cahcing flash recorded audio in a bytearray on client

Question

Hello all,

I am building a small flash application to record audio from the client's computer. I wish to be able to use the microphone, store the recorded information in a byte array and then send it onwards. I saw the following piece of code that works fine with the camera:

        var _loc_1:BitmapData;
        var _loc_2:ByteArray;
        _loc_1 = new BitmapData(video.width, video.height, false, 13421772);
        _loc_1.draw(video, new Matrix());

        _loc_2 = PNGEncoder.encode(_loc_1);
        return Base64.encodeByteArray(_loc_2);

In order for this to work with audio I need classes like BitmapData and PNGEncoder that will work with audio and not just images \ video. Do you know of any such classes? Is it even possible?

Answer 1

I'm afraid that's not possible by using flash alone. You will have to stream the input to a server which then sends the data back. Here's two very short threads discussing it:

Also, about your code-example, I just want to say that unless you know what you're doing and need to store the data as a string, there's no need of encoding it with Base64, it'll waste both cpu-recourses and space.

Answer 2

i am searching for the same type of project. ie. capture audio from microphone from client computer and send to server side application. i have to use integrated flex+java application with eclipse IDE, and BlazeDS.

i am wondering is that only the way to upload media content to server side by Flash Media Server or RED 5 ???

it is not possible by other means -- byteArray method??
