audio

I would like to write a "daemon" application that will add a special audio filter (e.g. audio enhancement) to AudioRecord. The result should be as follows: Whenever any VoIP application (e.g. Skype,...) will create an AudioRecord, the captured audio will be first filtered using my daemon application before it reaches Skype. Is this doable ? For example can I use an AudioSessionID=0 to attach my filter to all the input channels ?
