How to change the Adobe Flash Player version in Adobe Flash CS3 - actionscript-3

Question

I want to create a flash application that records audio through the user's microphone and then make an upload to the server, in order to do that I've found this code:
import flash.media.Microphone;
import flash.events;
const DELAY_LENGTH:int = 4000;
var mic:Microphone = Microphone.getMicrophone();
mic.setSilenceLevel(0, DELAY_LENGTH);
mic.addEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
function micSampleDataHandler(event:SampleDataEvent):void {
while(event.data.bytesAvailable) {
var sample:Number = event.data.readFloat();
soundBytes.writeFloat(sample);
}
}
I couldn't test it yet, since it throws me this compiling error:
"1046:Couldn't find type or is not a constant during compiling time: SampleDataEvent"
After a research I've found that I have to update the Flash player version to compile to 10.0.0 in order to make it work, but I don't know how to do that. My IDE is the Adobe Flash CS3 Portable and most of the examples are for other IDEs like Flex, how can I do that?

Answer 1

You are not importing flash.events.SampleDataEvent and soundBytes is not defined in the micSampleDataHandler handler.
import flash.media.Microphone;
import flash.events.SampleDataEvent;
import flash.utils.ByteArray;
const DELAY_LENGTH:int = 4000;
var mic:Microphone = Microphone.getMicrophone();
mic.setSilenceLevel(0, DELAY_LENGTH);
mic.addEventListener(SampleDataEvent.SAMPLE_DATA, micSampleDataHandler);
function micSampleDataHandler(event:SampleDataEvent):void {
var soundBytes:ByteArray = new ByteArray();
while(event.data.bytesAvailable) {
var sample:Number = event.data.readFloat();
soundBytes.writeFloat(sample);
}
}
