Flash version 10 has significant feature about audio, SampleDataEvent. Until this version, there was no way to generate a sound wave easily. Some people have tried to do that by rather magical way of how to make actionscript 3 play generated pcm wave data in Flash 9, however, now we have a straightforward API from Flash 10. I think this is a great improvement for hobby programmers who are interested in computer generated music. While it's shame from some perspective. Just this API finally brings us a point where old BASIC and PLAY statement could do a quarter centry ago!
You would find a lot of examples about SampleDataEvent, but some of those are wrong or uncompleted, since I think this API have been changed so often in beta version. And I wrote my version of simplest example for exercise.
There are a couple of tricks you might trap.- If you get an error message: "Flex error: type was not found or was not a compile-time constant: SampleDataEvent", you have to specify the Flash version to 10.0.0. Set -target-player option or Flex builder's Project's Properties - ActionScript Compiler - HTML Wrapper
- Some documentation might use Event.SAMPLE_DATA, but this is not true.
