Summary of Activities:

The subsequent summary is an analysis of the data storage sub patch that will be utilized to store and recall playlists within the soundscape generating environment.

Playlist Data Storage Sub Patch Summary

As shown in the picture above, the sub patch consists of three inlets, two outlets, and two main sections devoted to the storage and recall of data.

Inlet One:  receives information pertaining the index of the file and it’s placement within the playlist

Inlet Two:  collects file path data and location of the audio file on the hard disk

Inlet Three:  receives four different messages

• Write:  brings up a dialog box and saves playlist to a drive
  
• Read:  brings up dialog box and loads playlist information into the coll object
  
• Load:  send data from current playlist within the coll object to the outlets
  
• Clear:  clears data within the coll object
  

1. Outlet One: outputs index number information
   
2. Outlet Two:  outputs file path information
   

Storage Section

Consists of the coll and router object that is used in order to store and recall data to a text file.  The router object then directs the integer (in the this case, our index number) to the appropriate outlet.

Recall Section

Comprises of a metro object, counter, and router object.  The metro object sends bang messages (limited by the length of the playlist within the coll object) to the counter.  Once the counter receives a bang it will increase the outputted number by an increment of one, which then recalls file path and index information contained with the coll object.

Notes:

Tomorrow will consist of final preparations for the engineering phase on Monday, which will be primarily focused up finishing the modeling of the main environment’s modules and interface.
