== Overview ==

Audio content connects an audio resource to a frame

 * Audio content is a content of a frame representing audio.
 * Audio resources are resources for audio.
 * Audio resources have the same information as any other resources plus specific information about the audio they are representing.
 * Audio content is responsible for returning the visual representation of the audio
 * There should be drag and drop support, so audio can be dropped onto a frame and  a audio content is created automatically from them.   Audio are scaled if they are bigger than the frame they are dropped onto.
 * There should be support for creating  a frame with audio content by choosing an audio file.
 * Audio resources should support clipping (in point, out point), rate and volume

== Task requirements ==

 * Define basic audio content.
 * Define basic audio resource.
 * Define how content work with frames to find a renderer (is this a scene?)

== Task result ==
The result of this task should be source code.

== Implementation idea ==
 * Create class !IAudioContent which is concrete implementation of org.sophie2.base.model.book.!FrameContent for audio.
 * !AudioContent should override mainResource() and return Prop<!AudioResource>.
 * Create class !AudioResource which is concrete implementation of org.sophie2.base.model.book.resource.!BookResource for audio resources.
 * !AudioResource should have methods:
  * inPoint
  * outPoint
  * startPoint (0)
  * endPoint (same as duration)
  * rate
  * volume
  * duration

 * Audio
  * Audio can be played without a frame presence (some script)
  * Audio can be represented by an image
  * Audio can have a controller
  * Determine if any of this should be part of the content, or kept elsewhere, ie does the content have any say in how the resource is represented on screen?
  * If yes, maybe contents should have extension points that keep the list of renderers for this content (and similar for audio and video, ie any content)

== How to demo ==
 * Create a frame with audio resource.
 * Check if the resource is set correctly and check if the information about the resource is correct.
 * Try changing the resource and check again the same things.
