <- env
                ivoid $ change (scene time)
        )
