Hi Team,
I am trying to add support for Audio in IE as a Flashback. I am getting
data as a Arraybuffer (6048 ) from the audio stream.
I have written below action script which is as follows:-
> package
> {
> import flash.display.*;
> import flash.events.*;
> import flash.external.*;
> import flash.media.*;
> public class guacamole extends Sprite
> {
> public var sound:Sound = null;
> public var buffer:Array;
> public function guacamole()
> {
> this.buffer = [];
> super();
> ExternalInterface.addCallback("write", this.write);
> }
> public function write(param1:String) : void
> {
> if(!this.sound)
> {
> this.sound = new Sound();
> this.sound.addEventListener(SampleDataEvent.SAMPLE_DATA,
> this.soundGenerator);
> this.sound.play();
> }
> this.buffer = this.buffer.concat(param1.split(" "));
> }
> public function soundGenerator(param1:SampleDataEvent) : void
> {
> var _loc_1:int = 0;
> var _loc_2:Function = param1.data.writeFloat;
> if(this.buffer.length < 4096)
> {
> _loc_1 = 0;
> while(_loc_1 < 4096)
> {
> _loc_2(0.00);
> _loc_1++;
> }
> return;
> }
> var _loc_3:Number = Math.min(this.buffer.length, 16384);
> _loc_1 = 0;
> while(_loc_1 < _loc_3)
> {
> _loc_2(this.buffer[_loc_1]);
> _loc_1++;
> }
> this.buffer = this.buffer.slice(_loc_3, this.buffer.length);
> }
> }
> }
Now I need to convert the stream of ArrayBuffer into a string of Integer
samples or Floating samples.
I need help to do that as I tried a lot but it's not working.
Please help me out to resolve the above issue or guide me to convert the
Raw PCM 16 bit Audio data to Floating samples between -1 to 1 .
Thanks and Regards,
