Class CMatchableSound

java.lang.Object
  projectpossibility.CMatchableSound

public class CMatchableSound
extends java.lang.Object

A previously recorded sound which can match itself against the incoming audio stream and generate an alert to the user. This initial implementation uses a simple matching scheme and can only handle constant frequency sounds. Later revisions will probably include more sophisticated functionality.
