Audio Capture from apps to microphone

A web browser plug in to capture audio from speaker output, and re-send that into the microphone stream. A standalone application has been coded that is capable of doing this as a proof of concept; what is now needed is new code base for a web browser plug-in that does not require a difficult installation, such as an ActiveX control, or Java. An example use is that a person selects audio files to play out the speaker, perhaps with a web browser. The web page will play with a standard audio plug in, such as Quicktime in Firefox, or Windows media player5, or with technology embedded in an <AUDIO> element that plays the audio out the speaker. Another window is open in the browser. The plug in will capture the audio stream, and insert the data stream back into the microphone stream. Thus a person can 'play sounds' into any other application in any other window. For example, an unmodified sound recorder open on the desktop would 'hea' an audio stream coming in the microphone, a voice app would think it 'heard' music playing or a person speaking, etc., but the audio is actually coming from any other app. ## Deliverables Our goal for this plug in is to replace an existing, standalone Win32 executable that captures speaker output and redirects it to the microphone. That application is not available any more. The preferred replacement would run entirely in the browser window. The minimum browser support is IE-only because this is likely to require ActiveX. If it is possible in any other plug-in technology that is not IE specific, or Windows specific, preference would be given to that proposal. The playback stream will always be coming from a web page that is open in a window. That web page runs JQuery AJAX that will repeatedly fetch playable sound in MP3 format (wav is possible but not preferred) asynchronously. The desired action is to stream this audio from this one 'web stream' into the PC's 'microphone stream' so that any other application 'hears' it. This may be accomplished in any way possible, such as mixing with the multimedia controls, direct injection into the windows messaging system, or any other method. There is no requirement that the plug in be able to 'hear' any other audio stream, such as what Soundleech accomplishes.
