Software Integration for Applications with Audio Stream

Developing software systems by integrating the existing applications becomes mature and practical. Our previous works have successfully achieved the goal of intercepting/redirecting the data in the form of files and characters by adopting the wrapper technique. However, there are a huge number of multimedia applications today. In order to glue the multimedia based software applications, we try to build a wrapper module that redirects the audio data as the proposed approach in this paper. A Linux driver example that uses the ALSA library and a speech control system by integrating Skype and SphinxIII is also given to demonstrate our approach.
