Architecture

Representation for Melody Generate Resources

This app will help to capture the media elements, such as images, emojies, or humming audios, represented as MediaElement objects. Each specific media element such emojies have a subclass of MediaElement, such as EmojiElement. The following member variables should be emphasized:

• token: the emotional label of the corresponding media element, say, valence and arousal variable. However, in this version, this variable stands for the URL of the saved audio of this element, since currently we only concern the music generation for one single media element.
• identifier: identifies the media element.

Each subclass is in charge of managing the raw media file of them, such as the humming audio URL for HummingElement.

Media Token Generation

Once decided the media elements, TokenGenerator is in charge of generating token for them. In this version, TokenGenerator ask the backend for the corresponding audio, save it, then assign token with the URL of the audio.

Melody Generation

The melody of several elements is synthesised and used to generate melodies, the corresponding class is MelodyGenerator. However, in this version, there is no practical use of this class: it directly returns the token of the first MediaElement.

MelodyPresentation

By reading an array of MediaElements and the URL of the melody audio generated, MelodyPresentationView will play the video and audio for the generation. Subclass MelodyPresentationView for different visualization.

To Do List

• Parallel fetch token variable MediaElement when tapping addButton in MindViewController
• Permanent data storage structure
• Documentation
• MVC design
• Asking for authorization before utilizing resources, such as network and photo album.
