Hello,

I’m trying to stream local (yes on client pc) mp3 files using actionscript 3 and adobe air runtime.

Scenario:  
1: Create new sound object and load an mp3.  
2: connect to the stream server ( red5 or flash media server ) and create new stream.  
3: attach microphone to the stream ( used only when the client wants to say something ) (default muted ).  
4: broadcast the loaded sound just like NetStream.attachAudio(mic:Microphone) would.

Everything works just fine until i get to the 4th step (broadcast sound object) since neither as3 nor adobe air seem to have this feature implemented.

I’ve tried using the NetStream.attachAudio(soundObject) that results in a conversion error stating that it cannot convert sound object to microphone object.

Maby extending the NetStream class to support attaching sound objects would be the answer here but since it`s actual sourcecode is closed this does not seem dooable.  
Or maby a sound object to microphone object converter ?

The application will run only as a desktop application using the AIR 1.0 runtime ( win / osx ) so cpu consumption related to browser usage is irrelevant.

## Yes i know Flash Media Server can do this with server stored mp3 / flv files… my app must be able to broadcast local files.

I cannot force my users to have 2 soundcards in their pc`s just to use this application

- 1st for the actual microphone
- and 2nd ( jack from sndcard 1 sound output -\> to snd card 2 microphone input jack ).

## maby an emulated sound output -\> microphone driver exists?

Any thoughts / ideas on the issue are grately apriciated.  
Thank you for your time,  
Micky.
