Component 3B: Information Processes (Multimedia Complete)

posted Jul 14, 2009, 2:13 AM by Unknown user   [ updated Jul 14, 2009, 2:35 AM by Eddie Woo ]

Outline

A number of final additions and tweaks were performed. Most importantly, narration of the pages with text which can be turned on and off with the buttons described earlier. This was collected using the microphone built into the laptop which I use along with the sound recorder which is an accessory that comes with Windows. Secondly, I have included a short "welcome"on the first introduction page.
 
Tomorrow I shall begin uploading to the intranet and I will need to notify Joey so that she can do the critque and I'll have a post to notify Mr Woo where it is.
 

 
 
A record of the 7 information processes should be maintained as the multimedia system is developed, including relevant discussion of issues related to software/hardware constraints and design decisions (e.g. organising data: compression levels applied to images, audio and video data).
 
 
 
Collecting
  • Using the microphone built into the laptop to record my voice.
Organising
  • Sound Recorder saves my voice is .wma (Windows Media Audio file) which was converted to .mp3 so that it could be imported into Flash.
Anaylsing
  • None.
Processing
  • Flash file was constantly edited.
Storing and Retrieving
  • Saving the audio file with Sound Recorder then saving it again after conversion.
Transmitting and Receiving
  •  Downloading a .wma to .mp3 converter.
Displaying
  • Sound, video and the Flash document were displayed via speakers and the monitor,
 

Software/Hardware Constraints

I didn't actually have a .mp3 converter so I searched for freeware that was simple. In the end I chose the one called "Jodix Free WMA to MP3 Converter". Since I o nly had .wma files to convert and I never actually need .mp3 converters for anything else, I used this.
 
After importing the file into Flash, the audio became a bit "cloudy". The .mp3 and .wav file sounded fine but once displayed via Flash, it sounded a bit worse. I don't think this haas happened to any previous files but I think it might be that the microphone in the laptop doesn't collect the voice as loudly as the school's MP3 player. I have a extremely bad quality MP3 player with built-in mic which I could use as an alternative but it's, as I mentioned, extremely bad quality with a lot of background noise and such. I might just edit the files and make the volume a bit louder, because they do sound clearer that way.

Design Decisions

Nothing major, unless changing the colour of the on/off sound button to white for the narration counts. I placed them in the top right corner so that they are out of the way but can still be seen.
