All of the major goals we set for the program were achieved before midterm with small exceptions. That means that audiodevinfo,audioplayer and audiorecorder (supposedly) work as they are described in MATLAB documentation here. There are some small exceptions. Notable properties that depend on the timer class don't work. These are used to issue command during recording and playback periodically. There still does not seem to be a clear agreement on what to do after the midterm, however there are several good possibilities.
