Frequency Generator

 

 

  • Click play and drag the slider to alter the frequency
  • Sound is generated with a sine wave
  • Live spectrum display

Back in the early 80’s when I was a young teen, my dad bought me my first computer. It was a Commodore 64 sporting a [then] impressive 64K of memory ( compared to 16 million K in a 16GB computer today ). When you powered it on, you saw a command-line / Basic language interpreter. As a result, the first thing I learned was how to program in Basic. And the first program I wrote was generating sound frequencies, like say… 230hz.

For years I was dissapointed that ActionScript never had this ability, until Adobe finally released it in Flash Player 10. Generating raw frequencies is nothing exciting unless you want to annoy someone or their dog, but it’s the building block to something more exciting – synthesizers, drum machines, sequencers, and electronic music. I’ll post some links later of some developers who have taken this to a whole new level.

Portfolio Application

 

 
I was looking for a way to display CS4, CS5, Flex 3, and Flex 4 content all in one contiguous Flash experience. Turns out Flex 4 (FlashBuilder) was the best choice! It has proven very stable compared to CS5 as a swf in swf container environment, and does not seem to have any issues with Flash components. Whenever I had free time, I added more items to the portfolio or more features to the portfolio application.

Perhaps the biggest piece of programming in my online portfolio is the portfolio application itself. It’s not described anywhere in the portfolio, so I’m doing it here.

Here’s a list of features it has:

  • Database Driven: All portfolio items are assembled in a mysql database with info such as title, description, swf path, etc. From the database, you can choose items in the sliding “accordion” component, or the 3D image wheel – both on the left side.
  • Data Services: Data is fetched using Flash Remoting, I wrote the PHP services that feed my ActionScript structured, binary compressed data
  • Integrated WordPress Blog: Portfolio Items described in the blog are linked to the items in the portfolio, and the blog entries can be read while in the site. Click the “W” icons to see.
  • XML Menu system: I can easily add links and items that trigger AS3 functionality. Also, items can be launched in a JavaScript LightBox just by populating the xml
  • Windowing system: Allows you to view multiple items at once and move them around
  • Layout Control: Sizes to any ( decent ) resolution and automatically adjusts the layout to compensate, even when you resize the browser during viewing
  • 3D Item Selector: A custom PaperVision 3D component I built to select items. Selected items have a yellow 3D polygon above them, and highlighted items use a glow effect.
  • Deep Linking: Using Asual SWFaddress, you can link directly to individual portfolio items such as the Slideshow example: https://arnoldbiffna.s3.amazonaws.com/asd001/index.html#/id43
  • Shadowbox: Some portfolio items launch in a JavaScript box overlay. This allows it to launch html content in a separate window without “leaving” the site
  • Full Screen Mode: Click the “Max” button in the top right corner
  • Cascading Windows & Close All functionality: in the Appearance menu
  • Code Generated Wallpaper: in the Appearance menu. Uses a radial gradient

The structure of the portfolio could be reused to develop a large application where interactive modules are loaded and unloaded as needed. Floating windows and dialog boxes, along with the menu system are all elements of this. The code is an MVC ( Model View Controller ) structure that I find easy to update and build on.

The portfolio was rendered dynamically from the database, following a path of mysql -> PHP -> AMFPHP -> Flex.

MP3 Player

 

  • Stereo output level display
  • Spectrum Display
  • Volume Control
  • Balance Control
  • Stop, Play, Pause, Previous & Next Track
  • Loop feature
  • Time / position display
  • Flash Remoting based playlist, autogenerated

This version was an extension to the original version I made, adding the spectrum display. To avoid copyright issues, I grabbed some royalty-free music clips off the web and put them in a folder. The PHP getDirectory call in PortfolioService grabs all the mp3s in a folder and returns info about them to generate the playlist and play the music. Launch Flash!see it
